NEET PG DENTAL EXAM

Detailed explanation-1: -Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium . The axons are bundled together into groups called fascicles . Each fascicle is wrapped in a layer of connective tissue called the perineurium.

Detailed explanation-2: -The perineurium allows some movement of axons within the fascicles and maintains intrafascicular pressure while acting as an effective physical barrier against mechanical and chemical injury. The perineurium transmits pressure to the endoneurium, which then generates intracellular pressure within the axon.

Detailed explanation-3: -A connective tissue sheath called the epineurium surrounds each nerve. Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium.
