Oral cavity

• this lies between the gums and teeth?

  oral vestibule
• this lies behind and within the arch of teeth?

  oral cavity proper
• three vestibules?

  labial vestibule lower, labial vestibule upper, buccal vestibule
• consist of dense vascular fibrous tissue, they are continuous with the mucosa of the oral vestibule externally and the palate or the floor of the mouth internally?

  gums and gingivae
• it forms the superior wall or the roof of the oral cavity proper?

  hard and soft palate
• hard palate is composed of?

  osseous base
• soft palate is composed of?

  fibrous tissue
• hard palate ic covered by?

  mucoperiosteum
• forms a partition between the oral and nasal cavities?

  hard palate
• this is thin in the middle but thicker at the sides due to the presence of numerous glands?

  mucoperiosteum
• the hard palate was formed by?

  palatine process of maxilla, horizontal palate of the palatine bone
• is a longitudinal ridge extending from the uvula to the incisive papilla?

  median raphe
• is a small projection of the mucosa indicating the location of the incisive foramen and the anterior limit of the median raphe?

  incisive papilla
• are about six distinct elevation crossing the anterior part of the hard palate?

  transverse palatine process or palatine rugae
• are small inconstant pits on the posterior margin of the hard palate on either side of the median raphe

  fovea palatine
• Is the posterior movable portion of the

  palate, extending from one side of the

  pharynx to the other, and attached to

  the posterior border of the hard palate?

  soft palate
• is the median conical projection marked by median raphe?

  uvula
• are free margins of the soft palate and splitting into two parts as they approach the lateral wall

  palatine arches
• anterior pillar of fauces or anterior palatine arch encloses the palatoglossus muscle?

  palatoglossal arch
• posterior pillar of fauces or posterior palatine arch encloses the palatopharyngeus muscle?

  palatopharyngeal arch
• mobile mass of muscles lying on

  the floor of the mouth and associated

  with the function of taste, chewing,

  swallowing, and speaking?

  tongue
• is visible when the mouth is opened, covered by papillae?

  palatine part
• is a faint groove separating the palatine part into symmetrical parts?

  median sulcus
• is a small pit at the apex of the

  sulcus terminalis?

  foramen caecum
• is the posterior 2/3s of the

  tongue which contains

  serous glands and nodules of lymphoid

  tissue – LINGUAL FOLLICLES

  Pharyngeal part
• is the reflection of the mucous membrane of the

  tongue on to the epiglottis

  producing elevation?

  glosso-epiglottic fold
• are the largest, numbering from 7-12, and are

  arranged in front of the sulcus terminalis?

  vallate or circumvallate papillae
• are fewer in number and are limited to the tip and margins of the tongue?

  fungiform papillae
• are the smallest and the most numerous, scattered all over the

  anterior 2/3 of the dorsum of the tongue?

  filiform papillae
• are small sized vertical

  folds located on the tongue’s

  posterolateral sides, just anterior to the

  palatoglossal arch of fauces?

  foliate papillae
• are receptor organs for the special

  sensation of taste?

  taste buds
• responsible for changing position of the tongue?

  extrinsic muscle
• extrinsic muscles?

  G, H, S
• Intrinsic muscles?


  S&I LM, TM, VM
• intrinsic muscle that located close to the dorsum of the tongue

  S&I LM
• intrinsic muscle that Shorten the length of the tongue and to curl the tip of the tongue and back?

  S&I LM
• intrinsic muscle the narrows the tongue?

  transverse muscle
• intrinsic muscle that flattens the tongue?

  vertical muscles
• A large lingual frenulum can limit the

  mobility of the tongue and interfere with

  speech?

  tongue tie
• salivary glands of the oral cavity?

  parotid gland, submandibular gland, sublingual gland
