A Bundle of Nerve Fibers is Surrounded by a Layer

Question

A bundle of nerve fibers is surrounded by a layer of fibrous connective tissue called the
A)epineurium.
B)fascicle.
C)endoneurium.
D)neurilemma.
E)perineurium.

Accepted Answer

The perineurium is a layer of fibrous connective tissue that surrounds a bundle of nerve fibers, also known as a fascicle. The epineurium is a layer of connective tissue that covers multiple fascicles, while the endoneurium is a layer that surrounds individual nerve fibers. The neurilemma, also known as the Schwann cell sheath, is a layer of cells that forms around axons in the peripheral nervous system. Therefore, the correct answer is E, perineurium.
