Musculo-Tubal Channel

The myotubal canal is an anatomical structure that is a canal in the skull bone that connects the tympanic cavity to the nasopharynx. It passes through the petrous part of the temporal bone and is about 2 cm long.

The myotubal canal contains two muscles - the lateral pterygoid and medial pterygoid muscles. The contraction of these muscles regulates the air pressure in the tympanic cavity and also opens and closes the connection between the tympanic cavity and the nasopharynx. Thus, the myotubal canal plays an important role in the functioning of the auditory tube and sound transmission.

In addition to the muscles, the auditory tube passes through the muscular-tubal canal, connecting the tympanic cavity and the nasopharynx. The auditory tube serves to equalize the pressure on both sides of the eardrum.

Thus, the myotubal canal is an important anatomical structure involved in the regulation of pressure in the middle ear and ensuring the normal functioning of the auditory system.

The muscular-tubular canal (Latin: Canalis Musculotubaris; English: Muscular-Tubular Canal), or interosseous tubular canal, is a unique structure of the human body that has a common origin with intermuscular septa. It is located in the forearm and is formed by two groups of flexor and extensor muscles, which together perform the function of flexion and adduction of the limb. The length of the canal is about 20 cm from the intersection of the medial and lateral epicondylar lines to the lateral epicondyle of the humerus. B muscular
