PPT 8 Articulation Anatomy Cavities and Muscles Flashcards
the region above the upper lip where a lot of the cranial nerves pass through
philtrum
the part of the upper lip that allows us to have multiple resonance when we talk
cupids bow
what muscle allows you to protrude your lips to blow out air or phonate /u/
orbicularis oris
what muscle is the dominant in the cheek
buccinator
the buccinator muscle assists in
smiling and mastication
superficial to the buccination and assists in mastication and smiling
risorius
what are the functions of the levator labii superior nasi muscle
dilating the nasal cavity to open up, elevating the upper lip
what is the function of the levator labii superior
elevate the upper lip
t/f the labii levatores originate at the same place on the upper
false, they all originate at different sections of the upper lip
also called the muscle for sadness
zygomatic minor
when you frown this muscle helps the upper lip to elevate and move down in an arch
zygomatic minor
also called the smiling muscle
zygomaticus major
works to depress the lower lip
labii depressors
list the three labii depressors
mentalis, trianglars, platysma
All of the muscles of the face are innervated by what cranial nerve
CN VII (facial nerve)
t/f the cranial nerve CN VII is sensory and motor
true, it tells the muscles of the face what to do but it also allows us to feel sensation within these muscles
what are the two portions of the tongue
oral and pharyngeal portions
what structures are parts of the oral portion of the tongue
dorsum, tip, blade, inferior surface, and the root
the lingual tonsils are part of which portion of the tongue
pharyngeal
_ divides the posterior part of the tongue
foramen cecum
_ divides the anterior part of the tongue
central sulcus
what kind of tissue is found in the lingual tonsils
lymphoid tissues
another name for your tongue tie is
lingual frenulum
the _ is located under the tongue near the lingual frenulum
sublingual silivarly gland
what nerve innervates the intrinsic tongue muscles
CN XII hypoglossal
why are the intrinsic muscles of the tongue located closely together
their main function is to give bulk to the tongue
divides the tongue into the left and right tongue at the muscular level
median fibrous septum
the extrinsic tongue muscle innervated by cranial nerve CN X
Palatogossus
what extrinsic tongue muscles are innervated by CN XII
genioglossus, hyoglossus, styloglossus
what extrinsic tongue muscle allows you to protrude and retract your tongue
genioglossus
what extrinsic tongue muscle pulls the sides of the tongue down
hyoglossus
what extrinsic tongue muscle draws the tongue back and up
styloglossus
what extrinsic tongue muscle elevates the back of the tongue
Palatoglossus
list the muscles of mastication
masseter, temporalis, lateral and medial pterygoid, digastrics, mylohyoid, genohyoid, platysma
another names for chewing
mastication
the main bone needed for mastication is
the mandible
what muscle elevates the mandible (you can feel it when you clench your teeth)
masseter
what muscle elevates the mandible and draws it back if it is protruded
temporalis muscle
t/f the lateral and medial pterygoid can work independently
false
the functions of the lateral and medial pteryoid are
elevate the mandible and draw it back if protruded
what are the muscles that allow you to depress your manidble
anterior and posterior belly of digastrics, mylohyoid, and geniohyoid
there is no tendons in your oral cavity instead there is the
aponeurosis
this connects all the muscles in your oral cavity to the muscles around it (the hard palate in this scenario)
aponeurosis
flat sheet that serves as a point of attachment for lots of the muscles in your soft palate
aponeurosis
what velar elevator elevates and retracts posterior velum
levator veli palatini
what velar elevator shortens the velum to bunch it up
musculus uvulae
what is the name of the Eustachian tube dilator
tensor veli palatini
what are the two velar depressors
palatoglossus and palatopharyngeus
aka the anterior faucial pillar
palatoglossus
aka the posterior faucial pillar and narrows the pharynx
palatopharyngeus
aka the oropharynx
superior pharyngeal constrictor
aka the laryngopharynx
middle pharyngeal constrictor and inferior pharyngeal constrictor
expands and elevates pharynx
stylopharyngess
intermingles with superior constrictor mms , expands and elevates pharynx
salpingopharyngeus
together the sylopharngeus and salpingopharyngeus
increase areas of resonance
