title: On the collateral sesamoidean (suspensory navicular) ligament of equines: topographic relations and sensitive innervation.
abstract: The origin and course of the collateral sesamoidean (suspensory navicular) ligament of the horse and ass and its attachment to the distal sesamoid bone were studied by means of dissection. Particular attention was given to the topographic relations between this ligament and the deep digital flexor tendon. Numerous sensitive nerve endings are present in this anatomical district. The free and encapsulated nerve endings, displayed by impregnating techniques, are mostly concentrated in the ligament tract connected to the above-named tendon and close to its attachment to the distal sesamoid angle. The nerve endings are identified as typical Pacini, Pacini-like and Golgi-Mazzoni corpuscles on account of their morphological features and are found isolated, grouped to form flower-sprays, lined up along the course of a single nerve fibre or grouped to originate poikilomorphous fibres.
