The longitudinal canals of the cochlear shaft (canales longitudinales modioli, PNA, BNA, JNA) are a group of anatomical structures that are located in the human auricle. These channels play an important role in transmitting sound waves from the eardrum to the inner ear.
The longitudinal canals of the cochlear shaft consist of three main parts: the outer canal, the middle canal and the inner canal. The external canal is located on the outer surface of the auricle and connects the eardrum to the external auditory canal. The middle canal passes through the body of the auricle, where it connects with the inner canal. The internal canal is located inside the auricle and ends in the pyramids of the inner ear.
Each of these channels has its own function. The outer channel is responsible for transmitting sound waves from the external environment to the middle channel. The middle canal conducts sound waves to the inner canal, where they are transmitted to the hair cells of the inner ear, which convert sound vibrations into electrical signals.
An important aspect of understanding the anatomy of these canals is that they can be damaged by trauma or surgery. This can lead to disruption of sound wave transmission and hearing impairment. Therefore, it is important to know the anatomy of these canals when performing medical procedures and ear surgeries.
The longitudinal canals of the cochlea (Canales longitudinales canaliculi modioli) are vital structures of the human body that are located inside the middle ear cavity. Their importance for the functioning of the body is beyond doubt, so in this article we will look at their features, how they are formed and what functions they perform.
The longitudinal canals of the cochlea or canales longitudinales cochleae extend from the outer lateral wall to the septum of the base of the cochlea, having the name Caepedes longitudinales in the male body and Caepides longitudinales uterque in the female body. They are symmetrical structures located on both sides in both men and women.
The longitudinal canals of the cochlear shaft are called the neuromuscular system in the formation of the spindle of muscle contraction, and also pass inside the brain stem of humans and animals. At the same time, they perform many important functions, including regulating blood circulation, producing hormones and neurotransmitters, and maintaining communication between brain centers. Let us consider in more detail what functions the longitudinal channels of the Julita rod perform.
What are longitudinal channels? Longitudinal canals are a system of tubular structures located inside vertebrates that
