What are various muscles assisting in mastication?

The muscles of mastication are a group of muscles that consist of the temporalis, masseter, medial pterygoid and lateral pterygoid muscles. The temporalis muscle is situated in the temporal fossa, the masseter muscle in the cheek area, while the medial and lateral pterygoids lie in the infratemporal fossa.

Which muscles assists with mastication?

masseter: The large muscle which raises the lower jaw, and assists in mastication.

Which muscles help in chewing food?

Muscles involved in mastication include the masseter, temporalis, medial pterygoid, and lateral pterygoid.

What structures are involved in mastication?

Bones involved in mastication are the maxilla (upper jaw) and mandible (lower jaw). The palate delimits the lower part of the maxilla. The gap between the palate and the mandible defines the oral cavity. The mandible and maxilla are joined together via the temporomandibular articulation (see Fig.

Which are Infrahyoid muscles?

The infrahyoid muscles are a group of four paired muscles that lie inferiorly to the hyoid bone in the anterior aspect of neck. This group of muscles is also known as strap muscles. They connect hyoid, sternum, clavicle and scapula. Infrahyoid muscles are organised in two layers.

What two muscles can work synergistically to perform flexion of the neck?

Name two muscles that can work synergistically to perform flexion of the neck. to the d. Splenius capitis and trapezius are sternocleidomastoid.

What are masseter muscles?

The masseter is one of the muscles of mastication. It is a powerful superficial quadrangular muscle originating from the zygomatic arch and inserts along the angle and lateral surface of the mandibular ramus. The masseter is primarily responsible for the elevation of the mandible and some protraction of the mandible.

Is mastication a chew?

chewing, also called mastication, up-and-down and side-to-side movements of the lower jaw that assist in reducing particles of solid food, making them more easily swallowed; teeth usually act as the grinding and biting surface.

Which of the above helps in chewing?

During chewing, salivary glands in the walls and floor of the mouth secrete saliva (spit), which moistens the food and helps break it down even more. Saliva makes it easier to chew and swallow foods (especially dry foods), and contains enzymes that help begin the digestion of foods.

How many muscles are around the mouth?

Six muscles come together at the modiolus: (1) the zygomaticus major, (2) the orbicularis oris (both the superior and inferior muscles), (3) the levator anguli oris, (4) the risorius, (5) the buccinator and (6) the depressor anguli oris.

What is mastication name two muscles of mastication and their function?

Mandibular division of the trigeminal nerve. There are four classical muscles of mastication. During mastication, three muscles of mastication (musculi masticatorii) are responsible for adduction of the jaw, and one (the lateral pterygoid) helps to abduct it. All four move the jaw laterally.

How does mastication process helps in increasing the surface area?

Chewing breaks the large into the small. The mechanical digestion of food in the mouth involves converting bite-sized pieces of food into smaller particles. This has the effect of increasing the surface area of the food particles and allowing saliva to be thoroughly mixed with them.

Which is the strongest muscle of mastication?

The masseter muscle is the most powerful muscle of mastication. It is quadrangular in shape and has two parts: deep and superficial. The entirety of the muscle lies superficially to the pterygoids and temporalis, covering them.

What are the four muscles of the quadriceps femoris muscle group?

quadriceps femoris muscle, large fleshy muscle group covering the front and sides of the thigh. It has four parts: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.

What are the tongue muscles?

The four extrinsic muscles originate from bone and extend to the tongue. They are the genioglossus, the hyoglossus (often including the chondroglossus) the styloglossus, and the palatoglossus.
