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
