Purkinje cell

(pûr-kĭn′jē)
n.
A large, drop-shaped, densely branching neuron that is the characteristic cell of the cerebellar cortex.

Purkinje cell

A large cerebellar cortex neuron with an ornate, antler-shaped dendritic arbor. Purkinje cells receive inputs (climbing fibers) from the inferior olive, and they send their axons (inhibitory) to the cerebellar and vestibular nuclei.
Synonym: Purkinje neuron

Purkinje cell

a specialized NEURONE of the CEREBELLUM consisting of an axon, a large cell body and a single dendrite which is much branched, like a tree.

Purkinje

named after J.E. Purkinje, Bohemian anatomist (1787-1869).

Purkinje cell
neuronal cell bodies in the middle layer of the cerebellar cortex; characterized by a large, globose body and massive, branching dendrites but a single, slender axon.
Purkinje fiber
modified cardiac muscle fibers in the subendothelial tissue, concerned with conducting impulses through the heart.
P's image, Purkinje-Sanson images
in a normal eye, reflections of light off the surface of the cornea, anterior lens capsule, and posterior lens capsule. When viewed from different angles, can be used to localize intraocular opacities.
Purkinje network
a reticulum of modified muscle fibers in the subendocardial tissue of the cardiac ventricles.
