IncusДЄs seen in the image, it is the next ossicle, which is attached with malleus on one side and with the stapes on the other side. And the other end is attached to the next ossicle called the incus. This is a hammer-shaped bone, which is attached to the tympanic membrane (pars tensa part). Three bones of the middle ear ( Anatomy and Physiology by Ross and Wilson) Malleus Three ear ossicles are found in a human, namely. It has three small bones called ear ossicles. The middle ear is a densely packed portion of the ear.

A closed room, with the tympanic membrane on one side and oval and round windows on another side, the only aperture of this chamber is situated at its base, called the Eustachian tube. In the above image, the region with a blue shade is in the middle ear.ДЄs we can see, it is the continuation of the tympanic membrane. These vibrations are transmitted to the inner ear ossicles that, in the course, help in hearing. It converts sound energy into mechanical energy in the form of oscillations. It is loose, reddish, and has malleal folds. The tympanic membrane has two basic partsДЄ) Pars tensa: It is quite stretched with an attachment of the head of the malleus bone.Д«) Pars flaccida. It is 9-10mm in height, 8-9mm in width, and 0.1mm in thickness, placed obliquely. The tympanic membrane acts as the barrier between the middle ear and the external ear. The concha of pinna leads to an вЂS-shaped canal that ends at the tympanic membrane.Д®ar structure showing External, middle, and inner ear ( Anatomy and Physiology by Ross and Wilson) C. The cartilage is used in reconstruction surgery of the middle ear or nasal bridge.

A perfect condensation of sound is achieved through this pinna.ДЇurther, the skin of pinna is used for grafting like nasal ala or of hands. ItвЂ™s an astonishing piece of art of nature that shows perfect engineering. It is a single piece of yellow cartilage tissue, except for the lower lobule part, which is barely a piece of flesh and skin.ДЇunctions of the pinna: Pinna acts as a condenser it collects the sound waves from distant sources and channels them onto the tympanic membrane. The structure of the pinna has cartilage covered up with skin. It cannot be moved in humans, but in lower animals, it can be moved, like in rabbits, dogs, cows, etc. Pinna is the outer helical structure that we can see on each side of the head. Structures: External, although it may seem devoid of many structures, also has a lot. The external earВ starts from the part of the ear we see, that protruding part, and is limited in the inner side by the tympanic membrane.
