From its borders the mastoid part articulates with two other bones.

Mastoid anatomy. The mastoid is the portion of the petrous temporal bone that lies superior to the middle ear cavity. The mastoid part of the temporal bone is the back part of the temporal bone. The mastoid process anatomy comprises complex structures.

It is one of the two projections situated behind the ear. The mastoid is filled with a system of interconnecting air filled cells. The mastoid process bone itself is in the shape of a pyramid that projects behind the temporal bone.

It is located behind the ear and is known as the c1 bone of the spinal vertebral level. The sternocleidomastoid muscle rotates the head to the contralateral side. The mastoid process itself the pointed projection gives rise to.

Its rough surface gives attachment to various muscles and it has openings for the transmission of blood vessels. The mastoid process provides an attachment for certain muscles of the neck. Mastoid process anatomy the mastoid process is a pair of conical bones projecting downwards arising from the posterior ends of the parietal bones of the skull.

The splenius capitis muscle extends rotates and laterally flexes the head. The mastoid process is located in the posterior portion of the temporal bone. The parietal bones are a pair of bones present on each of the lateral walls of the skull encompassing the middle and the inner ear.

The mastoid antrum serves as an open canal between the middle ear and mastoid air cells fig.
