The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing , shouting, or thunder .

The stapedius muscle, the smallest skeletal muscle in the body, connects to the stapes and is controlled by the facial nerve; the tensor tympani muscle is attached to the upper end of the medial surface of the handle of malleus [2] and is under the control of the medial pterygoid nerve which is a branch of the mandibular nerve of the trigeminal ...
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
Also located in the middle ear are the stapedius muscle and tensor tympani muscle, which protect the hearing mechanism through a stiffening reflex. The stapes transmits sound waves to the inner ear through the oval window , a flexible membrane separating the air-filled middle ear from the fluid-filled inner ear.
The medial pterygoid nerve supplies the medial pterygoid muscle, tensor tympani muscle, and tensor veli palatini muscle (via the nerve to tensor veli palatini). [1] The tensor veli palati muscle is the only of the five paired skeletal muscles to the soft palate not innervated by the pharyngeal plexus. [citation needed]
Tensor tympani (innervated by the mandibular nerve of CN V) [8] Tensor veli palatini (innervated by the mandibular nerve of CN V) The tube is opened during swallowing by contraction of the tensor veli palatini and levator veli palatini, muscles of the soft palate. [1] The tensor veli palatini makes the largest contribution to active opening of ...
