Labial Muscles
The extrinsic muscles of the lips are
What are the buccinator, risourius, levator labii superiors, levator labii superiors alaeque nasi, zygomatic major, zygomatic minor, depressor labii inferiors, mentalis, levator anguli oris, depressor anguli oris, Incisivus labii superioris, and Incisivus labii inferioris
The zygomatic major is responsible for
What is pulling backward on the corner of the mouth and lifts it upward and toward the side
The superior longitudinal muscle
What is retracts and broadens tongue, elevates apex of tongue
The genioglossus muscle is responsible for
What is depresses and protrudes tongue (bilateral contraction); deviates tongue contralaterally (unilateral contraction)
The palatoglossus is responsible for
What is depresses the soft palate
The orbicularis oris is responsible for
What is move the lips toward each other and forward (to closure), move the corners of the mouth in several directions, and force the lips and/or corners of the mouth against the teeth
Which muscle pulls chin tissue upward, forces lower part of lower lip against the alveolar process of the mandible, and curls the lower lip outward
What is the mentalis
What muscle retracts and broadens tongue and lowers apex of tongue
What is the inferior longitudinal
What muscle draws (retracts & raise) tongue up & back, pulls sides of tongue up to form trough
What is the styloglossus
Which muscle produces tension of the velum during swallowing
What is palatopharyngeus
What muscle is responsible for pulling the mouth corner backward and toward the side as well as force the lip and cheek against the teeth
What is the buccinator
The depressor labii inferioris is responsible for
What is pullling the lower lip downward and toward the side as well as cause the lower lip to turn outward
The transverse muscle
What is narrows & elongates the tongue
The hyoglossus is responsible for
What is depresses and retracts the tongue or elevates the hyoid bone
The Pharyngopalatine is responsible for
What is pulling downward and backward on the velum
The risorius muscle is responsible for
What is drawing the corner of the mouth backward and toward the side
This muscle draws the corner of the mouth upward and toward the side and may raise the lower lip against the upper lip
What is the levator anguli oris
What muscle broadens and elongates tongue
What is the vertical muscle
The ______ muscle raises the dorsum and root of tongue or lowers the soft palate
What is the Glossopalatis (palatoglossus)
The tensor veli palatini
What is produces tension in the soft palate during swallowing
The Levator labii superioris is responsible for
What is elevating the upper lip
The zygomatic minor is responsible for
What is elevating the upper lip and pulling the corner of the mouth upward
The intrinsic muscles of the tongue are innervated by
What is the XII (hypoglossal) cranial nerve
The function of the extrinsic muscles of the tongue is to
What is altering the position of the tongue.
What muscles draws the velum upward and backward and elevates the soft palate to make contact with the posterior pharyngeal wall (closes off the port)
What is the levator veli palatini
