Question

The perineurium is

B) another name for a fascicle
C) a thin wrapping of fibrous tissue around each axon
D) a thin fibrous tissue surrounding a group of axons

Accepted Answer

The perineurium is a thin fibrous tissue surrounding a group of axons, forming a fascicle. Option A is incorrect as it describes the epineurium, which is a tough, fibrous sheath covering the whole nerve. Option B is incorrect because a fascicle is a bundle of axons within a nerve, but not the same as the perineurium. Option C is incorrect as it describes the endoneurium, which is a thin wrapping of fibrous tissue around each individual axon.
