MEDICAL PHYSIOLOGY

Detailed explanation-1: -Hormones are chemical messengers secreted into blood or extracellular fluid by one cell that affect the functioning of other cells.

Detailed explanation-2: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released.

Detailed explanation-3: -The correct answer: Chemicals that serve as signals that elicit a response from target cells are called C. hormones. Hormones are secretion of endocrine glands and they are responsible for acting as signaling molecules to elicit a specific response.

Detailed explanation-4: -A hormone is a chemical substance made and secreted by one cell that travels through the circulatory system or the extracellular fluid to affect the activities of cells in another part of the body or another nearby cell.

Detailed explanation-5: -Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell.
