What are climbing and mossy fibers? - Studybuff

Climbing fibers are the name given to a series of neuronal projections from the inferior olivary nucleus located in the medulla oblongata. These axons pass through the pons and enter the cerebellum via the inferior cerebellar peduncle where they form synapses with the deep cerebellar nuclei and Purkinje cells. Each climbing fiber will form synapses with 1-10 Purkinje cells. WebAs previously mentioned, the mossy fibers are 2.5 flm in diameter and the climbing fibers measure 1 flm in diameter. Afferent mossy and climbing fibers are additionally distinguished by their branching pattern as they enter the granular layer.

WebJun 16, 2014 · Unlike the mossy fibers and climbing fibers, the histaminergic afferent fibers, a third type of cerebellar afferents, extend fine varicose fibers throughout the cerebellar cortex and nuclei. Histamine receptors, belonging to the family of G protein-coupled receptors, are widely present in the cerebellum. WebIn contrast to mossy fibers and parallel fibers, each climbing fiber contacts only 10 Purkinje cells on average, making ~300 synapses with each Purkinje cell.
