Lecture 12

Question 1

Cerebellum

Answer 1

Deeply folded lobes with folia. Contain highest density of neurons in CNS. Unlike cerebral cortex, cerebellum cortex has 3 layers where white matter is deep to these including:

• Molecular: synaptic, pink outer layer
• granular matter: synaptic, dark purple
• Purkinje neurons: single row between molecular and granular layer,

Question 2

Granular layer neurons

Answer 2

send their axons into the molecular layer then the bifurcate to form parallel fibres. Synapse with Purkinje neurons.

Question 3

Purkinje neurons

Answer 3

Has soma and dendrites in molecular layer while axons travel to white matter via granular layer or down into deeper cerebellar nuclei where it synapses.

Question 4

Ependymal cells

Answer 4

Epithelial-like cells that line cerebral ventricles
