WebbPeripheral nerve. These longitudinally sectioned, peripheral nerve fascicles are each immediately surrounded by a perineurium which appears as a highly compact covering. The epineurium, between the fascicles, also surrounds the entire nerve and consists of dense connective tissue. It contains adipocytes as well as blood vessels that supply the ... The perineurium is a protective sheath that surrounds a nerve fascicle. This bundles together axons targeting the same anatomical location. The perineurium is composed from fibroblasts. In the peripheral nervous system, the myelin sheath of each axon in a nerve is wrapped in a delicate protective sheath … Visa mer The perineurium is composed of connective tissue, which has a distinctly lamellar arrangement consisting of one to several concentric layers. The perineurium is composed of perineurial cells, which are epithelioid Visa mer The perineurium, as the epineurium, has a clinical importance following a trauma, like a fracture.
