The Temporomandibular Joint and the Muscles of Mastication Muscles acting on the Temporomandibular Joint. 1  Movements of the temporomandibular joint are chiefly from the action of the muscles of mastication. 2  The temporalis, masseter, and medial pterygoid muscles produce biting movements.

Masseter Muscle - Function, Origin, Insertion & Innervation - Human Anatomy | Kenhub Anatomy and supply. The masseter muscle is a thick, rectangular muscle of mastication. It consists of a superficial and a deep part, both originating from the zygomatic arch.urthermore, part of the deep fibers radiates into the anterior capsule and articular disc of the temporomandibular joint. The parotid gland lies on the lateral side of the masseter with its duct coursing underneath the zygomatic arch across the muscle.

Muscles of Mastication Insertion: anterior surface of neck of mandibular condyle at pterygoid fovea, a few of most superior fibers insert on capsule of TMJ. Action: inferior head depresses mandible, main action when both muscles contract brings lower jaw forward. if only one lateral pterygoid muscle contracted, lower jaw shifts to opposite side (lateral deviation)

Masseter Muscle - Function, Origin, Insertion & Innervation - Human Anatomy | Kenhub Anatomy and supply. The masseter muscle is a thick, rectangular muscle of mastication. It consists of a superficial and a deep part, both originating from the zygomatic arch. The superficial part inserts on the masseteric tuberosity at the outer surface of the mandibular angle, whereas the deep part runs further dorsally to the outer surface of the mandibular ramus.

Muscles of Mastication The temporalis is a big fan shaped muscle that sits in the temporal fossa and inserts onto the coronoid process of the mandible. It elevates and retracts the mandible. The masseter sits over of the ramus, and angle of the mandible and acts to elevate the mandible.

- Temporal muscle. The temporal muscle, also known as the temporalis, 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.

Immediate effect of muscle energy technique on latent trigger point of upper trapezius muscle Immediate effect of muscle energy technique on latent trigger point of upper trapezius muscle. Objective The aim of this study was to investigate the immediate effect of muscle energy technique (MET) on latent myofascial trigger point (MTrPs) of the upper trapezius muscle. Methods Thirty-six female volunteers participated in this study. Subjects were divided randomly into 2 groups: MET and control groups.

The Muscles of Mastication They are one of the major muscle groups in the head – the other being the muscles of facial expression. There are four muscles of mastication – the masseter, temporalis, medial pterygoid and lateral pterygoid. Embryologically, the muscles of mastication develop from the first pharyngeal arch.Consequently they are innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.he entirety of the muscle lies superficially to the pterygoids and temporalis, covering them. 1  Attachments: The superficial part originates from maxillary process of the zygomatic bone. 2  Actions: Elevates the mandible, closing the mouth. 3  Innervation: Mandibular nerve (V 3).

Splenius Capitis Muscle Splenius Capitis Muscle. Introduction. The splenius capitis is one of the deep muscles of the back of the neck. It acts as an extensor of neck, lateral flexor and assists in rotation of the neck, and forms part of the floor of the posterior triangle of the neck. In this article we will discuss the gross and functional anatomy of the splenius capitis.

masseter muscle A muscle with origin from the inferior border and medial surface of the zygomatic arch, with insertion into the lateral surface of the ramus of the mandible, with nerve supply from the masseteric nerve, and whose action closes the jaw during chewing.

- Motor Component The efferent portion of the trigeminal nerve innervates the muscles involved in chewing. These include the temporalis, the masseter, the medial, and the lateral pterygoid. The trigeminal nerve also innervates the tensor veli palatine muscle, which tenses the velum.

The Muscles The temporalis muscle is one of the 4 muscles of mastication (so called as they are involved in the process of chewing). This is a fan-shaped muscle that originates at the inferior temporal line and passes behind the zygomatic arch to insert at the coronoid process and anterior sruface of the ramus of the mandible.

Masseter During chewing, the masseter is assisted by three other muscles: the temporalis, medial pterygoid, and lateral pterygoid. The four muscles work together to pull the jaw down and back up again.asseter. The masseter muscle is a facial muscle that plays a major role in the chewing of solid foods. The muscle is shaped similar to a parallelogram, connecting to the mandible (lower jawbone) and the cheekbone. The masseter is divided into two distinct sections, the superficial and deep portions.
