![]() It is located between the malleus’s neck and the lateral process, attaching to the middle ear at the anterior wall. The anterior and posterior malleolar folds hold this lateral projection in its place where it attaches to the upper part of the eardrum.Īnterior process (Rau’s/Folian process): Another cone-shaped projection, it is much longer and more pronounced than the lateral process. Lateral process: It is the small cone-shaped projection at the base of the manubrium. The small projection on its medial wall serves as the point of insertion for the tensor tympani muscle. ![]() The manubrium’s lateral wall connects with the tympanic membrane. Manubrium (Handle): This is the most notable landmark of the malleus, extending downwards as it curves and narrows towards its tip. Inferior to it is a bony prominence where the malleus’s processes attach. Neck: It is the narrow region just below the head, lying on top of the flaccid portion of the tympanic membrane, the pars flaccida. Head: It is the oval, saddle-shaped posterior surface of the bone that articulates with the incus, forming the incudomalleolar joint, which is a synovial joint. This is how sound makes its way to our brain for us to hear and make sense of it AnatomyĪs mentioned above, this bone resembles a hammer in shape, having a head, neck, and multiple essential processes and landmarks. So, its primary function is to transfer these sound vibrations from the tympanic membrane to the incus so it can be sent on to the inner ear through the stapes and oval window. ![]() ![]() It is the first ear ossicle to move when a sound vibration reaches the tympanic membrane. ![]()
