1. 
Somatic Nervous System
 
controls the voluntary movement of skeletal muscles
 
2. 
Autonomic Nervous System
 
Control "smooth muscle" systems, such as digesting, arousal, and heart beat
 
3. 
Peripheral Nervous System
 
The network of Sensory and motor neurons that connect the Central Nervous System to the body. Includes ANS, and SNS
 
4. 
Central Nervous System
 
Brain and Spinal cord
 
5. 
Sympathetic Division----Autonamic System
 
Governs responses to stress under contitions of threat or emergency, when action must be quick and powerfully energized---arousing
 
6. 
Parasympathetic
 
Monitors the routine operation of the body's internal functions---calming
 
7. 
Frontal Lobe
 
Reasoning, planning, parts of speech, and problem solving (movement, exectutive controls)
 
8. 
Parietal Lobe
 
Perception of stimuli related to touch, pressure, temperature and pain (somatosensory)
 
9. 
Temporal Lobe
 
Perception and recognition of auditory stimuli(hearing and memory)
 
10. 
Occipital Lobe
 
visual information, color, movement, shape, shading, recognition of human faces, (vision)
 
11. 
When the brain is damaged, oh goodness!, what will you do???
 
The brain can change it's functions and shape
 
12. 
psychosocialdwarfism
 
condition when children don't grow from not feeling other's human touch.
 
13. 
Cerebrum
 
Largest part of brain responsible for sensing, thinking, learning, emotion, consciousness, and voluntary movement
 
14. 
Corpus callosum
 
The bridge of fibers in the middle of the brain that passes information between the two cerebral hemispheres
 
15. 
Thalamus
 
Part of brain that serves as the relay for cortex; handles incoming and outgoing signals---motor controls to muscles and glands
 
16. 
Hypothalamus
 
Part of brain responsible for regulating basic biological needs; hunger, thirst, temperature control
 
17. 
Pituitary Gland
 
"Master" gland that regulates other endocrine glands----secretes growth hormones
 
18. 
Hippocampus
 
Part of limbic system involved in learning and memory
 
19. 
Pons
 
Part of brain involved in sleep and arousal
 
20. 
Medulla
 
Part of brain responsible for regulating largely unconscious functions such as breathing and circulation---controls reflexes; vomiting, coughing, sneazing
 
21. 
Reticular Formation
 
Group of fibers that carry stimulation related to sleep and arousal through brainstem
 
22. 
Spinal Cord
 
Responsible for transmitting information between the brain and the rest of the body; handles simple reflexes as well
 
23. 
Cerebellum
 
Structure that coordinates fine muscle movement and balance.
 
24. 
Amygdala
 
Part of limbic system involved in emotion and aggression
 
25. 
Sensory Neuron
 
Recieve info. from sensory receptors
 
26. 
Interneuron
 
transfers and interprets impulses between neurons
 
27. 
Motor Neuron
 
sends impulses to muscles and glands
 
28. 
Dendrite
 
Part of neuron that recieves info.
 
29. 
Soma
 
Part of neuron that integrates info. from dendrites---decides wether or not to fire neural impulses
 
30. 
Axon
 
Transmits messages to terminal buttons
 
31. 
Terminal Buttons
 
end of Axon that secretes neurotransmitters in response to impulse.
 
32. 
Neurotransmitter
 
Chemical messenger that acts within the synapse
 
33. 
Synapse
 
point at which the neurons interconnect
 
34. 
Myelin sheath
 
Insulation----speeds up transmission in axon
 
35. 
Glial Cells
 
Produce myelin sheath, they also provide scaffolding for neurons. There are many more glial cells than neurons 10:1
 
36. 
Reuptake
 
process when neurotransmitters are pumped back into the transmitting neuron, otherwise they are broken up by enzymes
 
37. 
Glutamate
 
main excitatory neurotransmitter in the CNS
 
38. 
GABA
 
the most common inhibitory neurotransmitter. too much->unmotivated and sluggish; too little->anxiety and epilepsy
 
39. 
Acetylchlorine
 
neurotransmitter that facilitates some kinds of learning and memory. messenger for motorneurons too, controls muscle contraction. too much->tremors; too little->anxiety and epilepsy
 
40. 
Norepinephrine
 
neurotransmitter that coincides with heart rate, vigilance, stress, and mood. too much->jittery; too little->unmotivated and sluggish
 
41. 
Endorphines
 
neurotransmitter that creates pleasure, reduces pain, and influences emotion.too much->feel no pain
 
42. 
Dopamine
 
neurotransmitter that influences movement, learning, and attention. too much->schizophrenia; too little->parkinson's
 
43. 
Seratonin
 
neurotransmitters that regulate mood, hunger, sleep, and arousal. too much-> always sleepy; too little->OCD depression, anxiety
 
44. 
Agonist
 
Drug taht increases the synthesis or release of neurotransmitters; mimics neurontransmitters by fitting into receptors; inhibits reuptake; inhibits the enzymes that break them down.
 
45. 
Antagonist
 
Drug that interfers with the release of neurotransmitters;occupies and blocks receptors; inhibits the affects of agonist drugs
