AP Psychology Unit 2

3. linked to pain control and pleasure
5. a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next
6. neural "cables" containing many axons
7. muscle action, learning, associated with alzheimer
9. uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue
10. scan a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
13. the part of the peripheral nervous system that controls the glands and the muscles of the internal organs
17. calms the body, conserving its energy
20. the sensory and motor neurons that connect the central nervous system to the rest of the body
23. neurons that carry outgoing information from the central nervous system to the muscles and glands
24. an amplified recording of the waves of electrical activity that sweep across the brain&surface
25. a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body
26. the oldest part and central of the brain, beginning where the spinal cord swells as it enters the skull; responsible for automatic survival functions
28. a neural impulse; a breif electrical charge that travels down an axon

1. neurons that carry incoming information from the sense receptors to the central nervous system
2. a branch of psychology concerned with the links between biology and behavior
4. nervous system the division of the perihperal nervous system that controls the body's skeletal muscles
6. the body's speedy, electrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous systems
8. central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs
11. the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
12. interconnected neural cells - with experience, networks can learn
14. chemical messengers that traverse the synaptic gap between neurons
15. tissue destruction
16. the level of stimulation required to trigger a neural impulse
18. arouses& accelerate the body, mobilizing its energy in stressful situations
19. the base of the brainstem; controls heartbeat and breathing
21. a simple, automatic, inborn response to a sensory stimulus
22. a nerve cell; the basic building block of the nervous system
27. the brain and spinal cord
28. the extention of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands
