Unit 2

Question 1

Functions of the medulla

Answer 1

Has autonomic centers that regulate breathing, blood pressure; direct swallowing, coughing, vomiting reflexes

Question 2

Functions of the pons

Answer 2

Relays data from hemispheres to cerebellum

Works with medulla to maintain balance/posture, breathing

Question 3

Functions of midbrain

Answer 3

Participates in eye movement control

Has relay nuclei of auditory & visual systems

Question 4

Functions of cerebellum

Answer 4

Coordinates planning/execution of full body movement, balance/posture

Also coordinates head/eye movements

Integration of sensory/motor data

• sensory data about position from spinal cord
• sensory data about balance from vestibular organs
• motor data from cerebral cortex

Question 5

Functions of thalamus

Answer 5

Processes almost all sensory data sent to cerebral cortex

Process almost all motor data sent from cerebral cortex to brain and spinal cord

Question 6

Functions of hypothalamus

Answer 6

Has centers to regulate body temp, hunger, water balance

Endocrine gland, controls pituitary hormone secretion

Secretes releasing and release-inhibiting hormones into hypophysial portal blood to affect anterior pituitary

Has neuronal cell bodies of posterior pituitary which secrete ADH & oxytocin

Question 7

Functions of cerebral hemispheres

Answer 7

Perceptions

Higher motor functions

Cognition

Memory

Emotion

Question 8

Function of basal ganglia

Answer 8

Chooses which action to perform at the moment

Question 9

Functions of amygdala

Answer 9

Emotion

Question 10

Functions of hippocampus

Answer 10

Memory

Question 11

Functions of cerebrospinal fluid

Answer 11

Provides constant, controlled environment for brain cells

Protects brain from endogenous/exogenous toxins

Prevents local neurotransmitter escape to circulation

Allows lipid-soluble solutes to permeate

Inhibits passage of non-lipid-soluble solutes
