Infant Development (chapter 2) Alcohol Favorite toy as a transitional Baby’s wants and needs are the same thing Non-emotion induced tears- see two things water and salt. Emotion induced tears- water, salt,endorphins, and endoxified protiens. Toxins and endorphins reduce stress. Prolactin and oxytocin (frequency, duration, intensity) Egotistical response Bioevolutionary speaking crying is a survival instinct. Babies absorb about 10 times radiation than adults. Closer chromosomes with female chimp than a human male. culture dictates how much time we spend with our babies. Bowlby said that culture is so powerful that it can override instincts. Behaviorism theory can say that instinct do not exist in humans. About 77% of infants (12 m) 40 or more hours a week. About 8 of our babies are not raised with their parents. It matters how we raise our kids, because they will grow up and make choices for us. About 75%-80% of women said they were working for personal fulfillment. Women would rather be at work than be with their children at home. Snowball effect- To be able to read those cues, it takes times. so when you don’t spend time with them you wont pick up their cues. Quality time involves quantity. Having kid at work can also be counted as quality because they can still ask questions and make memories. It’s just about the amount of time you spend. They have the highest turnover rates than any other job Cultural feminist- belief that women are superior than men because they will never do things that women could. Feminism-men and women should be treated equally. Formula is digestible and allows you to sleep longer but when awake stomach hurts Ferberize a baby to make them sleep longer. Works for any age, put in crib, pat their back (3 time) and turn off lights and leave room Come back 20 minutes and pat back again and leave without turning light on. Next night 21, 22, 23, and increase each night. Can leave baby alone because they are starving and also since they don’t have a sense of time (they think you leave forever) We spoil babies (holding too much, pick up when crying) 1912 We spoil babies the exact why we spoil fruit, (leave them alone) Anecetipmen is also to ADHD, brain is not receiving signals Day 2 Relational play- understanding what goes with what. Stranger anxiety- you like people you don’t know at all (8-9 months) Categorical anxiety- they don’t like glasses etc. Visual cliff- she was born knowing not to go off cliff. Strange situation test- You can not measure attachment Other countries when given money for having a baby only have one baby. ( Sweden) Independence cannot be taught. Our need for sleep that drives what happens to our babies 80% world’s co-sleeping because everyone sleeps better. Moms slept with babies in the past. Needs have never changed for babies from very first baby to the ones present. According Erickson the first year is where we determine if the word is a safe place. Emotional needs for babies are as important as their physical needs. Letting a child cry it out is perceived as child abuse in other countries. You can be taken to jail and/or ticketed. (Other cultures) Formula feeding is super convenient 88% of white educated American pediatricians In American in curbs where SIDS occurred the most Royal rode to the unconscious - you will deal with the hard stuff when you are awake. Boy and girls develop differently All around the world, all babies start using words at 12 months If not start using words 12 months then might check hearing. Nouns are the first words Chomsky ( are speaking is innate) Talking to us or someone to talk for us The more you’re talked to the more you are verbal fluently The word no Bali is a country where babies that are perceived to be devine Refuse to babies on the ground up until the first 6 months 6 months ceremony 6 months can crawl, and sit up Breastfeeding, staying close proximity, co-sleeping Wearing your baby much more likely to read their cues Make them scared of the whole world Developmentally appropriate More child is held the happier they are, more nursed she will be happier (oxytocin, prolactin) We call this an ancient physiological interdependence. Advanced motor skill, more vertigo Baby is learning through the mothers experience Instinct Less crying ( more time together) Non-medicated births, baby-led breastfeeding, co-sleeping Colic can be withdrawal- formula fed - stomach issues - co-sleeping— miss mom Motor skills- body doing everything the mother is doing Lower vertigo, because you get a workout Separated from their mothers they cry Higher self esteem, they are more self -reliant- lower rates of anxiety and depression Strong sense of self Mesozoic era Two types of mammals -caching hide their young to protect them while they go look for food. Their babies can remain silent for long periods of time Their milk is very very high is protein very high is fat Caring mammals- their young are born helpless, they can’t regulate body temperature, they need