Physiology of the nervous system

Neurons are diverse in shape and size. A typical neuron has a cell body (or soma) with bre-like processes called dendrites and axons emerging from it. e dendrites are branches that leave the cell body and receive information from adjoining neurons. e dendrites have knob-like extensions called dendritic spines. e cell body has an extensive system of rough endoplasmic reticulum containing basophilic granules (Nissl substance), which synthesize proteins. e dendritic spines, dendrites and soma receive information from other cells.
