What are the muscles of the head? - ANSWER: Pharynx, mastication, facial expression, neck, the floor
of the mouth, tongue, and soft palate
Major Muscles of facial expression - ANSWER: Orbicularis oris, buccinator, mentalis, and zygomatic
major
Muscles of the floor of the mouth - ANSWER: Digastric, mylohyoid, stylohyoid, and geniohyoid
Muscles of the Neck - ANSWER: Sternocleidomastoid and Trapezius
Muscles of the Tongue - ANSWER: Intrinsic and Extrinsic
Sternocleidomastoid - ANSWER: Divides neck region into anterior and posterior cervical triangles;
serves as a landmark of neck during extraoral examination
Trapezius - ANSWER: Lifts clavicle and scapula (shoulder blade), as when shoulders are shrugged
Orbicularis oris - ANSWER: Closes and puckers lips; aids in chewing and speaking by pressing lips
against teeth
Buccinator - ANSWER: Compresses cheeks against teeth and retracts angle of mouth
Mentalis - ANSWER: Raises and wrinkles skin of chin and pushes up lower lip
Zygomatic major - ANSWER: Draws angles of mouth upward and backward, as in laughing
Muscles of the Soft Palate - ANSWER: Palatoglossus and palatophyaryngeus
Muscles of Mastication - ANSWER: Temporal, Masseter, internal (medial) pterygoid, and external
(lateral) pterygoid
Temporal - ANSWER: Raises Mandible and closes jaws
Masseter - ANSWER: Lower border of the zygomatic arch; raises Mandible and closes jaw
Internal (medial) pterygoid - ANSWER: Closes jaw
External (lateral) pterygoid - ANSWER: Depresses Mandible to open jaw
Mylohyoid - ANSWER: Forms floor of mouth; elevates tongue and depresses jaw
Digastric - ANSWER: Anterior belly: lower border of Mandible
Posterior belly: mastoid process of temporal bone
Stylohyoid - ANSWER: Assists in swallowing by raising hyoid bone
Geniohyoid - ANSWER: Draws tongue and hyoid bone forward
