Temporalis

Pointer Plus The Pointer Plus is an easy to use trigger point (TP) locator which incorporates a push button stimulation feature to immediately treat Trigger point pain.

The Temporalis is a cranial muscle.

Anatomical Attachments:

• Origin: Attaches to the temporal fossa and the temporal fascia, superior to the zygomatic arch.
• Insertion: Attaches to the coronoid process and also to the anterior border of the ramus of the mandible.

Action: This muscle of mastication elevates and closes the jaw and retracts the mandible.

Synergist: Masseter, Superior division of the lateral Pterygoid and the medial Pterygoid.

Antagonist: Inferior divisions of the lateral Pterygoid, anterior Digastric, Omohyoid, and Mylohyoid.

Nerve Supply: Trigeminal nerve (Cranial nerve V).

Vascular supply: Anterior and posterior deep temporal artery, as well as the superficial temporal artery.

• Primary: The pain refers throughout the temple, along the eyebrow, behind the eye and upper teeth, and in some cases it may refer to the maxilla and the temporomandibular joint.
• Satellite or associated triggers: Ipsilateral masseter, Medial and Lateral Pterygoid, Upper Trapezius, Sternocleidomastoid.
