What are the location and function of the temporalis muscle?
The temporalis muscle is a fan-shaped muscle located at each side of the head/skull near the area of the temples. This muscle's action is to move the mandible up, back, and side-to-side. These movements allow the temporalis muscle to play an important role in biting and chewing food.
Where is the temporalis muscle located quizlet?
Temporalis Muscle Origin : Fan shape across the temporal fossa of the temporal bone. Temporalis Insertion : Into the coronoid process of the mandible and down the anterior border of the ramus.
What is the function of the temporal muscles?
Function. The function of the anterior and mid fibres of the temporalis muscle is to elevate the mandible. The posterior fibres of the temporalis muscle function to retract the mandible. It also contributes to side to side grinding movement.
Where does the temporalis muscle originate?
The origin of the temporalis muscle is along the surface of the lateral skull at the temporal line. The muscle inserts on the coronoid process of the mandible and is a powerful elevator of the mandible.
What causes tight temporalis?
What are the causes & diagnosis of Temporalis Tendonitis? stress, tooth grinding, direct trauma to the Temporalis muscle, excessive gum chewing. In rare cases a condition called Coronoid Process Hyperplasia may be the cause of Temporal Tendinitis.
Does the temporalis closes the jaw?
The temporalis elevates and retracts the jaw. The lateral pterygoid is the only muscle of mastication that actively opens the jaw. Unilateral action of a lateral pterygoid produces lateral movement in the jaw, usually performed in concert with the medial pterygoids.
What is the action of temporalis?
Temporalis. The temporal muscle, or temporalis muscle, is one of several chewing muscles that is necessary for crushing and grinding objects between the molars. Due to its location and frequent use, this muscle may be a primary focal point for a recurring condition known as “tension headaches.”
Where are the masseter muscles located?
The masseter muscle is a facial muscle that is located in the cheek area. It's a rectangular-shaped muscle that is divided into the deep portion and the superficial portion. The deep portion is the more muscular portion that connects to the mandible.
What causes temporal muscle pain?
What are the causes & diagnosis of Temporalis Tendonitis? stress, tooth grinding, direct trauma to the Temporalis muscle, excessive gum chewing. In rare cases a condition called Coronoid Process Hyperplasia may be the cause of Temporal Tendinitis.
What causes temporal muscle atrophy?
Atrophy of the superficial temporal fat pad—caused by ischemia, denervation, or displacement through dissection, disinsertion, or atrophy of the temporalis muscle caused by injury to the frontal branch of the facial nerve—may result in temporal hollowing.
How is the temporalis muscle attached to the skull and jaw?
It 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 mandibular molar. In other mammals, the muscle usually spans the dorsal part of the skull all the way up to the medial line.
What does the temporalis muscle connect?
The temporalis muscle inserts or attaches to the coronoid process and the ramus of the mandible.
How do I relax my temporalis?

masticatory muscles The temporalis muscle is a thin, fan-shaped muscle situated within the temporal fossa of the skull. Along with the medial pterygoid, lateral pterygoid and masseter muscles, it belongs to the group masticatory muscles.
What is the origin and insertion of the temporalis muscle?
