Are internodes the gaps in myelin along the axon?

No, internodes are not the gaps in myelin along the axon; they refer to the segments of the axon that are covered by myelin sheaths. The gaps between these myelinated segments are called nodes of Ranvier. These nodes play a crucial role in the conduction of nerve impulses, allowing for faster transmission through a process called saltatory conduction.


What role does myelin have in regulating speed?

Myelin is a white, phospholipid covering that is found on axons in the body. When it comes to nerve impulses, this covering does not conduct an electric current. Instead nerve impulses "jump" from one neurofibral node to another speeding up conduction of the impulse.


What kind of a coating do axons have?

Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.


Describe the role of the myelin sheath?

Myelin sheath is the insulation of the CNS (central nervous system). Its helps electrical signals move along nerves. Basically, its synonymous with insulated wire. Again the insulation help the signal move in a smooth and controlled fashion through out the body.

Is IVIG used to treat the repair of the myelin on nerves?

Intravenous immunoglobulin (IVIG) is not primarily used to repair myelin on nerves, but it can play a role in treating certain autoimmune conditions that affect myelin, such as Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy (CIDP). IVIG works by modulating the immune system, helping to reduce inflammation and potentially aiding in the recovery of nerve function. While it may support the healing process, it does not directly promote myelin repair.


What does myelin cause your body to have?

Myelin is a fatty substance that surrounds nerves and helps facilitate the rapid transmission of electrical impulses. It helps to speed up and enhance the efficiency of nerve signal transmission in the body. The presence of myelin is crucial for proper nerve function and the coordination of various bodily processes.

What plays a role in your body type?

Genetics play a significant role in determining body type, influencing factors such as muscle mass distribution and metabolism. Diet and exercise habits also play a role in shaping body composition over time. Hormones, such as cortisol and insulin, can also impact body type and fat distribution.
