Question

1.Identify the cell that myelinates axons within the spinocerebellar fiber tracts.

fibrous astrocyte or   oligodendrocyte

2. Identify the peduncles through which paired spinocerebellar tracts enter the cerebellum.

superior peduncles or inferior peduncles

3. The brainstem is linked to the cerebellum via 3 pairs of peduncles. In spite of this name, a peduncle is simply a large

a. nerve b. fiber tract

4. Neurons within the cerebellum are organized as

deep nuclei or   deep nuclei and a cortex

5. Sensory input from the global population of proprioceptors is integrated within the cerebellar cortex. Which region?

spinocerebellum or   vestibulocerebellum

Explanation / Answer

1. The cell that myelinates axons within the spinocerebellar fiber tracts are oligodendrocytes.

2. The peduncles through which paired spinocerebellar tracts enter the cerebellum are inferior peduncles.

3. The brainstem is linked to the cerebellum via 3 pairs of peduncles. In spite of this name, a peduncle is simply a large fiber tract.

4. Neurons within the cerebellum are organized as deep nuclei and a cortex.

5. Sensory input from the global population of proprioceptors is integrated within the cerebellar cortex. That particular region is spinocerebellum.
