Explanation Dopamine is a produced in the brain and belongs to catecholamines family. When dopamine is released from the axon terminal and then released into the blood stream, then it acts as a neurohormone. As a neurohormone its function is to inhibit prolactin secretion from the pituitary gland...

Chapter 38.2, Problem 1BC

Summary Introduction

To determine:

When the molecule acts as neurotransmitter or neurohormone.

Introduction:

Neurotransmitters are chemical messengers that help in transmission of signals across the chemical synapse, like neuromuscular junction. The hormones that are secreted by the neuroendocrine cells in the blood are termed as neurohormones. Some neurohormones also act as neurotransmitters.
