Question

_____ ______ ______ is the ability of the axon wall and myelin insulation to prevent diffusion of intracellular fluid out of the axon to provide faster processing speed.

(write the full name of the term - 3 words)

Answer 1

Myelin sheath integrity refers to the insulation capability of the myelin sheath surrounding axons, ensuring efficient and rapid signal transmission through saltatory conduction.

Step-by-step explanation:

The term you are looking for is myelin sheath integrity. This term describes the ability of the axon's myelin sheath to act as an insulator, preventing the diffusion of intracellular fluid out of the axon and allowing for faster processing speeds.

The myelin sheath is a lipid-rich layer produced by glial cells, such as oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS). It is crucial for efficient nerve conduction as it facilitates saltatory conduction, which is the rapid propagation of action potentials along a myelinated axon. The action potentials ‘jump’ from one node of Ranvier to the next, where the axon membrane is exposed and regeneration of the signal occurs, allowing for faster transmission with less energy consumption and reduced signal loss.
