24
Q

lumbure puncture

A
  • to extract spinal fluid

- between L3 and L4

25
Q

gray matter

A
  • in spinal butterfly structure
26
Q

- surround gray matter

27
Q

pia mater

A
  • inner membrane

- weaker

28
Q

dura mater

A
  • outer membrane

- stronger

29
Q

afferent

A
  • sensory

- to the brain

30
Q

efferent

A
  • motor

- to the body

31
Q

cerebellum and brain stem function

A
  • motor control
  • timing
  • balance
32
Q

thalamus

A
  • main relay center for senses
33
Q

hypothalamus

A
  • ANS control
  • four Fs
  • hormone secretion of pituitary
34
Q

basal ganglia

A
  • motor control
  • motor learning (w/ hippocampus)
  • three nuclei
35
Q

central sulcus

A
  • seperates frontal and parietal

- coronally

36
Q

Brodmann areas

A
  • 52

- based on morphology and density of cells

37
Q

primary cortices

A
  • motor, somatosenory, auditory, visual
38
Q

association cortices

A
  • motor somatosensory, auditory, visual
39
Q

ventricular system

A
  • CSF
  • shock absorption
  • weight reduction
40
Q

cerebral aqueduct

A
  • produces CSF

- damage leads to hydroencephalus

41
Q

CSF

A

= cerebrospinal fluid

42
Q

arachnoid granulations

A
  • in supereior saggital sinus

- remove CSF

43
Q

superior saggital sinus

A
  • location of arachnoid granulations

- removing CSF

44
Q

A
  • caudate nucleus
  • globus pallidus
  • putamen
