Cerebellum I

Question 1

The cerebellum and the basal ganglia act as

Answer 1

Feed-back system on the motor cortex that ultimately refine the motor output from the cortex

Question 2

Cerebellum assist the cortex in

Answer 2

Unconscious preparation, coordination of rhythmic patterns, and correct outcome and adaptation of actions

Question 3

It’s separated from the occipital lobe by

Answer 3

Tentorium

Question 4

Superiorly, we clearly distinguish an

Answer 4

Ant and post lobe

Question 5

Ant and post lobe are separated by

Answer 5

Horizontal sulcus or fissure

Question 6

On the inferior surface, we see mostly the

Answer 6

Post lobe, containing the Tonsils

Question 7

Ventrally on this inferior surface, the

Answer 7

Flocculonodular lobe

Question 8

Each lobe can be divided into

Answer 8

Lobules

Question 9

Inside the cerebellum:

Answer 9

Cortex
Subcortical white matter
Deep cerebellar nuclei (projecting outside cerebellum)

Question 10

Cerebellar outputs will exit via one of the three

Answer 10

Cerebellar peduncles

Question 11

Cerebellar nuclei

Answer 11

Fastigial nuclei = most medial
Interposed nuclei = in the middle
Dentate nucleus = largest, most lateral

Question 12

Vermis

Answer 12

Cord that courses from ant to post and divides the hemispheres

Question 13

Area bilateral to vermis, which receives different projections than those of vermis and hemispheres

Answer 13

Paravermis or paravermal cortices

Question 14

The cerebellar cortex is divided into 3 regions

Answer 14

Vermis→ related to Fastigial nuclei
Paravermal regions→ related to Interposed nuclei,
Lat hemispheres, largest areas→ related to Dentate nuclei

Question 15

Cerebellum receives info
