Pancreas
________: regulates the level of sugar in the blood.
PET
________ scan: a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task.
Reticular formation
________: a nerve network that travels through the brainstem and thalamus and plays an important role in controlling arousal.
Cerebellum
________: coordinates our voluntary movements, processes sensory input, balance, nonverbal learning, and memory, and is located at the back of the brain.
Amygdala
________: two lima bean sized neural clusters in the limbic system; linked to emotion.
Pons
________: help to coordinate movements, located just above the medulla in the brainstem.
MRI
________: a technique that uses magnetic fields and radio waves to produce computer- generated images of soft tissue.
Electroencephalogram
________: an amplified recording of the waves of electrical activity sweeping across the brains surface.
Interneurons
________: neurons in the brain and spinal cord that process information, and intervene between the sensory inputs and motor outputs.
Ovary
________: secretes female sex hormones.
Thalamus
________: the brains sensory control center, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.
Hypothalamus
________: the region of your brain that controls the pituitary gland, a neural structure located below the thalamus; it directs several matinence activities such as eating, drinking, and body temp. is linked with emotion and reward.
Parathyroids
________: help regulate the level of calcium in the blood.
Cerebral hemispheres
________ ': two halves of the brain.
Medulla
________: the base of the brainstem, controls heartbeat and breathing.
Hippocampus
________: processes conscious memories.
FMRI
________: a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans.
CT scan
________: a series of x- ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brains structure.
Limbic system
________: neural system located below the cerebral hemispheres; associated with emotions and drives (including the hippocampus, amygdala, and hypothalamus)
reflex
a simple automatic response to sensory stimulus, (such as a knee- jerk response)
Hormones
________: chemical messengers, that are manufactured by the endocrine glands travel through the bloodstream and affect other tissue.
Endocrine system
________: the bodys "slow "chemical communication system; a set of glands that secrete hormones into the bloodstream.
FMRI scans
________ show brain function as well as brain structure.
Brainstem
________: the oldest part and the central core of the brain, beginning where the spinal cord swells as it enters the skull; the brainstem is responsible for the automatic survival functions.
MRI
________ scans show brain anatomy.
nervous system
the bodys speedy, electrochemical communication network, it consists of all nerve cells from the peripheral and central nervous systems
central nervous system
the brain and spinal cord (the bodys decision maker)
peripheral nervous system
the sensory and motor neurons that connect the central nervous systems to the rest of the body(responsible for gathering information and transporting it to different parts of the body)
nerves
bundles of axons that form neural "cables" connecting the central nervous system with muscles, glands, and sense organs
sensory neurons
neurons that carry incoming information from the sensory receptors to the brain and spinal cord for processing
motor neurons
neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
interneurons
neurons in the brain and spinal cord that process information, and intervene between the sensory inputs and motor outputs
somatic nervous system
one part of the peripheral nervous system, that controls the bodys skeletal muscles
autonomic nervous system
one part of the peripheral nervous system, controls the glands and the muscles of the internal organs and has two divisions
sympathetic nervous system
division of the autonomic nervous system that arouses and expends energy, specifically in stressful situations
parasympathetic nervous system
division of the autonomic nervous system that calms the body, conserves energy
examples of the sympathetic nervous system
pupils dilate, heartbeat accelerates, it inhibits digestion, stimulates glucose release by the liver, stimulates the secretion of epinephrine and norepinephrine, and stimulates ejaculation in males
examples of the parasympathetic nervous system
contracts pupils, slow heartbeat, stimulates digestion, stimulates gall bladder, contracts bladder, allows blood flow to sex organs
reflex
a simple automatic response to sensory stimulus, (such as a knee-jerk response)
endocrine system
the bodys "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
hormones
chemical messengers, that are manufactured by the endocrine glands travel through the bloodstream and affect other tissue
adrenal glands
a pair of endocrine glands located just above the kidney and secrete hormones that help arouse the body in times of stress
pituitary gland
endocrines systems most influential gland, under the influence of the hypothalamus the pituitary gland regulates growth and controls other endocrine glands
Hypothalamus
the region of your brain that controls the pituitary gland, a neural structure located below the thalamus; it directs several matinence activities such as eating, drinking, and body temp. is linked with emotion and reward
Thyroid gland
affects metabolism
Adrenal glands
the inner part of this gland helps to trigger the "fight or flight" response
testis
secretes male sex hormones
ovary
secretes female sex hormones
pancreas
regulates the level of sugar in the blood
parathyroids
help regulate the level of calcium in the blood
parts of the endocrine system
hypothalamus, thyroid gland, adrenal glands, testis, ovary, pancreas, parathyroid, and pituitary gland
lesion
tissue destruction used by scientists to experimentally deconstruct brain tissue to learn about different parts of the brain
electroencephalogram
an amplified recording of the waves of electrical activity sweeping across the brains surface
CT scan
a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brains structure
