Neurolemma
Neurolemma
Neurolemma (pronounced: /nʊərəˈlɛmə/), also known as the Schwann cell membrane or sheath of Schwann, is the outermost layer of the nerve fiber in peripheral nerves. The term is derived from the Greek words "neuron" meaning nerve and "lemma" meaning husk or peel.
Etymology
The term "neurolemma" was first used in the mid-19th century and is derived from the Greek words "neuron" (νεῦρον), meaning "nerve", and "lemma" (λῆμμα), meaning "husk" or "peel". This reflects the function of the neurolemma as a protective layer for the nerve fiber.
Function
The primary function of the neurolemma is to protect and insulate nerve fibers, facilitating the rapid transmission of nerve impulses. It also plays a crucial role in the regeneration of damaged nerve fibers in the peripheral nervous system.
