It can also describe a type of infection that is able to penetrate the blood-brain barrier and move into the brain, causing neurological symptoms such as seizures, meningitis, or encephalitis.
Neurolemma
Neurolemma refers to the outermost layer of a peripheral nerve, which is a type of nerve that connects the central nervous system (brain and spinal cord) to peripheral parts of the body, such as muscles and organs. The neurolemma is a layer of Schwann cells that surrounds the axons of nerve fibers, insulating and protecting them as they transmit nerve impulses. It is often referred to as the myelin sheath, as Schwann cells produce a fatty substance called myelin that wraps around the axons. The neurolemma plays a crucial role in maintaining the health and function of peripheral nerves.
Neurolemmocyte
A neurolemmocyte, also known as an oligodendrocyte, is a type of glial cell found in the central nervous system (CNS) of vertebrates. Its main function is to form the myelin sheath around the axons of neurons, providing electrical insulation and facilitating the transmission of nerve impulses. Without myelination, nerve impulses would not propagate efficiently, and the conduction of electrical signals would be slow and unreliable.
