in the oral cavity, whts all of :
oral fissure
orophharyngeal isthmus
oral vistibule
oral cavity proper
- opining between the 2 lips, from oral vestibule to the outside
- The narrow space between the two palatoglossal fold
- space between the lips & cheek externally And the gum & teeth internally
- the main part of the oral cavity
_______ is almost always closed, contains the parotid papilla, divided into ____ sulci and haas the frenulums which are_____
oral vestibule
6 sucli
connecting lips to gums and cheeks too
the roof of oral cavity proper is _____
and the posterior part i ________
anteriorly ________
hard palatine
isthmus
oral vestibule
hard palatine is formed by what bones
and it forms ____ of the palatine
palatine process of the maxilla
horizental plate of the palatine bone
2/3
______ is part of the pharynx. and has all of the following muscles:
palatoglossus, palatopharyngeus, uvulae msuculus, levatorr veli palatine and tensor veli palatine
soft palatine
The vestibule communicates with oral cavity proper at:
a. retromolar space
b. freeway space
order of primary teeth eruption:
lower: order
upper: canine then 2nd molar
order of permanent teeth eruption:
lower: 1st molar then order
upper: 1st molar > order > canine the the 2nd premolar
innervation of the teeth is by ___
trigeminal nerve specially the mandibular and maxillary branches
innervation of upper teeth, buucal annd gingiva,, and palatine
- post. , middle , ant. superior alveolar branches of the maxillary trigeminal nerve
- same as teeth
-nasopalatine and great palatine nerves
innervation of lower teeth, buucal annd gingiva,, and palatine
- inferior alveolar branch which primary innervates the molar and premolar, and its imcisive branch than innervates the rest
- buccal branch of the posterior mandibular and the mental branch of the IAN
- lingual nerve of the post. mandibular
anterior part of the tounge originates from_____ and innervated by ____
and same for post
?????????
- 1st pharyngeal arch and trigeminal
- 3rd pharyngeal arch and the glossopharyngeal
Foramen cecum is:
Blind opening (small depressed pit) at the apex of sulcus terminalis
thyroglossal duct
- Keratinized for protection
- The smallest (microscopic), most numerous (scattered all over the tongue)
- Whitish appearance
- has no taste buds
Filiform (hair like)
- Scattered all over the dorsum & mostly concentrated at the tips & margins
- has taste buds
- Appear as red dots
Fungiform
The largest, 8-12 in number, very conspicuous
Located in front of sulcus terminalis, has a taste bud
Vallate (circumvallate)
Linear folds, located at the sides near terminal sulcus, has a taste buds
Rudimentary & not well developed in human (developed in animals like cat)
Foliate
fimberiated folds are:
finger-like projections just lateral to the deep lingual vein.
muscles that form the root of the tongue:
genioglossus muscle (bulk of tongue)
hyoglossus
intrinsic muscles of the tongue:
Superior & inferior longitudinal muscles: shorten the tongue
Transverse muscles: narrowing the tongue
Vertical muscles: flattens the tongue
extinsic muscles of the tongue
genioglossus: superior genial tubrcle
hyoglossus: greater horn
palatoglossus
styloglossus
innervations of the tongue for general sensation and special sensation and motor
- lingual nerve of the mandibular devision
glossopharyngeal nerve - choroda tympani of the facial nerve
glossopharyngeal nerve - mainly hypoglossal nerve
blood supply of the tongue:
- lingual artery is an anterior branch of the external carotid artery
- tonsilar artery from facial nerve
- ascending pharyngeal artery medial branch of the external carotid artery
branches of the inguinal artery of the tounge
- dorsal lingual branch : posterior third
-deep lingaul branch: body and apex - sublingual branch: floor of the mouth
