a) Myelin sheath provides an insulating layer to the dendrites.
b) The soma is the cell body of a nerve cell.
c) Axons carry the signal from the soma to the axon terminals.
d) Dendrites carry the signal to the soma."

Answer 1

Answer:

The true statements are B, C and D

Explanation:

Myelin sheet is a fatty substance that insulated the axons and speeds up transmission. It does not insulate the dendrites.

Axons is a long tail like stricture that joins the cell body also called as soma at a specialized junction called the axon hillock. Axon carry a single signal from the soma to the muscle fiber or to the next neuron whereas the dendrites carry signals from other neurons into the soma.

Dendrites are fiber like roots that branches out from the cell body.A dendrite like an antennae receive and process signals from the axon of one neuron to another neuron and meet at a synapse, which is a very narrow gap between the two cells.
