Anatomy floor of mouth Flashcards
what are the four boundaries of the oral cavity
anterior
posterior
roof
floor
what is the palatal mucoperiosteum
is the convergence of the mucosa of the palate with the palatine bone.
Which masticatory muscle is lined internally with buccal mucosa and has a papilla for the opening of the parotid gland. Opposite maxillary second molar
what is being described
buccinator
what is the name of the region: deepest part of area between tongue and teeth
lingual sulcus
what is the name of the deepest part of cheek
Bucccal sulcus
where is the free gingiva located
where is the mucogingival junction located
where is the attached gingiva located
where is the labial frenula located
where is the upper labial alveolar mucosa located
which area of the mouth is there keratanised mucosa
where is the sublingual papillae located
where is the fimbriated folds located
where is the lingual frenulum located
the deep part of the submandibular gland sits where of the mylohyoid
superiorly
how is the mylohyoid attached together
by the midline raphe
if you was to reflect the mylohyoid muscle, what muscle would you find
geniohyoid muscle
the submandibular ducts anatomical postion compared to the lingual nerve is
he submandibular duct sits superiorly to the lingual nerve.
which papillae on the tongue cannot sense taste
filiform papillae
which nerve innervates the filiform papillae of the tongue
detected by CN V3
which branch ofthe facial nerve detects the special sensory of the tongue
chorda tympani
where is the foramen caecum located
the general taste buds located onthe posterior 1/3rd of the tongue is supplied by which nerve
glossopharyngeal
what is the function of the hypoglossal nerve
motor function of the tongue
intrinisc muscles act to do what to the tongue
alter the shape
longitudinal muscles in the tongue are responsible for
making tongue short and thick
what are the four muscles of the tongue
genioglossus
hypoglossus
styloglossus
palatoglossus
where does the genioglossus attach to
attaches to the genio tubercle located on the mandible
what attaches to the hyoglossus
attaches to the hyoid bone
what attaches to the styloglossus
attaches to the styloid
what attaches to the palatoglossus
attaches to the palatine aponeurosis (tendons of tensor palatini muscle)
all muscles are supplied by cranial nerve 12 (hypoglosal) except which one
palatoglossus (supplied by cranial nerve 10)
clinical testing of the hypoglossal nerve
patients tongue tip points to the left
what does this indicate
the tongue tips points to the side of the damaged cranial nerve (CN 12)
