Auditory Hole Internal

The internal auditory opening (porus acusticus internus) is a small opening in the pyramids of the temporal bones that connects the middle ear to the inner ear. It is an important anatomical structure because the auditory ossicles of the middle ear pass through it, which transmit sound waves from the eardrum to the oval window of the inner ear.

The internal auditory opening has the shape of a triangle and is located on the posterior wall of the pyramid of the temporal bone. It is bounded on one side by the pyramid of the temporal bone, and on the other by the membrane that separates the inner ear and middle ear. Inside the internal auditory opening is the auditory ossicle, the malleus, which connects to the incus and stapes.

In addition, the internal auditory opening contains many blood vessels and nerves that provide nutrition and innervation to the auditory system. Some studies suggest that the auditory canal may be intrinsically linked to various medical conditions such as sensorineural deafness, balance problems and headaches. However, there is still no clear understanding of the role of the auditory opening in these diseases.

Thus, the internal auditory opening is an important element of the human hearing system. It transmits sound waves from the middle ear to the inner ear and supplies it with essential nutrients and nerve impulses. Knowledge of the anatomy and physiology of the auditory canal can help in understanding processes related to hearing and balance, as well as in developing new treatments for diseases associated with this system.
