Question

Choose the statement that correctly describes the structure or function of dendrites.

1) Transmit action potentials away from the cell body
2) Are thin extensions of the axon
3) Release neurotransmitters to initiate graded potentials in adjacent cells
4) Transmit graded electrochemical impulses toward the cell body

Answer 1

The correct description of dendrites is that they transmit graded electrochemical impulses toward the cell body, acting as receptors for nerve impulses from other cells.

Step-by-step explanation:

The statement that correctly describes the structure or function of dendrites is: Dendrites transmit graded electrochemical impulses toward the cell body. Dendrites are extensions of the cell body, and their primary function is to receive nerve impulses from other cells.

This setup allows a neuron to communicate with many other cells. This description is distinct from that of an axon, which is designed to transmit action potentials away from the cell body, and axon terminals, which release neurotransmitters to initiate graded potentials in adjacent cells.
