ur body is built with biological tissue. The tissue that can generate or detect bioelectrical signals is called excitable tissue. Some examples of this tissue (and its cells) are: neurons and muscular tissue. Neurons are responsible of transmitting the excitatory bioelectrical signal to another neuron (forming nerves) or to a muscle tissue, gland or brain, while muscular cells are responsible of muscular contraction and distension. Some specialized cells generate bioelectric signals: optic receptors (eyes), muscular cells that transmit the feeling of pain, etc.Bioelectricity concerns the magnetic and electrical fields produced by organisms or cells.u
1. The neuron
The neuron can be divided in three main parts: Dendrites, Soma, Axon (Figure 1). Dendrites are prolongations of the soma in shape of trees (dendros in Greek) and they receive most of the excitatory signals. The soma contains the nucleus of the cell and is where most of the proteinic synthesis occurs. The Axon is a prolongation of the soma and is responsible of the synapse (mechanism of transmit in the excitatory signal to another cell).
