2023年5月25日 · The mastoid process is easily palpable just behind the ears. It serves as the insertion site of many muscles in the head and neck region. In addition, it contains air-filled spaces called the mastoid air cells. This article will discuss the gross and functional anatomy of the mastoid process.

The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones.

2023年6月21日 · The mastoid process is a bony projection on the temporal bone—located behind your ears on each side of your skull. Due to its location, ear issues—such as a middle ear infection—can cause pain at the mastoid process. This bone also provides an attachment point for several muscles.

2023年1月9日 · Gross anatomy. An irregular cavity within the anterosuperior aspect of the bone is called the mastoid (or tympanic) antrum, which communicates with the attic of the tympanic cavity 1. Pneumatization extends from the antrum as the mastoid air cells.

2017年10月24日 · The mastoid process anatomy comprises complex structures. It is located behind the ear, and is known as the C1 bone of the spinal vertebral level. The mastoid process bone itself is in the shape of a pyramid that projects behind the temporal bone.

2020年10月18日 · The mastoid process is a smooth conical projection of bone located at the base of the mastoid area of the temporal bone. It allows the attachment of muscles such as the occipitofrontalis muscle, as well as certain muscles of the neck like the sternocleidmastoid and splenius capitis muscles.

2024年10月7日 · Explore the anatomy, development, and auditory functions of the mastoid process in this comprehensive overview. The mastoid process, a bony prominence located behind the ear, plays an essential role in human anatomy and auditory function.

2015年12月29日 · The mastoid portion contains the mastoid air cell system, articulates laterally with the parietal and occipital bones, and communicates with the nasopharynx via the eustachian tube. There is contiguity of the mastoid air cells and those of the petrous pyramid (petrous apex).

2023年3月10日 · The mastoid process is a significant cone-shaped projection from the bottom of the skull, situated just behind the ear opening–the external acoustic meatus –and positioned posterolateral to the styloid process. It points downward and forward.

The mastoid part is the posterolaterally located, thick portion of the temporal bone. It is continuous: —anteromedially, with the petrous part; —anteriorly, with both the squamous and tympanic parts. The mastoid part consists of: —two surfaces (internal and external); —two borders (parietal and occipital); —a mastoid antrum and air cells;
