This artery supplies branches to the medial pterygoid muscle, upper head of the lateral pterygoid, tensor veli palatini, parts of the sphenoid bone, middle cranial fossa, braches of mandibular division of the trigeminal nerve, and the otic ganglion.
The masseter muscle covering the lateral side of the joint was composed of three sections; the temporal muscle covering the cranial side of the joint was composed of one section; the lateral pterygoid muscle covering the medial part was made up of two sections; and the medial pterygoid muscle which didn't surround the joint was also made up of two sections.
In dog and cat, the zygomatic gland is located in the orbital cavity and its limits are determined by the zygomatic arch laterally and dorsally by the periorbital cavity, ventrally by the orbital fat and by the pterygoid muscle, and medially by the maxilla, which contains the roots of the last upper molar tooth (PEDINI et al.
Laughlin showed how simple maneuvers such as "internal pterygoid muscle release" can be done quickly in-office, providing greater comfort for patients with limited jaw opening, headaches, odd visual difficulties, even endocrine imbalances.
23) In sum, studies have demonstrated that the lateral pterygoid muscle has an effect on the growth of the condylar process, (24) the masseter muscle has an effect on the angular process, (16) and the temporal muscle has an effect on the growth of both the coronoid process (5) and the entire mandibular ramus and body, as demonstrated.
