cerebellam
Term
what are the two receptors of the cerebellar pathways
Definition
annulospiral and flower spray (intrafusal muscles)
Term
associated with an intrafusal muscle fiber, that is stimulated by a stretch impulse resulting from the extension of a muscle. The ending is in the form of a gradual spiral around the length of the intrafusal muscle fiber in the muscle spindle and is connected to the coarse myelinated fibers.
Definition
annulospiral
Term
sensory nerve ending that is attached to the distal end of an intrafusal muscle fiber and that is stimulated when the muscle fiber contracts, pulling on the nerve ending.
Definition
flower spray
Term

ICP to the ipsilateral cerebellum via climbing fibers
Term
the ventral spinocerebellar tract goes to the
