The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
Its lateral edge corresponds with the remains of the petrosquamous suture. [1] The Atticus is the part of the tegmentum tympani where the stapes and incus are attached. The floor of the cavity (also called the jugular wall) is narrow, and consists of a thin plate of bone (fundus tympani) which separates the tympanic cavity from the jugular ...
Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates. Sutures are found in animals with hard parts from the Cambrian period to the present day. Sutures were and are formed by several different methods, and they exist between hard parts that are made from several different materials.
Your ears are responsible for more than just hearing; they keep you balanced, control facial features and help your taste, thanks to what's inside.
This bone is connected to the oval window by its annular ligament, which allows the footplate (or base) to transmit sound energy through the oval window into the inner ear. The stapes is the smallest and lightest bone in the human body , and is so-called because of its resemblance to a stirrup ( Latin : Stapes ).
Inside our ears is a complex structure that helps us balance, control facial features, and it even plays a major role in our taste. There’s a lot more going on inside your ears than first meets ...
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth , in humans making 2.75 turns around its axis, the modiolus . [ 2 ] [ 3 ] A core component of the cochlea is the organ of Corti , the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in ...
The ossicular chain is housed in a slender, air-filled cavity within the temporal bone and plays a pivotal role in hearing by amplifying and transmitting sound vibrations. [ 1 ] The primary function of the ossicular chain is to transmit sound vibrations from the external ear to the inner ear, where they are converted into electrical signals for ...
