What is the function of Temporoparietalis muscle?
Temporoparietalis is a scalp muscle that arises on each side from an aponeurosis common to the auricularis muscle. It passes superiorly to insert into the galeal aponeurosis. Its action is to fix the galeal aponeurosis. The nerve to temporoparietalis is the temporal branch of the facial nerve.
What is the insertion of temporalis?
Attachments of Temporalis Muscle: Origin & Insertion Origin: (proximal attachments): Temporal lines, temporal fossa, and temporal fascia. Insertion: (distal attachments): Tip and medial surface of coronoid process of mandible.
What is the origin of the masseter muscle?
Masseter muscle
| Origin | Superficial part: maxillary process of zygomatic bone, Inferior border of zygomatic arch (anterior 2/3) Deep part: deep/inferior surface of zygomatic arch (posterior 1/3) |
|---|---|
| Innervation | Masseteric nerve of mandibular nerve (CN V3) |
| Blood supply | Masseteric artery |
| Function | Elevates and protrudes mandible |
What are the origins and insertions for the masseter and the temporalis What do you mean by origins and insertion quizlet?
Masseter: origin- tendinous aponeurosis of the zygomatic process of the maxilla, anterior 2/3rds of the lower border of the zygomatic arch; Insertion- ramus of the mandible Temporalis: origin- temporal fossa and temporal fascia; insertion- coronoid process and anterior ramus of the mandible.
What is the origin of Sternocleidomastoid?
Sternocleidomastoid Attachments It originates on the anterior surface of the manubrium, and the superior border and anterior surface of the medial third of the clavicle. The SCM converges into one point and inserts on the lateral surface of the mastoid process and the nuchal line of the occipital bone.
What is the function of temporalis?
The temporalis muscle is one of the muscles of mastication. It is responsible for both closing the mouth and retraction (posterior fibers).
What is the origin of the masseter muscle exercise 11?
The origin of the masseter muscle is the zygomatic arch. The zygomatic arch, also called the cheek bone or zygomatic process, is a bony arch that connects the temporal and zygomatic bones, which are located on the sides of the face/skull.

|---|---|
| Insertion | Modiolus, blends with muscles of upper lip |