constant contact with their mom for protection, their milk is low in fat and low in protein designed for continuous and on demand feeding Humans are caring mammals Monkeys, apes, Pigmies - long term breastfeeding 4-5 years Learn from experiences Babies worn long term !Kung- very very tall people They breastfeed 4-5 years Not having babies often Very sexual people Master gland- nursing often, gland stays silent Breastfeeding becomes spaced not they can have a child Not having periods Sleep 4-7 hours, period comes Baby nursing almost all the time It’s nutritional and its medicinal, and attachment formation More the baby suckle the more milk you make What kind of birth control pill- cannot breastfeed on birth control About 200 years ago the crib was introduced According to John bowlby separation form attachment figure can be physiological damaging Bowlbys primary attachment theory Tears and constant waiting for mom to return Very sad, no affect, low affect Deattachment- know she’s not going to come back Can be long term, Can impair child’s ability to form loving relationships Internal working model is our prototype for all later relationship Bowlby hypothesized in the 1940s that separation from mother can leave to chronic anxiety and depression It is impossible to measure neurotransmitters of a brain of a living human The number one cause of disability is depression Babies don’t have a concept to time Existential sense of self Dichotomy of the public and private sphere Is where you nurture and raise children Family was a man and a women and their children Three types of women Those that have to be mothers They love kids, they want take them back to their parents She doesn’t want kids, doesn’t like them Bought a house 10.5 years after they got married 600 and 25 ft 28 years old car Few months after marriage Car is no 20 years old It is not 600 and 25 ft If we breastfed for 12 months and you save 7,

Chapter 7:6 Study Guide NERVOUS SYSTEM P179-187 Nervous System-complex, highly organized system that coordinates all the activities of the body. *The basic structural unit of the nervous system is the neuron, or nerve cell. It consists of a cell body containing:  Nucleus  Nerve fibers called dendrites (carry impulses toward the cell body)  Single nerve fiber called axon (carry impulses away from the cell body) Many axons have a lipid covering called a myelin sheath, which increases the rate of impulse transmission and insulates and maintains the axon. The axon of one neuron lies close to the dendrites of many other neurons. The spaces between them are known as synapses. Special chemicals, called neurotransmitters, located at the end of each axon allow the nerve impulses to pass from one neuron to another. Nerves are a combination of many nerve fibers located outside the brain and spinal cord. Meninges are membranes or protective lining that covers the brain and spinal cord. Afferent, or sensory, nerves carry messages from all parts of the body to the brain and spinal cord. Efferent, or motor, nerves carry messages from the brain and spinal cord to the muscles and glands. Associative, or internuncial, nerves carry both sensory and motor messages. There are two main divisions to the nervous system: 1. 2. Central nervous system: consists of the brain and spinal cord Peripheral nervous system: consists of the nerves. A separate division of the peripheral nervous system is the autonomic nervous system. This system controls involuntary body functions. *Brain-mass of nerve tissue well protected by membranes and the cranium, or skull. The main sections include:  Cerebrum-the largest and highest section of the brain. Responsible for: reasoning, thought, memory, speech, sensation, sight, smell, hearing, and voluntary body movement.  Cerebellum-section below the back of the cerebrum. Responsible for: muscle coordination, balance and posture, muscle tone.  Diencephalon-section between the cerebrum and midbrain. o Thalamus-acts as a relay center and directs sensory impulses to the cerebrum. o Hypothalamus-regulates and controls the autonomic nervous system, temperature, appetite, water balance sleep and blood vessel constriction and dilation. Also involved in emotions such as anger, fear, pleasure, pain and affection.  Midbrain-the section located below the cerebrum at the top of the brain stem. Responsible for conducting impulses between brain parts and for certain eye and auditory reflexes.  Pons-located below the midbrain and in the brain stem. Responsible for conducting messages to other parts of the brain; for certain reflex actions including chewing, tasting, and saliva production; and for assisting with respiration.  Medulla oblongata-the lowest part of the brain stem. Connects with the spinal cord and is responsible for regulating heartbeat, respiration, swallowing, coughing, and blood pressure. The spinal cord continues down from the medulla oblongata and ends at the first or second lumbar vertebrae. *The meninges are three membranes that cover and protect the brain and spinal cord. 1. 