  • Tensor tympani originates in the cartilaginous part of the auditory tube (eustachian tube) and the walls of its hemi-canal immediately above the bony portion of the auditory tube, and inserts on the handle of malleus. Action: drawing the handle of the malleus medialward, tensing the tympanic membrane to protect it from excessive vibration by loud sounds. Nerve supply: branches of the trigeminal nerve through the otic ganglion. Synonym: musculus tensor tympani, tensor muscle of tympanic membrane, Toynbee's muscle.
