18
Q

spinothalamic tracts function

A

convey pain and temp (lateral) and crude touch (anterior)

19
Q

spinocerebellar tracts function

A

convey proprioception information from muscle spindles, golgi tendon organs, and touch and pressure receptors

20
Q

spinoreticular tracts function

A

convey deep and chronic pain to reticular formation of brainstem

21
Q

corticospinal tract function

A

voluntary motor control

22
Q

vestibulospinal tract function

A

control of muscle tone, antigravity muscles, and postural reflexes

23
Q

rubrospinal tract function

A

assist in motor function/ coordination

24
Q

tectospinal tract function

A

assists in head-turning responses to visual stimuli

25
Q

sympathetic nervous system

A

fight or flight

26
Q

parasympathetic nervous system

A

rest and digest

27
Q

stretch/myotactic reflex

A

stimulated by muscle stretch; functions for maintenance of muscle tone, support agonist muscle contraction, and provide feedback about muscle length

28
Q

inverse stretch reflex

A

stimulated by muscle contraction; functions to provide agonist inhibition, diminution of force of agonist contraction, stretch-protection reflex

29
Q

gamma reflex loop

A

allows muscle tension to come under control of descending pathways

30
Q

flexor withdrawal reflex

A

stimulated by cutaneous sensory stimuli; functions as a protective withdrawal mechanism to remove a body part from a harmful stimuli

31
Q

crossed extension reflex

A

stimulated by noxious stimuli and reciprocal action of antagonists (flexors of one side are excited, so extensors of the same side inhibited and opposite occurs on contralateral side); functions to coordinate reciprocal limb activities such as gait

32
Q

CNI function

A

sense of smell

33
Q

CNII function

A

vision- color, clarity, peripheral vision, pupillary light reflex

34
Q

CNIII function (affected)

A

movement of eyeball (lateral strabismus)
opens eyelids (ptosis)
constricts pupil (dilation)

35
Q

CN IV function

A

look down and in (towards nose)

36
Q

CN VI function (affected)

A

look out/abduct eyes (medial strabismus)

37
Q

CN V function

A

sensation to face
afferent corneal reflex
sensation to anterior tongue
dampens sound

38
Q

CN VII function

A

movement of face
efferent corneal reflex
taste to anterior tongue
dampens sound

39
Q

CN VIII function

A

balance and hearing

40
Q

CN IX function

A

afferent gag reflex
posterior tongue sensation and taste

41
Q

CN X function (affected)

A

efferent gag reflex (uvula will deviate towards opposite side of lesion)
visceral

42
Q

CN XI function

A

shoulder elevation

43
Q

CN XII function (affected)

A

tongue protrusion (tongue will deviate towards side of lesion)
