Which of the following muscles attach to the mastoid process of the temporal bone?
Which of the following muscles attach to the mastoid process of the temporal bone?
The mastoid process is part of the temporal bone. It is the insertion for the sternocleidomastoid muscle. In fact it is this muscle that causes this landmark to develop.
What muscles attach to mastoid process?
The mastoid process serves for the attachment of the sternocleidomastoid, the posterior belly of the digastric muscle, splenius capitis, and longissimus capitis.
What is the mastoid process of the temporal bone?
The mastoid process is a pyramidal bony projection from the posterior section of the temporal bone. The superior border of the mastoid portion of the temporal bone articulates with the parietal bone.

Which features are found in the petrous part of the temporal bone?

- styloid process,
- stylomastoid foramen (external opening of the facial canal),
- jugular fossa,
- petrosal fossula, featuring. tympanic canaliculus,

Why does my mastoid bone hurt?
The bone behind your ear is called the mastoid bone, which is part of your skull. If this bone becomes painful and red, you may have a very serious infection called mastoiditis. Mastoiditis is more common in children but can occur in adults and is usually caused by an untreated middle ear infection.
Where is the temporalis muscle?
temporal fossa
The temporalis muscle attaches above to the bone and fascia in the temporal fossa, superior to the zygomatic arch, and below to the coronoid process of the mandible and along the mandibular ramus (Figure 6-17). The temporalis muscles primarily close the jaw while the middle fibers bilaterally retrude the mandible.
What are the two temporal bones?
The temporal bones are two major bones in the skull, or cranium. They help form the sides and base of the skull, where they protect the temporal lobe of the brain and surround the ear canal. The other major bones in the skull are: the two parietal bones that make up the top of the skull.
Why is temporal bone called temporal?
Etymology. Its exact etymology is unknown. It is thought to be from the Old French temporal meaning “earthly,” which is directly from the Latin tempus meaning “time, proper time or season.” Temporal bones are situated on the sides of the skull, where grey hairs usually appear early on.
