Question

Quizplus · Accepted Answer

Both neurotransmitters and neurohormones are released by neurons, and they affect only cells with specific receptors. However, neurotransmitters act locally on nearby cells, while neurohormones travel in the bloodstream to target cells in distant parts of the body. Neither neurotransmitters nor neurohormones are produced by all cells.
