the body's electrochemical communication circuitry, made up of billions of interconnected cellsN S
the brain's special capacity for modification and storageP
sensory nerves that transport information to the brainA N
motor nerves that carry the brain's outputE N
networks of nerve cells that integrate sensory input and motor outputN N
the brain and spinal cordC N S
the network of nerves that connects the brain and spinal cord to other parts of the body. It is divided into the somatic nervous system and the autonomic nervous systemP N S
the division of the PNS consisting of sensory nerves, whose function is to convey information to the CNS, and motor nerves, whose function is to transmit information to the musclesS N S
the division of the PNS that communicates with the body's internal organs and monitors processes such as breathing, heart rate, and digestion. It consists of the sympathetic and paA N S
the division of the autonomic nervous system that arouses the bodyS N S
the division of the autonomic nervous system that calms the bodyP N S
nerve cells that are specialized for processing informationN
cells that provide support and nutritional benefits in the nervous systemG C
the part of the neuron that contains the nucleus, which directs the manufacture of substances that the neuron needs for growth and maintenanceC B
branches of a neuron that receive and orient information toward the cell body; most neurons have numerous ______s.D
the part of the neuron that carries information away from the cell body to other cellsA
the layer of fat cells that encases and insulates most axons; speeds up the transmission of nerve impulsesM S
the stable, negative charge of an inactive neuronR P
the brief wave of postive electrical charge that sweeps down the axon during the transmission of a nerve impulseA P
the idea that once an electrical impulse reaches a certain level of intensity, it fires and moves all the way down the axon without losing any of its intensityA O N P
tiny junctions between two neurons, generally where the axon of one neuron meets the dendrites or cell body of another neuronS
chemical substances that carry information across the synaptic gap from one neuron to the nextN
a drug that mimics or increases a neurotransmitter's effectsA
a drug that blocks a neurotransmitter's effectsA
the lowest portion of the brain, consisting of the medulla, midbrain, and ponsH
located between the hindbrain and forebrain, a region in which many nerve-fiber systems ascend and descend to connect the higher and lower portions of the brainM
a midbrain system that consists of a diffuse collection of neurons involved in stereotypical behaviors, such as walking, sleeping, or turning to atend to a sudden noiseR F
the region of the brain that includes much of the hindbrain (excluding the cerebellum) and the midbrainB S
the highest level of the brain; key structures inclued limbic system, thalamus, basal ganglia, hypothalamus, and cerebral cortexF
loosely connected network of structures - including the amygdala and hippocampus - that play important roles in memory and emotionL S
forebrain structure that functions as a relay station to sort information and send it to appropriate areas in the forebrain for further integration and interpretationT
large clusters of neurons, located above the thalamus and under the cerebral cortex, that work with the cerebellum and the cerebral cortex to control and coordinate voluntary movemB G
small forebrain structure involved in regulating eating, drinking, and sex; directing the endrocrine system; and monitoring emotion, stress, and reward.H
highest level of the forebrain, where the highest mental functions, such as thinking and planning, take placeC C
the part of the cerebral cortex at the back of the head that is involved in visionO L
the portion of the cerebral cortex just above the ears that is involved in hearing, language processing, and memoryT L
the part of the cerebral cortex just behind the forehead that is involved in the control of voluntary muscles, intelligence, and personalityF L
area of the cerebral cortex at the top of the head that is involved in registering spatial location, attention, and motor controlP L
area of the cerebral cortex that processes information about body sensationsS C
area of the cerebral cortex that processes information about voluntary movementM C
region of the cerebral cortex in which the highest intellectual functions, including thinking and problem solving, occur; also called association areasA C
the large bundles of axons that connects the brain's two hemispheresC C
a set of glands that regulates the activities of certain organs by releasing their chemical products (hormones) into the bloodstreamE S
chemical messengers manufactured by the endocrine glandsH
an important endocrine gland at the base of the skull that controls growth and regulates other glandsP G
important endocrine glands that are instrumental in regulating moods, energy level, and the ability to cope with stressA G
threadlike structures that contain genes and DNA. Humans have 23 pairs in the nucleus of every cellC
a complex molecule that contains genetic information.....
the units of hereditary information - short segments of chromosomesG
the principle that, if one gene of a pair governing a certain characteristic is dominant and one is recessive, the dominant gene overrides the recessive gene. A recessive gene exerD R G P
an individual's genetic hereitage; his or her actual genetic materialG
the expression of an individual's genotype in observable, measurable characteristicsP
the response of individuals to changes in circumstances and events that threaten their coping abilitiesS
circumstances and events that threaten individuals and tax their coping abilitiesS
