Oral mucosa consists of two layers, ... Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for ...
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [ 4 ] [ 5 ] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible.
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue .
The mucosa is the innermost layer of the gastrointestinal tract. It surrounds the lumen of the tract and comes into direct contact with digested food ( chyme ). The mucosa itself is made up of three layers: [ 1 ] the epithelium , where most digestive, absorptive and secretory processes occur; the lamina propria , a layer of connective tissue ...
The foliate papillae appear as a series of red colored, leaf–like ridges of mucosa. [2] They are covered with epithelium, lack keratin and so are softer, and bear many taste buds. [2] They are usually bilaterally symmetrical. Sometimes they appear small and inconspicuous, and at other times they are prominent.
Mucoperiosteum is a compound structure consisting of mucous membrane and underlying periosteum.It includes epithelium and lamina propria, but attaches directly to the periosteum of underlying bone without the usual submucosa.
Tissue engineering of oral mucosa combines cells, materials and engineering to produce a three-dimensional reconstruction of oral mucosa. It is meant to simulate the real anatomical structure and function of oral mucosa. Tissue engineered oral mucosa shows promise for clinical use, such as the replacement of soft tissue defects in the oral ...
