Cerebellum

Question 1

The __________ is a midline structure that separates the two hemispheres of the Cerebellum

Answer 1

Vermis

Question 2

What are the 3 lobes of the Cerebellum?

Answer 2

Anterior
Posterior (w/ tonsils)
Flocculonodular

Question 3

Inferior part of the Posterior Cerebellar lobe; can herniate in Chiari 1/2 malformation

Answer 3

Tonsils

Question 4

A Choroid Plexus is located in the 4th ventricle, directly abutting the…

Answer 4

Cerebellum

Question 5

Lobe of the Cerebellum; responsible for equilibrium and balance, and thus tied with the vestibular system; oldest part of the brain overall

Answer 5

Flocculonodular

Question 6

Which Lobe of the Cerebellum coordinates with the Vestibular system?

Answer 6

Flocculonodular (responsible for equilibrium and balance) (connection to inner ear??)

Question 7

Lobe of the Cerebellum; responsible for stereotyped movements such as walking; insult can result in ataxic gait

Answer 7

Anterior (and Vermis)

Question 8

Lobe of the Cerebellum; responsible for coordination and modulation of FINE limb movements; insults can result dysmetria, intention tremor and dysdiadocholinesis (can’t play Patty Cake)

Answer 8

Posterior

Question 9

According to Somatopy, the Vermis of the Cerebellum controls the (limbs/body) and the Hemispheres control the (limbs/body)

Answer 9

Vermis: trunk
Hemispheres: limbs

*similar to the Cerebrum

Question 10

Describe the Cerebellar Peduncles and their connections to the Brainstem (3 total)

Answer 10

Superior: to Midbrain
Middle: to Pons
Inferior: to Medulla

Question 11

Cerebellar Peduncle; has only OUTPUTS (to red nucleus and Thalamus); connects to Midbrain

Answer 11

Superior Peduncle

Question 12

Cerebellar Peduncle; has only INPUTS (from Cerebral Cortex); connects to Pons

Answer 12

Middle Peduncle

Question 13

Cerebellar Peduncle; has only INPUTS (from Brainstem and Spinal Cord); connects to Medulla

Answer 13

Inferior Peduncle

Question 14

ALL connection of the Cerebellum are responsible for controlling the (contra/ipsi)lateral part of the body

Answer 14

Ipsilateral

Question 15

STEP 1 ONLY: What are the 4 deep nuclei of the Cerebellum

Answer 15

Fastigial
Globose
Emboliform
Dentate

Question 16

STEP 1 ONLY: Climbing fibers from the inferior olive will communicate with what cell in the Cerebellum?

Answer 16

Purkinje cell (controls information to the cerebellar nuclei)
