Chapter 5

Excitable Tissue and Bioelectric Signals

Abstract

This chapter focuses on bioelectricity, meaning the active electrical properties of biological tissue. Topics include basic cell physiology, action potentials, and neuron and axon transmission. Details are given on different receptors and how nerve signals are transferred.

In living tissue, important communication control is implemented by hormones and nerves. Hormones are slow broadcasting information carriers; nerves are quick prewired point-to-point information carriers. Some cells are not excitable, such as adipose, connective tissue, and blood. They are passive, not under nerve control, and only weakly polarized. However, ...
