Q

What lobe of the cerebellum is involved with balance and eye movement

A

the flocculonodular lobe

17
Q

What does the lateral cerebellar hemisphere function to control

A

smooth, flowing movement

18
Q

The cerebellum in general functions to

A

coordinate control of voluntary movements, maintain muscle tone, control skeletal muscles and balance, control posture, locomotion, and fine motor coordination

19
Q

What is the name of the stalk that connects the hypothalamus to the pituitary gland

A

the infundibulum

20
Q

What does the epithalimus contain

A

the habenular nuclei and pineal body

21
Q

Why is the thalamus like a sensory filter

Whats the major control center for the autonomic nervous system and endocrine system

A

the hypothalamus

24

A

midbrain
pons
medulla
spinal cord

25
Q

Which body is involved with the onset of puberty

A

the pineal body

26
Q

What increases the surface area of the cerebrum

A

cerebral gyri

27
Q

The central sulculus seperates what

A

the frontal and parietal lobes

28
Q

What type of matter is the cortex of the cerebrum

A

gray matter

29
Q

What are the tracts of white matter that connect the left and right cerebral hemisphere

A

commissural fibers

30
Q

What the large C-shaped mass that connects 2 hemispheres

A

corpus callosum

31
Q

The cerebral medulla consists of what

A

many nerve tracts of white matter beneath the cerberal cortex

32
Q

The corpus striatum is composed of

A

the lentiform and caudate nuclei

33
Q

The limbic system is associated with what

A

basic survival instincts of nutrition, memory, and reproduction

34
Q

The limbic system contains what

A

cingulate gyrus of the of the cerebral cortex
denate gyrus of the hippocampus
olfactory cortex

35
Q

The cerebral aquaduct connects what

A

the 3rd and 4th ventricles

36
Q

the 3rd centricle is between what

A

2halves of the thymus

37
Q

What is required to move water soluble molecules across the blood brain barrier

A

mediated transport

38
Q

What 2 arteries supply the brain

A

carotid and vertebral

39
