STAPEDIUS Meaning and Definition

1. Stapedius is a noun that refers to a small muscle located in the middle ear. It is one of the smallest muscles in the human body and is named after its attachment to a small bone called the stapes, which is involved in transmitting sound vibrations from the outer ear to the inner ear. The stapedius muscle is housed within a bony canal and is positioned just above the opening of the inner ear, known as the oval window.

   The primary function of the stapedius muscle is to stabilize the stapes bone and dampen excessive vibrations. This helps to protect the delicate structures of the inner ear from loud, intense sounds. When exposed to a loud noise, the stapedius muscle contracts automatically, reducing the movement of the stapes bone and limiting the transmission of sound waves. This reflexive contraction is known as the stapedial reflex.

   The stapedius muscle is innervated by the seventh cranial nerve, also known as the facial nerve. Damage or dysfunction of this nerve can result in the impairment of the stapedius muscle, leading to a condition called stapedial paresis or paralysis. Symptoms of stapedial dysfunction may include increased sensitivity to loud sounds (hyperacusis) or difficulty tolerating certain frequencies of sound. Treatment options for stapedial dysfunction may include surgical interventions or the use of specialized hearing aids.

2. A small muscle in the tympanum inserted into the neck of the stapes.
