| a branch of psych concerned with the links between biology and behavior | ||
| a nerve cell; the basic building block of the nervous system | ||
| the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body | ||
| the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands | ||
| a layer of fatty tissue; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next | ||
| a neural impulse, generated by the movement of positively charged atoms in and out of channels in the axon's membrane | ||
| The junction between the axon tip of the sending neuron and the dendrite | ||
| Chemical messengers that traverse the synaptic gaps between neurons | ||
| a neurotransmitter that enables learning and memory and also triggers muscle contraction | ||
| natural, opiatelike neurotransmitters linked to pain control and to pleasure | ||
| neurotransmitter;influences movement, learning, attention, and emotion | ||
| affects mood, hunger, sleep arousal; neurotransmitter | ||
| helps control alertness and arousal; neurotransmitter(undersupply can depress mood) | ||
| major inhibitory neurotransmitter (undersupply linked to seizures, tremors, and insomnia. | ||
| a major excitatory neurotransmitter | ||
| can mimic effects of a neurotransmitter | ||
| the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems | ||
| The brain and spinal cord | ||
| hte sensory and motor neurons that connect central nervous system to the rest of the body | ||
| neural cables containing many axons. they connect the central nervous system with muscles, glands, and sense organs | ||
| neurons that carry incoming information from the sense receptors to the central nervous system | ||
| neurons that carry outgoing information from the central nervous sytem to the muscles and glands | ||
| central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs | ||
| the division of the peripheral nervous system that controls the body's skeletal muscles | ||
| the part of the peripheral nervous system that controls the glands and the muscles of the internal organs. Its sympathetic division arouses; its parasympathetic division calms | ||
| the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations | ||
| division of the auto. ner. system that calms the body, conserving its energy | ||
| a simple, automatic, inborn response to a sensory stimulus, such as the knee-jerk response | ||
| interconnected neural cells; | ||
| the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream | ||
| chemical messengers, mostly those manufactured by the endocrine glands that are produced in one tissue and affect another | ||
| a pair of endocrine glands just above the kidneys. the adrenals secrete the hormones epinephrine (adrenaline) and norepinphrine (noradrenaline) which help to arouse the body in times of stress | ||
| the endo. system's most influential gland. under the influence of the hypothalamus, it regulates growth and controls other endo. glands | ||
| tissue destruction | ||
| An amplified recording of the waves of electrical activity that sweep across the brain's surface | ||
| a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task | ||
| a tech. that uses magnetic fields and radio waves to produce comp. generated images that distinguish among diff. types of soft tissue | ||
| a tech. for revealing blood flow | ||
| the oldest part and central core of the brain, beginning where the spinal cord swells; the brainstem is resp. for automatic survival functions | ||
| the base of the brainstem; controls heartbeat and breathing | ||
| a nerve network in the brainstem that plays an imp. role in controlling arousal | ||
| the brain's sensory switchboard, directs msgs to the sensory receiving areas in the cortex | ||
| processes sensory input and coordinating movement output and balance | ||
| a doughnut-shaped system of neural structs; asso. with fear and aggression and drives such as those for food and sex | ||
| linked to emotion; part of the limbic system | ||
| directs several maintenance act. (eating, drinking, body temp.); helps govern the endo. system via the pituitary gland | ||
| intricate fabric of interconnected neural cells that covers the crebral hemispheres; the body's ultimate control and info processing center | ||
| cells that support, nourish, and protect neurons | ||
| the portion of the cerebral cortex; involved in pseaking and muscle movemnts and in making plans and judgments | ||
| recieves sensory input for touch and body position | ||
| includes the visual areas, located in the lack of the head | ||
| lies above the ears, receives auditory info | ||
| rear of the frontal lobes that controls voluntary movements | ||
| registers and processes body touch and movement sensations | ||
| areas of the cerebral cortex that are involved in higher mental functions such as learning, remembering, thinking, and speaking | ||
| impairment of language | ||
| controls language expression, directs muscle movements involved in speech | ||
| controls language recpetion; involved in language comprehension and expression | ||
| the brain's capacity for modification | ||
| the large band of neural fibers connecting the two brain hemispheres and carrying msgs between them | ||
| the two hemispheres of the brain are isolated by cutting the connecting fibers between them |
