chapter 9 exam Flashcards
located above each eye, lined with mucus membrane
frontal sinuses
the holes in the frontal bon above the eyes
supraorbital foramen
magnum foramen
houses the spinal cord (largest foramen
lambdoid suture
joins the parietal bone and the occipital bone
forms floor of MOUTH ; elevates (raises) tongue and depresses (lowers) jaw
mylohyoid
assist in swallowing by raising hyoid bone
stylohyoid
draws tongue and hyoid bone forward
geniohyoid
intrinsic
responsible for shaping the tongue during speech chewing and swallowing
extrinsic
assists in the movement and function of the tongue
depresses and protrudes the tongue. located hyoid bone as well as the inferior portion of the tongue
genioglossus
retracts and pulls down the side of the tongue, located on hyoid bone .
hyoglossus
retracts the tongue, (posterior)
styloglossus
elevates the tongue and pulls it slightly backward. connects to soft palate, superior/posterior
palatoglossus
relating to the tongue
glossus
part of the throat at the back of the mouth , behind the oral cavity
oropharynx
upper part of the throat behind the NOSE
nasopharynx
hallow tube that starts behind the nose and ends at the top of trachea(windpipe)
pharynx
forms posterior pillars of fauces , serves to narrow fauces and helps shut off nasopharynx
palatopharyngeus
nasopharyngeal tonsils ( adenoids)
found in the nasopharynx
palatine tonsils
are located in the oropharynx between the anterior and posterior pillars of fauces
lingual tonsils
located on the back of the tongue
saliva passes from which gland into the mouth through a duct called.. also know as ,stensens duct
parotid duct
releases saliva into the oral cavity through Wharton duc which ends in
submandibular
releases saliva into. oral cavity through which duct also known as Bartholin’s duct
sublingual
which produces the largest amount of saliva
submandibular 60%
salivary stones (sialoliths)
may block duct opening, preventing saliva from flowing into the mouth
supplies blood to the brain and eyes
internal carotid artery
provides the major blood supply to the face and mouth
external carotid artery
lingual artery (supplies the tongue)
the lingual artery supplies blood to the tongue and oral cavity. This portion of the external carotid artery branches out to supply blood to surrounding tissues.
maxillary artery
divided into 3 branches, inferior alveolar, pterygoid, pterygopalatine
(cn v) is the primary source of innervation for the oral cavity and the biggest nerve
trigeminal nerve
supplies branches to the buccal mucous membrane
buccal nerve
supplies the anterior two-thirds of the tongue
lingual nerve
can be anesthetized all teeth up to the midline, subsides into a mylohyoid nerve, mental nerve, incisive nerve, and small dental nerves
inferior alveolar nerve
major sites of lymph nodes include
cervical , axillary,inguinal
xerostomia
dry mouth
what two nerves does trigeminal nerve branch into
maxillary, mandibular
closes and puckers the lips
orbicularis oris
compresses the cheeks against the teeth and retracts the angle of the mouth
buccinator
rasises and wrinkles the skin of the chin and pushes the lower lip up
mentalis
draws the angles of the mouth upward and backward as in laughing
zygomatic major
largest salivary gland
parotid
these 3 muscles do what , masseter, temporalis, and medial pterygoid)
involved in closing the jaw
(v)
trigeminal nerve 5
(vii)
facial nerve 7
(xii)
hypoglossal nerve 12
what does zygomatic major do
elevates corners of the mouth
t/f; sternocleidomastoid muscles are a part of neck muscle group
TRUE
where are palatine tonsils located
oropharynx, between anterior/posterior pillars
t/f; stensens duct opens up to the buccal side of the maxilla
true
t/f; geniohyoid muscle is a muscle of facial expressions
false
digastric, geniohyoid, mylohyoid , stylohyoid are muscles of
the floor of the mouth
difference between medial and laterial pterygoid muscle is
medial closes jaw , lateral opens
trapezius is
muscle of the neck
which salivary gland does the sublingual gland open to
Bartholin’s
t/f; mumps is a viral infection of the parotid gland
true
smallest major salivary gland is
sublingual
t/f; lingual artery suppllies the tongue
true
which nerve is affected in bell palsy
facial (vii) 7
rasises mandible and closes jaw (helps close the jaw)
temporalis
what innervates the maxillary molar teeth
posterior superior alveolar nerve (psa)
what innverates maxillary premolar teeth
middle superior alveolar nerve (msa)
what nerve would the dentist anesthetize to work on mandibular molar and pre molar
inferior alveolar
salivary gland associated with circumvallate lingual papilla is
von ebners
What 3 sections do mandibular branch into
buccal nerve, lingual nerve, inferior alveolar nerve
the two main maxillary branches are
Nasopalatine nerve and greater palatine nerve
