[The sensitive innervation of the proximal sesamoid ligament of the ox]

The Authors have studied the sensitive innervation of the proximal sesamoid ligament of the ox and have found capsulated corpuscles only. Among these receptors, besides Pacini and pacini-like corpuscles, Golgi Mazzoni's corpuscles, muscle spindles and Golgi's tendon organs with a typical structure, the Authors have been described, for the first time in the ox, corpuscles constituted by numerous Pacini collected by a single capsule. It must be pointed out that the muscle spindles are always supplied by an annulo-spiral termination which is centrally placed in the equatorial region. A vegetative innervation is also present in this ligament.
