Motor Neuron Pillows

Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.

Light microscopy of motor neurons in spinal cord grey matter. The cell bodies of motor neurons show a central nucleus and peripheral cytoplasm (deep purple). In histologic sections processes of dendrites and an axon extend from each cell body. In humans one such axon may be a metre in length if supplying the foot. Tissue between the cell bodies is called the neuropil and is formed of intermingling dendrites, axons, capillaries and glial cells. Magnification x100 when narrow width printed at 10 cm.
