Question

Which of the following is not a function of glial cells?

• A. Protection of neurons from pathogens
• B. Insulation of neurons
• C. Synthesising neurotransmitters for neurons
• D. Providing nourishment to neurons

Answer 1

The correct option is C

Synthesising neurotransmitters for neurons

Glial cells make up the bulk of nervous tissue and aid the neurons in their function. They help in the protection of the neurons against pathogens. They bring about insulation of the neurons by forming the myelin sheath. They also help in providing nourishment to the neurons by providing a close association between the blood vessels and the neurons. However, neurotransmitters are formed by the neurons themselves.
