Unit 1 and 2

6. the part of the neuron that contains the nucleus,the cells life-support center
10. basic building block of nervous system
11. a neural impulse; a brief electrical charge that travels down
12. an early school of thought promoted by Wundt, about structure of human mind
13. a fatty tissue layer segmentally encasing the axons of some neurons
15. the neuron extension that passes messages through its branches to other neurons or to muscles or glands
16. the view of psychology that psychology should be an objective science and studies behavior without reference to mental processes
19. the science of behavior and mental processes
20. "morphine within"
21. the idea that knowledge comes from experience
22. the junction between the axon tip of the sending neuron and the dendrite or cell
23. cells in the nervous system that support, nourish, and protect neurons; they also play a role in learning, thinking, and memory
24. a neurons often bushy, branching extensions that receive and integrate messages, conducting impulses toward cell body

1. thinking that does not blindly accept arguments and conclusions
2. chemical messengers that cross the synaptic gaps between neurons
3. explored how mental and behavioral processes function
4. a historically significant perspective that emphasized growth potential
5. study of mental processes, such as occur when we perceive learn,remember,think,communicate, and solve problems
7. a neurotransmitters re absorption
8. in neural processing, a brief resting pause hat occurs after a neuron has fired
9. a molecule that increases a neurotransmitter action
14. the process of looking inward, to observes one psychological processes
17. the level of stimulation required to trigger a neural impulse
18. a molecule that inhabits or blocks a neurotransmitter action
