Component | Latin | Description | ||
Head | capitulum mallei | large upper extremity of the bone, oval in shape | articulates posteriorly with the incus, being free in the rest of its extent | facet for articulation with the incus is constricted near the middle (consists of an upper larger and lower smaller part nearly a right angle with each other) opposite the constriction (lower margin of the facet projects in the form of a process, cog-tooth or malleus spur) |
Neck | collum mallei | narrow contracted part, just beneath the head | below it is a prominence | various processes are attached to the prominence |
Handle | manubrium mallei | connected by its lateral margin with the tympanic membrane | directed downward, medialward, and backward | decreases in size toward its free end, which is curved slightly forward, and flattened transversely. Medial side, near its upper end, is a slight projection, into which the tendon of the tensor tympani is inserted |
Anterior Process | processus anterior (Folii), processus gracilis | delicate spicule from the eminence below the neck | directed forward to the petrotympanic fissure | to which it is connected by ligamentous fibers |
Lateral Process | processus lateralis, processus brevis | a slight conical projection from the root of the manubrium | directed laterally, and is attached to the upper part of the tympanic membrane | attached by means of the anterior and posterior malleolar folds, to the extremities of the notch of Rivinus. |
