The mastoid process anatomy comprises complex structures.

Ear bones anatomy. These bones play an important role in the sense of hearing by transmitting sounds to the inner ear. The inner ear has two main parts. The ear is divided into three parts.

The middle ear contains three bones the malleus incus and stapes that amplify the sound. Ear bone also called auditory ossicle any of the three tiny bones in the middle ear of all mammals. The inner ear also called the labyrinth.

Mastoid process bone behind the ear. It is located behind the ear and is known as the c1 bone of the spinal vertebral level. The spiral shaped cochlea is part of the.

The smallest bone in the body. The bones of the ear also known as the auditory ossicles are the three smallest bones in the human body. The outer ear gathers sound and allows it to pass through the ear canal to the eardrum.

The ossicles directly couple sound energy from the ear drum to the oval window of the cochlea. Stapes or stirrup the footplate. Together they form a short chain that crosses the middle ear and transmits vibrations caused by sound waves from the eardrum membrane to the liquid of the inner ear.

Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate and the vibrations are conducted to the nearby cochlea. The middle ear contains the three small bonesthe ossicles involved in the transmission of sound and is connected to the throat at the nasopharynx via the pharyngeal opening of the eustachian tube. The middle ear contains three tiny bones known as the ossicles.

Three tiny bones the malleus incus and stapes within the middle ear transfer sound. The mastoid process bone itself is in the shape of a pyramid that projects behind the temporal bone. The ossicles were given their latin names for their distinctive shapes.

They are also referred to as the hammer anvil and stirrup respectively. Ear anatomy inner ear next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear.
