Study These Flashcards
A

basal ganglion

25
- dorsal to pons and medulla - coordinates motor activity - carries instruction - maintains equilibrium - made of gray and white matter
cerebellum
26
in center and houses all cell bodies
gray matter
27
on outside and contains the tracts
white matter
28
- dura mater - arachnoid - pia mater
meninges
29
- provides maximum protection to brain - tough and fibrous; connective tissue - between skull and arachnoid
dura mater
30
- thin and nonvascular - space between it and pia mater - contains CSF
arachnoid
31
- totally lines brain and spinal cord inside and out | - very thing and has network of blood vessels
pia mater
32
- four holes that connect to the subarachnoid space | - circulate CSF
ventricles
33
- contains all ascending sensory tracts and descending motor tracts - contains cranial nerve nuclei
midbrain
34
- contains the 4th ventricle
pons
35
- vital body functions
medulla
36
- reflex control to the periphery - links brain to periphery - sensory info - motor from brain to visceral organs and skeletal muscle
spinal cord function
37
- beings as a continuation of the medulla - 1 cm diameter - housed in vertebrae - connects medulla at the level of foramen magnum
spinal cord anatomy
38
- striated tissue - sensory input from muscles, skin, joints - motor output to skeletal muscles, extra ocular muscles, tongue muscles
general somatic
39
- smooth or cardiac tissue - internal vital organs - sensory input from visceral organs - output to muscles of visceral organs
general visceral
40
- sensory input from vision, balance, inner ear | - olivocochlear bundle
special somatic
41
- sensory input from tongue and olfaction | - output to muscles of palate, face, mouth, pharynx, larynx
special visceral
