locations within the body (Amsel, 2012). The two types of epithelial tissue are (1) covering and lining epithelium and (2) glandular epithelium. The covering and lining epithelium are found lining the integumentary, digestive, cardiovascular, and respiratory systems as well as the ventral body cavity and the organs this cavity houses (Hoehn, et al., 2007, p. 118). The glandular epithelium is found within the glands of the entire human body. Not only are their two types of epithelial tissue found
Tongue (100x: H&E)- Foliate papillae are located on the sides towards the back of the tongue. These papillae are parallel ridges that are lined with stratified squamous epithelium, and separated by mucosal clefts. Within each cleft sit taste buds that are oval in shape and extend through the epithelium. Underneath the epithelium is a layer of loose connective tissue. Lingual serous glands are present in the connective tissue beneath the papillae, and secrete a fluid that is composed of proteins
into the blood stream. Exocrine glands have ducts. Unicellular is one cell (like goblet cells) and is exocrine. Multicellular has many cells and is exocrine also (like sweat glands or salivary glands). The structural types of glandular epithelium are either simple (one duct) or compound (more than one duct). There are three types of glandular secretion: merocrine, apocrine, and holocrine. Merocrine has a fluid product which secretes through the membrane of the cell. It is found in the pancreas
or just a single layer known as simple epithelia. Types of epithelia tissue include the simple epithelia and the compound epithelia: Simple epithelia: Epithelia tissue can have cell shapes these are the Columnar, Cuboidal, and Squamous Cell Shapes. All this cells shapes are part of a type of an epithelia tissue which is the simple Epithelia. There are columnar cells, which means column-like cells and squamous cells, which are flattened and scale-like cells, simple squamous epithelia is found in
that makes up 30% of the semen into urethra contributing to sperm motility and viability. The prostate is classified as a tubulo- alvelolar gland having two distinctive units the epithelium and stroma. The constituents of the stroma are fibroblast , Smooth muscle cells and collagen. The epithelium is mainly simple columnar secretor. In the stromal compartment there are sparse neuroendocine cells (45). The prostate epithelial cells are either classified as basal or luminal. the basal cells are characterized
small intestines and the stomach during the fasting state. Segmentation is described as the contraction that is rhythmic in the small intestines which allows chyme to mix. 15. (NOT APPLICABLE) 16. The mucosa in the colon is composed of simple columnar epithelium and unlike the mucosa of the small intestine it contains no villi or plicae circularis . Although, it does contain crypts. 17. Haustral contractions occur by intervals of 30 minutes, they mix contents inside the intestine back and forth
