NEET PG DENTAL EXAM

Detailed explanation-1: -Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium. Within the fasciculus, each individual nerve fiber, with its myelin and neurilemma, is surrounded by connective tissue called the endoneurium.

Detailed explanation-2: -CONNECTIVE TISSUE SHEATHS OF PERIPHERAL NERVES Surrounding every fascicle within the nerve is the perineurium. Individual nerve fibers within the fascicles are embedded in endoneurium, which fills the space bound by the perineurium.

Detailed explanation-3: -Perineurium isolates groups of axon-Schwann cell units to form nerve fascicles and constitutes the main diffusion barrier between the endoneurium and the extrafascicular tissues.
