Question 10

Superior colliculi

Answer 10

Coordinate head and eye movement

Question 11

Inferior colliculi

Answer 11

Auditory relay from hearing receptors of the ear to the sensory cortex.
Reflex response to sound

Question 12

Cerebral peduncles

Answer 12

Vertical pillars that hold up the cerebrum

Question 13

Substantia nigra

Answer 13

Produces dopamine, causes parkinson’s, regulates movement

Question 14

Reticular formation

Answer 14

Extends through the medulla oblongata, pons and midbrain. Composed of loosely clustered neurons in white matter, integrates information from all regions of the CNS, and incorporates the mechanisms that regulate sleep and wakefulness

Question 15

Superior cerebellar peduncles

Answer 15

Connecting cerebellum to midbrain carry efferent info from cerebellum to the brain

Question 16

Answer 18

Pneumotaxic center)

Question 19

Pontine respiratory group (center) definition

Answer 19

Involved in inspiration and expiration

Question 20

Middle cerebellar peduncles

Answer 20

Carry one-way communications from the pons to the cerebellum, advising the cerebellum of voluntary motot activities

Question 21

Medulla Oblongata

Answer 21

Relay of impulses, reticular formation, pyramids, olives, cardiovascular center, respiratory center, inferior cerebellar peduncles, decussation of the pyramids

Question 22

Decussation of the pyramids

Answer 22

Crossover , each cerebral hemisphere chiefly controls the voluntary movements of muscles on the opposite side of the body

Anterior, posterior and flocculonodular lobes, arbor vitae, superior cerebellar peduncles, inferior cerebellar peduncles and middle cerebellar peduncles

Question 26

Arbor vitae

Answer 26

The tree-like white matter tracts that provide afferent and efferent sensory and motor information to and from the cerebellum

Question 27

Inferior cerebellar peduncles

Answer 27

Connect medulla and cerebellum, convey sensory info to the cerebellum from muscle receptors throughout the body
