32
Q

proprioceptors skin receptors

A

movement/body location (located in all of the body)

33
Q

local anesthetic blocks and doesn’t block what

blocks nociceptors but not ruffinis

34
Q

olfactory

A

smell

35
Q

gustatory

A

taste

36
Q

somatosensory

A

touch

37
Q

humunculus

A

“map of body” created by feel

38
Q

what “eats” up the left over or extra chemicals in the synapse?

A

the neurons specific enzyme (chemical name + “ase”)

39
Q

true or false: there is a threshold of the chemicals to transfer from an axon to dendrite (all or none rule)

A

true

40
Q

the positive charge is always wehr the ____ is going

A

sodium

41
Q

the negative charge is always where the ____ is going

A

potassium

42
Q

what triggers neurotransmitters to release

A

calcium

43
Q

the 8 words to remember synaptic physiology order

A

receives it, pumps it, depolarized it, move it down to the axon bulb and channel in some calcium, vesicles position, neurotransmitters released
in… the synapse, enzymes eat the extra in the gap, neuron is resting, sodium is exiting, potassium is entering, and now we’re back to polarized

44
Q

cells on the axon

A

schwann’s cells (they make the myelin)

45
Q

gaps between schwann cells

A

nodes is ranvier “signal boosters”

46
Q

insulating fatty layer that speeds transmission in the axon

A

myelin sheath

47
Q

Central nervous system uses what kind of cells

A

oligodendrites

48
Q

peripheral nervous system uses what kind of cells

A

schwann cells

49
Q

sympathetic nervous system responses

A

blood vessels narrow, increase in heart rate, pupil dilation, inhibits digestion system, lungs relax, contraction of arrector pili (hair stand up), decrease in salivation

50
Q

parasympathetic system responses

A

blood vessels dilate, decrease in heart rate, pupils close, secretion in digestion system, bronchi close, relaxation of arrector pili, increase in salivation

51
Q

matter layers top to bottom

A

dura, anarchiod, pía

52
Q

medulla oblongata is what to the corpus callosum
