What is the shape of a Simple Sqamous Epithelial Tissue? | Single layer of flattened cells. |
What is the shape of a Simple Cuboidal Epithelial Tissue? | Single layer or cells that are as tall as they are wide. |
What is the shape of a Simple Columnar Epithelial Tissue? | Single layer of tall rectangular cells. |
What is the shape of a Stratified Sqamous Epithelial Tissue? | Multiple layers of flattened disk shaped cells. |
What is the shape of a Stratified Cuboidal Epithelial Tissue? | Consists of two or more layers of cells, the upper most being cuboidal (as tall as they are wide). |
What is the shape of a Stratified Columnar Epithelial Tissue? | Column shaped cells in multipe layers. |
What is the shape of Pseudostratified Epithelial Tissue? | Psuedostratified have cells that contact with the basement membrane, but do not reach the apical surface. |
What is the shape of Transitional Epithelial Tissue? | Transitional varies between squamous and cuboidal cells, but always has a dome shape at top of apical. |
What is the function of the Simple Squamous Epithelial Tissue? | Diffusion, osmosis, and filteration. |
What is the function of the Simple Cuboidal Epithelial Tissue? | Absorption and secretion. |
What is the function of Simple Columnar Epithelial Tissue? | Secretion and absorption. |
What is the function of the Stratified Squamous Epithelial Tissue? | Protection against wear-and-tear. |
What is the function of the Stratified Cuboidal Epithelial Tissue? | Protection. |
What is the function of the Stratified Columnar Epithelial Tissue? | Secretion and protection. |
What is the function of the Pseduostratified Epithelial Tissue? | Secretion from goblet cells, movement of mucous across surface by ciliary action. |
What is the function of the Transitional Epithelial Tissue? | Allows destination of organ without causing an increase tension in wall of organ. |
Where is Simple Squamous located? | Lining of heart and blood vessles, lymphatic vessles, alveoli of lungs, glomerular capsule of kidneys, part of serous membrane. |
Where is Simple Cuboidal located? | Lines kidney tubules and small ducts of many glands, covers ovary, for pigmented epithelium of retina. |
Where is Simple Columnar located? | Lines GI tract of stomach to anal canal, ducts of some glands, and gallbladder. Ciliated forms lines oviducts, uterus, and central canal of spinal cord. |
Where is Stratified Squamous located? | Keratinized: SkinNon-keratinized: Mouth, toungem esophagus, anus, and vagina. |
Where is Stratified Cuboidal located? | Lines larger ducts of some glands and part of male urethra. |
Where is Stratified Columnar located? | the ocular conjunctiva of the eye, in parts of the pharynx and anus, the female's uterus, the male urethra. |
Where is Pseudostratified located? | Lines much of the lowers respiratory system, down to bronchiolar level. Nonciliated form may be found in some gland ducts, epididymis, and part of male urethra. |
Where is Transitional located? | Urenary bladder, portions of the ureters and urethra. |
