Concept explainers
Interpretation:
The terms chemical messenger, target tissue and hormone receptor have to be explained.
Concept Introduction:
Chemical messengers: The vital function of body is controlled and coordinated by chemical messengers. Hormones and neurotransmitters are chemical messengers where hormones are released by endocrine systems to the blood whereas neurotransmitters are released by the nerve cells.
Receptors: Receptors is a molecule or a part of molecule which interacts with a neurotransmitter, a hormone or other molecules which are biochemically active so that a response is initiated in a target cell. If a hormone is interacted with the chemical messenger, then it is a hormone receptor.
A cell or a group of cells where the messengers regulate its activity are known as target tissue.
