2023年11月2日 · The masticatory muscles attach to the mandible, and thus produce movements of the lower jaw at the temporomandibular joint (TMJ) to enable functions such as chewing and grinding. These movements include:

2024年10月1日 · The muscles of mastication are associated with movements of the jaw (temporomandibular joint). There are four muscles: Masseter; Temporalis; Medial pterygoid; Lateral pterygoid; The muscles of mastication develop from the first pharyngeal arch. They are therefore innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.

The muscles of mastication originate on the skull and insert into the mandible, thereby allowing for jaw movements during contraction. Each of these primary muscles of mastication is paired, with each side of the mandible possessing one of the four.

The muscles of mastication are a group of muscles responsible for the chewing movement of the mandible at the temporomandibular (TMJ) joint, they enhance the process of eating, they assist in grinding food, and also function to approximate the teeth. The four main muscles of mastication originate from the surface of the skull and they attach ...

2023年6月5日 · The primary muscles of mastication (chewing food) are the temporalis, medial pterygoid, lateral pterygoid, and masseter muscles. The four main muscles of mastication attach to the rami of the mandible and function to move the jaw (mandible).

2020年3月12日 · Primary muscles of mastication: The most recognized group is composed of four muscles that function in pairs and are primarily responsible for TMJ function and mandibular movement.

2024年12月10日 · The muscles directly involved in the chewing process, which includes elevation, depression, protrusion, retrusion, and lateral movement of the mandible, are referred to as "masticatory" muscles (from the Latin masticatio – chewing, mastication). Functionally, these muscles work in opposition to the muscles responsible for opening the mouth.

2023年4月3日 · The muscles of mastication can be divided into primary and secondary groups according to whether they connect the mandible directly to the skull or if they attach to other structures in the neck, e.g. hyoid, thyroid cartilage. 3. Tomas X, Pomes J, Berenguer J et al. MR Imaging of Temporomandibular Joint Dysfunction: A Pictorial Review.

2019年10月4日 · Muscles involved in mastication include the masseter, temporalis, medial pterygoid, and lateral pterygoid. Mastication is step one of the digestion process. It breaks down food into smaller pieces so that it can be further digested by enzymes.

2023年11月2日 · The four basic masticatory muscles originate from the surface of the skull and relate to the mandible’s rami at the TMJ. Elevation, depression, protrusion, retraction, and side-to-side movement are all possible with these muscles.
