Wild Card
Refers to how the oral cavity creates speech sounds and is dependent on the vocal tract cavities to shape the acoustic output
The source-filter theory
This group of muscles anchor the tongue firmly to surrounding bones and work to reposition the tongue
Extrinsic tongue muscles
This muscle pulls the corners of the mouth laterally
Risorius m.
This group of muscles alter the shape of the tongue for talking and swallowing
Intrinsic tongue muscles
The function of this muscle is to elevate the mandible and assist in the grinding action of the jaw
Masseter
This muscle pulls the hyoid up and forward
Anterior belly of the digastricus
The function of this muscle is to narrow the tongue
Transverse m.
This muscle pulls the angles/corners of the mouth upward and laterally
Zygomatic major m.
This muscle elevates the tongue and depresses the soft palate
Palatoglossus m.
Name the muscle that is responsible for tensing and flattening the soft palate
Tensor veli palatini
T/F: the lateral pterygoid muscle protrudes the mandible (through bilateral contraction), assists in grinding actions, and elevates the mandible.
False. The lateral pterygoid muscle protrudes the mandible (through bilateral contraction), assists in grinding actions, and depresses the mandible.
This muscle draws the tongue up and back
Styloglossus m.
When this muscle contracts it constricts the oropharynx and helps move the bolus onto the grinding surface of the molars
Buccinator m.
This muscle pulls the tongue down into the floor of the mouth
Vertical m.
Name the elevator muscles of the velum
Levator veli palatini, musculus uvulae
This muscle completes the velopharyngeal seal during swallowing
Superior pharyngeal constrictor
The function of this muscle is to pull the tip of the tongue downward, retract, and deviate the tongue
Inferior longitudinal m.
What muscles comprise the anterior and posterior faucial pillars and what do they do?
Palatoglossus= anterior; elevates the tongue or depresses the palate
Palatopharyngeus= posterior; narrows the pharynx and lowers the soft palate
Hyoglossus m.
Name all the muscles that depress the mandible
Lateral pterygoid
Mylohyoid
Geniohyoid
Platysma
T/F: the pharyngeal musculature is a complex group of muscles the, when contracted, constrict the pharynx and assist in mastication.
False. the pharyngeal musculature is a complex group of muscles the, when contracted, constrict the pharynx and assist in swallowing (diglutition).
The function of this muscle is to retract, protrude, and depress the tongue
Genioglossus m.
The combined function is to elevate the upper lip
Levator labii superioris m.
Zygomatic minor m.
Levator labii superioris alaeque nasi m.
This muscle elevates, retracts, or deviates the tongue tip
Superior longitudinal m.
Name all the muscles that elevate the mandible
Masseter
Temporalis
Medial pterygoid
