Stapedius muscle and tensor tympani
WebbContraction of the stapedius and tensor tympani muscles are integral parts of the acoustic reflex, defined as consensual, reflexive contraction of the muscles in response to stimuli (typically high-energy sound pressure) that leads to attenuated acoustic transmission. The tensor veli palatini muscle arises from a groove in the petrous portion ... The tensor tympani is a muscle that is present in the middle ear. It arises from the cartilaginous part of the auditory tube, and the adjacent great wing of the sphenoid. It then passes through its own canal, and ends in the tympanic cavity as a slim tendon that connects to the handle of the malleus. The tendon makes a sharp bend around the processus cochleariformis, part of the wall of its cavity…

Webb13 juli 2024 · Function. The small stapedius muscle plays a crucial role in your ability to hear. Its main function is to stabilize the stapes bone, the smallest bone in your body. The middle ear’s job is to facilitate the movement of sound waves from the outer ear to the inner ear. This chain of events is set in motion as you hear sounds.

Webb7 feb. 2024 · Activity of either the stapedius or the tympani tensor muscles can dampen the amplitude of sounds by about 20-30 decibels. In some cases, an injury to the nerves that innervate these two muscles may result in a hearing disorder called hyperacusis. In hyperacusis, sounds are much louder than they would be in normal conditions.
WebbThe tensor tympani muscle originates rostrally and medially from the bony recess in the petrous portion of the temporal bone and makes its tendinous insertion onto the muscular process of the neck of the malleus (Fig. 20-16; see Fig. 20-13, A).
