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
