What Do We Call The Small Spaces Within The Myelin Sheath. Myelination is the formation of a myelin sheath. The myelin sheath exists in sections called internodes. The myelin membranes originate from and are a part of the. The myelin sheath is a greatly extended and modified plasma membrane wrapped around the nerve axon in a spiral fashion. It consists of concentric layers of myelin, formed in the peripheral nervous system by the plasma. In degenerative nerve diseases, the myelin sheath is lost and it produces a number of symptoms. Many of these symptoms can progress to paralysis and death. To understand myelination, we must first understand the cellular structure of the nervous system. Why can some organisms exist with no myelin sheath, and still function? This article will discuss the structure and histology of myelin sheaths, their function, and the process of brain myelination. The myelin sheath is the cylindrical covering on the axons of some neurons; The minute gaps that occur between adjacent myelin sheaths are called nodes of ranvier. These nodes contain positive sodium ions, which help recharge the electrical signals as they jump from one node to another. Between each internode are small spaces known as nodes of ranvier. Whilst the myelin sheath wraps around the axons, there are some small, uncovered gaps between the myelin sheath, called the nodes of ranvier.

Why can some organisms exist with no myelin sheath, and still function? These nodes contain positive sodium ions, which help recharge the electrical signals as they jump from one node to another. In these areas, the axon is exposed to the surrounding environment and proteins embedded in the plasma membrane can produce action potentials (electrochemical impulses). In degenerative nerve diseases, the myelin sheath is lost and it produces a number of symptoms. Myelination is the formation of a myelin sheath. Many of these symptoms can progress to paralysis and death.
