Endocrine and neuroendocrine: a chemical released by a specialized group of cells into the circulation and acting on a distant target tissue. Paracrine: chemical communication between neighboring cells within a tissue or organ. Autocrine: a chemical acts on the same cell Intracrine: a chemical acting within the same cell.

Functional chemical messengers in endocrine system Definition and characteristics Hormone secretion and transport Mechanisms of hormone actions Hormone
Definition of hormone o Hormone is bioactive chemical messenger released from endocrine cells, and carried by extracellular fluid or blood to target cells throughout the body. By binding to its receptor, hormone initiates multiple reactions

Characteristics of hormone ◆ Specificity Extracellular Receptor ligand fluid complex ◆ Signaling Membrane ◆ High effective Intracellular ○OO ◆ Cooperation OOOOOOOOOOOOOOOOoO One ligand is amplified into many intracellular molecules
Characteristics of hormone Specificity Signaling High effective Cooperation
