Temporal muscle
Temporal muscle
The Temporal muscle is one of the muscles of mastication. It is a broad, fan-shaped muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone.
Anatomy[edit | edit source]
The muscle originates from the temporal fossa and the deep part of temporal fascia. It passes medial to the zygomatic arch and forms a tendon which inserts onto the coronoid process of the mandible, with its insertion extending into the retromolar fossa posterior to the most distal molar tooth.
Function[edit | edit source]
The temporal muscle is a muscle of mastication and its role is to elevate the mandible (close the jaw) and retract the mandible.
Clinical significance[edit | edit source]
In temporal arteritis, the temporal muscle may be sore. It may be involved in jaw pain and headaches.
