Definitions: Brain Structures and Neurotransmitters
Acetylcholine: A neurotransmitter that plays a key role in muscle movement and is involved in the processes of learning, memory, and mood regulation.
Action Potential: A rapid change in the electrical potential across a cell membrane, which is essential for the transmission of nerve signals.
Adrenal Glands: Endocrine glands located above the kidneys that produce hormones such as adrenaline and cortisol, which are involved in the body's response to stress and other functions.
All-or-Nothing Principle: The principle that states that once a nerve impulse reaches a certain level of intensity, it will fire and travel the length of the neuron without losing any intensity.
Amygdala: A part of the brain involved in the processing of emotions, especially fear and pleasure responses.
Aphasia: A condition that impairs a person's ability to process language, often resulting from damage to the brain, typically in the left hemisphere.
Association Areas: Regions of the cerebral cortex that integrate sensory and motor information, and are involved in complex mental functions such as learning, memory, and thinking.
Auditory Cortex: The part of the temporal lobe that processes auditory information.
Axon: A long, slender projection of a nerve cell that conducts electrical impulses away from the neuron's cell body.
Brain Stem: The part of the brain that controls basic functions such as breathing, heart rate, and blood pressure.
Broca's Area: A region of the brain located in the frontal lobe, associated with the production of speech.
Cerebellum: A structure located at the back of the brain that is responsible for coordinating voluntary movements, posture, and balance.
Cerebral Hemispheres: The two halves of the cerebrum, which are responsible for higher cognitive functions.
Cerebrum: The largest part of the brain, responsible for higher brain functions such as thought and action.
Corpus Callosum: A thick band of nerve fibers that connects the two cerebral hemispheres and facilitates communication between them.
Dendrites: Branch-like extensions of a neuron that receive signals from other neurons.
Dopamine: A neurotransmitter involved in many functions, including mood, reward, and motor control.
Endorphins: Neurotransmitters that act as natural painkillers and are involved in feelings of pleasure and well-being.
Frontal Lobe: The part of the brain associated with reasoning, planning, problem-solving, and motor control.
Genotype: The genetic makeup of an individual organism.
Glutamate: The most abundant excitatory neurotransmitter in the central nervous system, involved in learning and memory.
Hippocampus: A region of the brain involved in the formation of long-term memories and spatial navigation.
Hormone: A chemical messenger produced by the endocrine glands that regulates various bodily functions.
Hypothalamus: A region of the brain that controls the autonomic nervous system and regulates various bodily functions, including body temperature, hunger, and thirst.
Interneuron: A neuron that transmits impulses between other neurons, especially as part of a reflex arc.
Limbic System: A set of brain structures, including the hippocampus and amygdala, involved in emotion, motivation, and memory.
Medulla: The base of the brainstem that controls vital autonomic functions such as breathing and heart rate.
Motor Cortex: The part of the cerebral cortex that is involved in the planning, control, and execution of voluntary movements.
Motor Neuron: A type of neuron that conveys nerve impulses from the central nervous system to muscle fibers or glands.
Myelin Sheath: A layer of fatty tissue that insulates the axons of neurons and enables faster transmission of nerve impulses.
Neuron: A specialized cell transmitting nerve impulses; a nerve cell.
Neurotransmitters: Chemical messengers that transmit signals across the synapses between neurons.
Norepinephrine: A neurotransmitter and hormone that plays a role in the body's response to stress.
Occipital Lobe: The lobe of the brain that processes visual information.
Parasympathetic: The division of the autonomic nervous system responsible for calming the body and conserving energy.
Parietal Lobe: The lobe of the brain involved in processing sensory information and spatial awareness.
Phenotype: The observable physical or biochemical characteristics of an organism, determined by both genetic and environmental factors.
Phenylketonuria: A genetic disorder that results in the inability to metabolize phenylalanine, leading to intellectual disabilities if untreated.
Pineal Gland: A small endocrine gland in the brain that produces melatonin, which regulates sleep-wake cycles.
Pituitary Gland: An endocrine gland that controls other endocrine glands and regulates various bodily functions.
Pons: Middle part of the brainstem that coordinates facial movement, balance and hearing.
Plasticity: The brain's ability to reorganize itself by forming new neural connections throughout life, especially in response to injury or disease.
Reflex: An involuntary and nearly instantaneous movement in response to a stimulus.
Reticular Formation: A network of neurons in the brainstem involved in controlling arousal and attention.
Sensory Neuron: A nerve cell that transmits sensory information from the sensory organs to the central nervous system.
Serotonin: A neurotransmitter that regulates mood, appetite, and sleep.
Somatosensory Cortex: The part of the brain that processes sensory information from the body, such as touch and temperature.
Spinal Cord: A long, thin, tubular bundle of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.
Sympathetic: The division of the autonomic nervous system responsible for the body's fight-or-flight response.
Temporal Lobe: The lobe of the brain involved in auditory processing and the formation of long-term memory.
Terminal Buttons: The small knobs at the end of axons that secrete neurotransmitters.
Thalamus: A structure in the brain that relays sensory and motor signals to the cerebral cortex.
Thyroid Gland: An endocrine gland in the neck that produces hormones regulating metabolism and growth.
Visual Cortex: The part of the cerebral cortex that processes visual information.
Wernicke's Area: A region of the brain associated with the comprehension of language and the production of meaningful speech.
