MICROANATOMY

Detailed explanation-1: -In order to detect a signal (that is, to be a target cell), a neighbor cell must have the right receptor for that signal. When a signaling molecule binds to its receptor, it alters the shape or activity of the receptor, triggering a change inside of the cell.

Detailed explanation-2: -How Do Cells Recognize Signals? Cells have proteins called receptors that bind to signaling molecules and initiate a physiological response. Different receptors are specific for different molecules.

Detailed explanation-3: -Reception: Reception is when the cell detects a signaling molecule from the cell’s extracellular matrix. This signal then binds to its specific receptor and causes a change in the protein receptor shape.

Detailed explanation-4: -The number of receptors that respond to a hormone determines the cell’s sensitivity to that hormone, and the resulting cellular response. Additionally, the number of receptors that respond to a hormone can change over time, resulting in increased or decreased cell sensitivity.
