1. How Nerve Cells Work Nerve cells process and transmit information by electrical and chemical signalling. Chemical signalling occurs via synapses, in a process known as synaptic transmission. This is a process where the axon terminal of one cell impinges upon a dendrite or soma of another [or less commonly to an axon].
The brain sends messages through the spinal cord and nerves of the peripheral nervous system to control the movement of the muscles and the function of internal organs. The basic working unit of the nervous system is a cell called a neuron. The human brain contains about 100 billion neurons. A neuron consists of a cell body containing the nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz).
