Which part of the neuron directs the manufacture of substances that help the neuron grow?Multiple choice question.myelincell bodyaxondendrite

The part of the neuron that directs the manufacture of substances that help the neuron grow is the cell body (also known as the soma).

Explanation:

1. Cell Body (Soma): This is the central part of the neuron containing the nucleus. It is responsible for maintaining the life of the neuron and plays a crucial role in processing information. The cell body synthesizes proteins and other molecules necessary for the growth and maintenance of the neuron.

2. Dendrites: These structures receive signals from other neurons and play a role in transmitting these signals to the cell body, but they do not manufacture substances for growth.

3. Axon: The axon transmits electrical impulses away from the cell body to other neurons or muscles. While important for communication, it does not manufacture growth substances.

4. Myelin: Myelin is a fatty substance that surrounds the axon and helps speed up nerve impulse transmission, but it is not produced in the neuron itself – it’s produced by glial cells.

Final Answer:

The correct answer is cell body.
