Professoraxons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.

What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
The insulating material produced by Schwann cells is known as what?
The insulating material produced by Schwann cells is known as myelin. Myelin forms a protective covering around nerve fibers, allowing for faster transmission of nerve impulses. This insulation is critical for proper functioning of the nervous system.
Why does the myelin sheath have gaps in it?
The gaps in the myelin sheath, known as Nodes of Ranvier, are necessary for the proper conduction of nerve impulses. They allow for a faster transmission of electrical signals along the axon by allowing the action potential to "jump" from one node to the next, a process called saltatory conduction. This increases the speed and efficiency of nerve impulse transmission.
Is myelin a connective tissue?
No, myelin is not a connective tissue. Myelin is a lipid-rich material that forms a protective sheath around nerve fibers in the central and peripheral nervous systems. It is essential for the proper functioning of the nervous system by insulating and speeding up the transmission of nerve impulses.
What tissue forms the inner lining of a hair follicle?
The inner lining of a hair follicle is formed by the inner root sheath, which is made up of epithelial tissue. This sheath helps to protect and nourish the growing hair shaft as it develops within the follicle.
