in the medulla. More specifically, the medullary cords.
Yes, the inside of the mouth is lined with non-keratinized stratified squamous epithelial cells. As in most mucous membranes, that is the main tissue type. Parts of the gums, hard palate, and tongue are slightly keratinized, but not nearly as much as the skin outside the mouth is keratinized.
During development, the embryo contains keratinized cells in a number of places. One unique spot is in the lining of the esophagus, which is normally not keratinized in adults. In adults, keratinized cells form the topmost layer of the skin (the stratum corneum of the epidermis).And the fingernails
Stratified squamus keratinized
medulla oblongata
the keratinized tissue is found in the masticatory mucosa, which includes the hard palate,the gingiva, the dorsum of the tongue and the outer part of the lips.
The upper layer of skin i.e. Epidermis is composed of dead Keratinized epithelium cells.
in the medulla. More specifically, the medullary cords.
Stratified squamous epithelium has many layers of flattened cells and function in protection. There are two types: non-keratinized: found in the lining of the mouth, the throat, the vagina, and the anus. The second type is keratinized and is found as the epidermis of the skin.
Yes, the inside of the mouth is lined with non-keratinized stratified squamous epithelial cells. As in most mucous membranes, that is the main tissue type. Parts of the gums, hard palate, and tongue are slightly keratinized, but not nearly as much as the skin outside the mouth is keratinized.
The stratum cornium has keratinized cells.
This is called the nail matrix.
This is called the nail matrix.
In this case, the most apical layers (exterior) of cells are dead and lose their nucleus and cytoplasm, instead contain a tough, resistant protein called keratin. This specialization makes the epithelium waterproof, so is found in the mammalian skin.
Keratosiskaratosis
Pheochromocytomas can be found anywhere chromaffin cells are found. They may be found in the heart and in the area around the bladder, but most (90%) are found in the adrenal glands
Nails are made up of layers/plates of keratinized epithelial cells.
