Document Summary

16. 1 | the endocrine system is one of the body"s two major. There are four methods of cell-to-cell communication through electrical or chemical signals: gap junctions, contact dependent signals, local communication, long-distance communication. Definition of electrical signals, chemical signals; gap junctions, contact-dependent signals, paracrines, autocrines signals, long-distance communication. Chemical signals; molecules secreted by cells into the extracellular fluid. Gap junctions are for transfer of electrical and chemical signals (ions, small molecules-amino acids, atp, camp) Contact-dependent signals, (required interaction between membrane molecules on two cells. requires cams (cell adhesion molecules)) Paracrines locally acting chemicals that affect types of cells different from those that secrete them. Autocrines signals chemicals that exert effects on same cells that secrete them. The nervous system and the endocrine system regulate long distance communication among body cells. the nervous system fires action potentials that cause the release of neurotransmitters, the endocrine system secretes hormones.
