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.
