What is the primary function of lipids coated around nerves?
Understand the Problem
The question is asking about the primary function of lipids that are found around nerves, particularly in the context of their biological role. We need to identify which option best describes this function.
Answer
Insulation and rapid transmission of nerve impulses.
The primary function of lipids coated around nerves is to form the myelin sheath, which insulates neurons and allows electrical impulses to transmit quickly and efficiently along the nerve cells.
Answer for screen readers
The primary function of lipids coated around nerves is to form the myelin sheath, which insulates neurons and allows electrical impulses to transmit quickly and efficiently along the nerve cells.
More Information
The myelin sheath, composed primarily of lipids, is vital for the proper functioning of the nervous system. It enables faster transmission of electrical signals along the neurons and helps with efficient communication between nerve cells.
Tips
A common mistake is confusing the insulating function of lipids with energy storage in the context of nerve cells. However, their role here is structural and functional in terms of signal transmission.
