Purkinje nerve cells. Light micrograph of a row of Purkinje nerve cells from the cerebellum of the brain. Each Purkinje cell is composed of a flask-shaped cell body, from which branch numerous dendrites (left frame). Purkinje cells are arranged between the junction of the molecular and granular layers of the cerebellum. Nerve impulses flow to the Purkinje cells through their dendrites. From here the message is passed on to the white matter deep in the cerebellum. The cerebellum is the largest part of the hindbrain, and is essential for the maintenance of muscle tone, balance, and muscle coordination. Magnification: x 200 at 10cm.
