The outer covering of an axon is primarily composed of a myelin sheath, which is formed by glial cells. In the peripheral nervous system, Schwann cells create this myelin, while in the central nervous system, oligodendrocytes perform the same function. The myelin sheath is segmented by nodes of Ranvier, which facilitate faster signal transmission through saltatory conduction. Additionally, the axon is surrounded by a layer called the endoneurium, which provides structural support.

What is the tissue that makes up the outer covering in humans?
The tissue that makes up the outer covering in humans is called the epidermis. It is the outermost layer of the skin and serves as a protective barrier against environmental factors. The epidermis also contains cells that produce melanin, which gives skin its color and helps protect against UV radiation.
Tissue that makes up the outer covering of humans?
The tissue that makes up the outer covering of humans is called epithelial tissue. It forms the skin, as well as the lining of various organs and cavities in the body. Epithelial tissue serves as a protective barrier and helps regulate the exchange of materials between the body and its environment.
What is the outer covering of crocodile?
Crocodiles have tough, scaly skin on their outer covering that helps protect them from their environment and predators. This skin is made up of keratin, the same protein that makes up human fingernails and hair. Crocodile skin also helps them regulate their body temperature and stay hydrated.
What is the outer covering of the brain is made up of what?
The outer covering of the brain is called the meninges. It is made up of three layers: the dura mater, arachnoid mater, and pia mater. These layers provide protection and support for the brain and spinal cord.
Is hair the outer covering of a seal?
No, hair is not the outer covering of a seal. Seals have a thick layer of blubber under their skin, and their outer covering is made up of a combination of thick, waterproof fur or hair. This fur helps seals regulate their body temperature and stay warm in cold water.
What is the name for the insulation covering many neurons?
Myelin sheath. This is the insulating sheath which covers most of the axon, between the Axon Hillock and Collateral branches of the Neuron.
What purpose does the myelin covering an axon serve?
Myelin acts as an insulating layer around the axon, allowing for faster transmission of electrical impulses. It helps to speed up nerve conduction and prevents signal loss by reducing interference between neighboring nerve fibers.
