According to Gradenigo, the inner portion of the foot-plate is developedfrom the labyrinthine capsule, while the external part is derived from a ring-shaped deposit, which is situated laterally to the labyrinthine capsule. THE LIGAMENTS OF THE OSSICLES (?) The Ligaments of the Ossicles. Several ligamentous bands are still to be enumerated in addition to thosecapsular ligaments mentioned above; these extend between the walls of thetympanic cavity and the ossicles, retaining them in their position, and actingas check-bands in case of too great excursions. 1.
