8. Eye
The abducens nerve is the sixth cranial somatic efferent nerve that controls the movement of the lateral rectus muscle of the eye
9. Occulomotor III
The oculomotor nerve is derived from the basal plate of the embryonic midbrain and innervates the muscle that controls papillary constriction
10. Na+ is higher inside and K+ is higher outside.
During depolarization, voltage gated Na+ channels open allowing Na to enter the cell. During repolarization, voltage gated K+ channels open allowing K to leave the cell.
11. Only on myelinated fibers
Saltatory conduction is the propagation of action potential from one nodes of ranvier to another in myelinated axons.
12. Cerebellum.
Arbur vitae is tge cerebellar White matter. It looks like the plant Arbor vitae with bushy dense branches. Hence got its name.
