Purkinje nerve cells. Light micrograph of a section through a row of Purkinje nerve cells from the brain's cerebellum. Each Purkinje cell is composed of a flask-shaped cell body which branch numerous dendrites. 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 cerebellar cortex. The cerebellum, the largest part of the hindbrain, controls balance, posture and muscle coordination. Cajal stain, dark field lighting. Magnification: x150.
