Anatomy Of Oral Region And Pharynx

Oral mucosa consists of two distinct layers.

Anatomy of oral mucosa. The borders of the oral cavity are the lips anteriorly. Oral vestibule lies between the gums and the teeth. Mylohyoid muscle alveolar mandibular ridge and teeth inferiorly.

Abstract the oral route of drug delivery remains the preferred method for the administration of medicinal compounds to humans due to convenience cost and ease of drug administration which not unexpectedly leads to an increase in patient compliance. The oral cavity spans between the oral fissure anteriorly the opening between the lips and the oropharyngeal isthmus posteriorly the opening of the oropharynx. It is bounded by a roof a floor and lateral walls.

The oral cavity is situated anteriorly on the face under the nasal cavities. And the hard palate and maxillary alveolar ridge and teeth superiorly. Circumvallate papillae tonsillar pillars and soft palate posteriorly.

Which type of oral mucosa is softer texture moist easily stretched and compressed lining mucosa what is present in in lamina propria of the lining mucosa that provides the tissue with a movable base. It occurs on the lips soft palate back of the mouth floor of the mouth ventral surface of tongue top of the tongue and alveolar mucosa near the gums and essentially differs in the process of keratinisation because. These three layers are analogous to the epidermal dermal and hypodermal layers of the skin.

Superiorly by the mucolabial and mucobuccal folds and 4. Keratohyalin granules are not formed and thus the granular layer is not. In this review we described the recent development of buccal dosage forms anatomy of buccal mucosa drug transport mechanisms and formulation strategies to enhance the drug permeation through.

The two divisions of the oral cavity are the vestibule and the mouth cavity proper. Lining mucosa nonkeratinized stratified squamous epithelium found almost everywhere else in. It is divided into two parts by the upper and lower dental arches formed by the teeth and their bony scaffolding.

Oral cavity proper lies behind and within the arch of teeth. In many places the oral mucosa is attached to underlying structures by a loose connective tissue component the submucosa fig. Anatomy of oral cavity 1.

Anatomy and physiology of the oral mucosa. Masticatory mucosa keratinized stratified squamous epithelium found on the dorsum of the tongue. Laterally by the cheeks 3.

The surface epithelium is supported by a fibrous connective tissue layer the lamina propria. Oral mucosa can be divided into three main categories based on function and histology. Anteriorly by the lips 2.

Anteriorly it opens to the face through the oral fissure while posteriorly the oral cavity communicates with the oropharynx through a narrow passage called the oropharyngeal isthmus also termed the isthmus of the fauces. It is bounded by a roof a floor and lateral walls.
