Question

Quizplus · Accepted Answer

Neurotransmitters bind to specific receptor sites on neurons to exert their effects. Receptors play a crucial role in mediating the effects of hormones, neurotransmitters, and other ligands in the body. They can also be targets for drugs to either activate or inhibit their function. Neuromodulators, on the other hand, are endogenous ligands that can alter the sensitivity of receptors to their primary neurotransmitter. Hormone receptors are found in various tissues including the brain, and their distribution may vary depending on the specific hormone.
