type of descending pathway which stimulates and inhibits same lower motor neurons as corticospinal

A

medial pathway

32
Q

types of descending medial pathways

A

vestibulospinal, tectospinal, reticulospinal tracts

33
Q

descending medial pathway that deals with position and movement of the head

A

vestibulospinal tract

34
Q

descending medial pathway that deals with reflexive head movements

A

tectospinal tract

35
Q

descending medial pathway that deals with gross movements and muscle tone of trunks and proximal limb

A

reticulospinal tract

36
Q

descending pathways that deal with muscle tome and precise movements of distal upper limb. stimulate and inhibit same lower motor neurons as corticospinal

A

lateral pathway

37
Q

descending lateral pathway that starts in the red nucleus and crosses over. extends to cervical region of spinal cord. skeletal muscle of distal upper limb

A

rubrospinal tracts

38
Q

system that functions continuously and independently. no conscious effort needed and controls visceral activities– HR BP breathing

A

autonomic nervous system

39
Q

difference between autonomic and somatic

A

autonomic - two motor neurons (more synapse and ganglion) and somatic- one peripheral motor neuron( no peripheral synapse or ganglion)

40
Q

autonomic nerve fibers (2)

A

post ganglion neuron and pre ganglion neuron

41
Q

autonomic nerve fiber– soma in the CNS, axon leaves CNS and forms synapse in autonomic ganglia

A

pre ganglion neuron

42
Q

autonomic nerve fiber– soma is autonomic ganglion and axon goes to visceral effector

A

post ganglion neuron

43
Q

2 divisions of the autonomic nervous system

A

sympathetic and parasympathetic

44
Q

division of the autonomic nervous system that deals with stressful situations

A

sympathetic nervous system

45
Q

division of the autonomic nervous system that deals with restoring body to restful state

A

parasympathetic nervous system

46
Q

where does the preganglionic fibers originate in sympathetic nervous system. where is soma?

A

thoracic and lumbar region (T1- L1). soma is in CNS

47
Q

sympathetic ganglia =

A

chain ganglia and collateral ganglia

48
Q

part of sympathetic ganglia– a sequence of ganglia running parallel to spinal column on either side

A

chain of ganglia

49
Q

part of sympathetic ganglia– found in other parts of body. area for synapsing

A

collateral ganglia

50
Q

sympathetic chain ganglia in the body

A 
3 cervical
12 thoracic
2-5 lumbar
4-5 sacral
1 coccygeal
51
Q

what is the chain of ganglia innervated by

A

presynaptic fibers from nerves T1- L1

52
Q

preganglionic fibers leave _____ and enter chain via the ________

A

leave spinal nerve and enter white ramus

53
Q

3 possible paths of preganglionic fibers leaving

A
  1. synapse with ganglia with the point where they enter
  2. travel through chain to synapse with another ganglia
  3. pass through and go directly to collaterals ganglia or adrenal gland
54
Q

post ganglia exit via _____ to spinal nerve then to the _______ OR via ____ to ______

A

grey ramus; effector

sympathetic nerve; effector

55
Q

process of collateral ganglia

A

presynaptic fibers go straight through chain ganglia without synapsing

  1. synapse with post ganglionic fiber in collateral ganglia
  2. post synaptic fibers usually go to abdominal viscera
56
Q

major collateral ganglia

A

celiac
super mesenteric
inferior mesenteric

57
Q

modified collateral ganglia. preganglionic fibers go straight through the chain and collaterals to get to it. enter straight into the medulla of the adrenal gland

A

adrenal medullae

58
Q

modified post synaptic fibers into glandualr cells

A

chromaffin cells

59
Q

adrenal medullae allows for the stimulation of hormones _____ and _____

A

norepinephrine and epinephrine

60
Q

sympathetic activation involve what NT– first one, second one

A

ACh and norepinephrine

61
Q

what receptor picks up ACh in sympatetic activation. function?

A

nicotinic receptors. stimulate post ganglionic neuron or adrenal medullae

62
Q

what receptor picks up norepinepherine in sympathetic activation. function ?

A

adrenergenic receptor. stimulate target tissues

63
Q

effects of sympathetic nervous system

A

inc alterness, energy euphoria, excite cardiovascular and resp centers, inc muscle tone, mobilization energy

64
Q

parasympathetic system

A

originates from neurons in midbrain, pons, medulla, and saccral region of spinal cord. exits CNS via cranial nerve 3, 7, 9, 10 and saccral 2-4

65
Q

preganglionic fibers of parasympathetic do

A

cranial nerves 3, 7, 9 go to ganglia near target organs. cranial berve 10 and saccral converge to plexuses, exit plexus and to target organ

66
Q

post ganglionic fibers of parasympathetic do

A

close to within target organs. effects of system more direct and localized

67
Q

NT released during parasympathetic activation

A

ACh

68
Q

receptor used to pick up ACh

A

nicotinic and muscarinic receptors. nico used to stim post ganglionic neurons and musc used to stimulate target tissues

69
Q

used to clean up ACh

A

acetocholinesterase
