The Oral Cavity
The Oral Cavity
The Oral Cavity Consists of two parts o Oral vestibule between cheeks and lip and teeth a Oral cavity proper: Within arch of teeth Boundaries o Anterior and lateral: gum and teeth Posterior: isthmus of fauces Roof: palate a Floor: tongue, muscles and mucous membrane Oral vestibule leads, by the space behind the molar teeth into the oral cavity proper
The Oral Cavity ◼ Consists of two parts ❑ Oral vestibule : between cheeks and lip and teeth ❑ Oral cavity proper : within arch of teeth ◼ Boundaries ❑ Anterior and lateral: gum and teeth ❑ Posterior: isthmus of fauces ❑ Roof: palate ❑ Floor: tongue, muscles and mucous membrane ◼ Oral vestibule leads, by the space behind the molar teeth, into the oral cavity proper
Palate Two parts a Hard palate anterior 2/3 formed by the maxilla and palatine bone Soft palate: posterior 1/3 Velum palatinum Uvula Palatoglossal arch Palatopharyngeal arch sthmus of fauces formed by uvula, free border of velum palatinum, both side of palatoglossal arches, and root of tongue
