ANSWERS AND EXPLANATIONS




A) Basket cells

This answer is incorrect.


Basket cells do not give rise to parallel fibers. Basket cells are inhibitory interneurons in the cerebellar cortex. Their axons make "basket-like" arborizations around Purkinje cell bodies.  (See References)

B) Stellate cells

This answer is incorrect.


Stellate cells do not give rise to parallel fibers. Stellate cells are types of inhibitory interneurons. They receive input from parallel fibers, and synapse onto Purkinje cells.  (See References)

D) Granule cells

This answer is correct.


Cerebellar granule cells, the most abundant neurons in the human brain, give rise to parallel fibers. Parallel fibers rise to the molecular layer of the cerebellar cortex and make excitatory synapses with Purkinje cells.  (See References)

E) Mossy fibers

This answer is incorrect.


Mossy fibers are axons from afferent neurons outside the cerebellum. They do not give rise to parallel fibers.  (See References)
