Cerebellum

A nurse is caring for a patient who exhibits the following symptoms:

→ inability to maintain balance while walking

→ normal intelligence

→ can initiate voluntary movements although they are somewhat uncoordinated

→ decreased tone in the skeletal muscles.

The patient is probably suffering from a condition that affected the

• midbrain.

• brainstem.

• cerebellum.

• basal ganglia.

Select all that apply. What are the three major regions of the cerebellum?

• Vermis

• Infundibulum

• Substantia nigra

• Right hemisphere

• Flocculonodular lobe

Structures called __________ connect the cerebellum to the brainstem and allow communication between the cerebellum and other parts of the CNS.

• Vermis

• Funiculi

• Peduncles

• Commissure

The cerebellum functions as a comparator. This means that the cerebellum compares

• intended movements with actual movements.

• spinal cord activity with the activity of the cerebrum.

• the incoming sensory stimuli with the outgoing sensory stimuli.

• the right cerebellar hemisphere with the left cerebellar hemisphere.

Superior cerebellar peduncle

• Ridges of cerebellar cortex

• White matter of the cerebellum

• Connect the cerebellum to the pons

• Connect the cerebellum to the midbrain

Middle cerebellar peduncle

• White matter of cerebellum

• Ridges of cerebellar cortex

• Connect the cerebellum to the pons

• Connect cerebellum to medulla oblongata

Inferior cerebellar peduncle

• White matter of cerebellum

• Ridges of the cerebellar cortex

• Connect the cerebellum to the mid brain

• Connect cerebellum to medulla oblongata