2. 3. Dura mater-thick, tough, outer layer Arachnoid membrane-delicate and web like Pia mater-closely attached to the brain and spinal cord and contains blood vessels that nourish the nerve tissue. The brain has four ventricles, hollow spaces that connect with each other and with the space under the arachnoid membrane. The ventricles are filled with a fluid called cerebrospinal fluid. This fluid circulates continually between the ventricles and through the subarachnoid space. It serves as a shock absorber to protect the brain and spinal cord. It also carries nutrients to some parts of the brain and spinal cord and helps remove metabolic products and wastes. After circulating, it is absorbed into the blood vessels of the dura mater and returned to the bloodstream through special structures called the arachnoid villi. The peripheral nervous system consists of the somatic and autonomic nervous systems. The somatic nervous system consists of 12 pairs of cranial nerves and their branches and 31 pairs of spinal nerves and their branches. Some of the cranial nerves are responsible for special senses such as sight, hearing, taste, and smell. The Autonomic nervous system is an important part of the peripheral nervous system. It helps maintain a balance in the involuntary functions of the body and allows the body to react in times of emergency. *There are two divisions to the autonomic nervous system: Sympathetic nervous system: prepares the body in times of emergencies. Prepares the body to act by increasing heart rate, respiration, and blood pressure and slowing activity in the digestive tract. This is known as the fight or flight response. Parasympathetic nervous system: After the emergency, this slows down the heart rate, decreases respirations, lowers blood pressure and increases activity in the digestive tract. Cerebral Palsy is a disturbance in voluntary muscle action and is caused by brain damage. Lack of oxygen to the brain, birth injuries, prenatal rubella, and infections can all cause cerebral palsy. Cerebrovascular Accident or CVA (stroke) occurs when the blood flow to the brain is impaired, resulting in a lack of oxygen and a destruction of brain tissue. CVA includes loss of consciousness; weakness or 1. 2. paralysis on one side of the body (hemiplegia); dizziness; dysphagia (difficulty swallowing); visual disturbances; mental confusion; aphasia (speech and language impairment); and incontinence. When a CVA occurs, immediate care within the first three hours can help prevent brain damage. Treatment with thrombolytic or “clot-busting” drugs such as TPA (tissue plasminogen activator) can dissolve the blood clot and restore blood flow to the brain. Aphasia is a speech or language impairment. There are different types. ALS is amyotrophic lateral sclerosis. Also called Lou Gehrig’s disease. This is a chronic degenerative neuromuscular disease. The cause is unknown. Carpal tunnel syndrome is a progressive, painful condition of the wrist and hand. It occurs when the median nurse is pinched or compressed. Concussions are traumatic brain injuries, usually from a blow to the head by an accident, injury or fall. The brain slides back/forward and forcefully hits against the skull. Think of it like a bruise on the brain. Encephalitis is an inflammation of the brain and is caused by a virus, bacterium, or chemical agent. Epilepsy or seizure syndrome is a brain disorder associated with abnormal electrical impulses in the neurons of the brain. Hydrocephalus is an excessive accumulation of cerebrospinal fluid in the ventricles and, in some cases, the subarachnoid space of the brain. It is usually cause by a congenital (at birth) defect, infection, or tumor that obstructs the flow of cerebrospinal fluid out of the brain. The condition is treated by the surgical implantation of a shunt (tube) between the ventricles and the veins, heart, or abdominal peritoneal cavity to provide for drainage of the excess fluid. Meningitis is an inflammation of the meninges of the brain and/or spinal cord and is caused by a bacterium, virus, fungus, or toxins such as lead and arsenic. Multiple Sclerosis (MS) is a chronic, progressive, disabling condition resulting from a degeneration of the myelin sheath in the central nervous system. Neuralgia is nerve pain. Inflammation, pressure, toxins, and other disease cause it. Paralysis usually results from a brain or spinal cord injury that destroys neurons and results in a loss of function and sensation below the level of injury. Hemiplegia is paralysis on side of the body and is caused by a tumor, injury, or CVA. Paraplegia is paralysis in the lower extremities or lower part of the body and is caused by a spinal cord injury. Quadriplegia is paralysis of t harems, legs, and body below the spinal cord injury. Parkinson’s disease is a chronic, progressive condition involving degeneration of brain cells, usually in persons over 50 years of age
