Question

Quizplus · Accepted Answer

A neurotransmitter is a chemical messenger that travels across the synaptic gap to transmit a nerve impulse from a neuron to a target cell, such as another neuron, muscle cell, or gland cell. Hormones, on the other hand, are chemical messengers that are secreted by endocrine glands into the bloodstream to regulate the activity of distant target cells. Receptors are molecules on the surface of cells that bind to specific chemical messengers, such as neurotransmitters or hormones, and trigger a cellular response. Biotransmitter and electrolyte are not terms used to describe chemical messengers involved in nervous system function.
