Tissues- MGCCC Exam Questions
With Reviewed 100% Correct
Detailed Answers Guaranteed Pass!
Simple Epithelium - ANSWER✔✔-Specialized for absorption or filtration and located
in a region of the body with little wear and tear. Arranged in a single layer.
Stratified Epithelium - ANSWER✔✔-Not specialized for absorption or filtration and
located in an area with a high degree of wear and tear, stacked in several layers.
Psuedostratified - ANSWER✔✔-Less common, has only 1 layer of cells, but some cells
fail to reach the surface, which gives the tissues a multi-layered appearance. Also, the
nuclei in each cell are not at the same level in the cell contributing to a multi layered
effect.
Simple Squamous - ANSWER✔✔-A single layer of flat, scale-like cells resembling a
tiled floor. These cells are found where diffusion and osmosis occur to a high degree.
Lungs, kidneys, heart, line the heart, blood and lymph vessels, form walls of capillaries
(endothelium), forms epithelial layer of serous membranes (mesothelium).
, Simple Cuboidal - ANSWER✔✔-Cube shaped, functions in secretion and absorption,
found in lining the surface of ovaries, lens of the eye, retina, kidneys, gland ducts.
Simple Columnar - ANSWER✔✔-Rectangular shaped, lines the digestive tract,
gallbladder, gland ducts, lungs, uterus and spinal cord. Goblet cells secrete mucous:
lubricated, carries foreign particles. Cilia found in upper respiratory tract, eliminated
foreign particles from lungs.
Stratified Squamous - ANSWER✔✔-Friction, hands and feet. Near surface of skin, flat
appearance. Deeper skin layers cary in shape, cuboidal to columnar. Basal cells move to
surface of skin, cut off from blood supply and die/rubbed off surface. Nonkeratinized-
found on wet surfaces, wear and tear (lining of mouth, tongue, esophagus, vagina).
Keratinized- contain keratin, water proof protein resistant to friction, tough layer.
Stratified Columnar - ANSWER✔✔-Also rare, functions in protection and absorption
(milk ducts in mammary glands.
Glandular Epithelium - ANSWER✔✔-Composed of glands that secrete various
products into the body. Secrete into ducts, surfaces of blood.
Exocrine Glands - ANSWER✔✔-Secrete their products into ducts or a free surface
(mucous, sweat, oil, wax, digestive enzymes) sweat glands, salivary glands, goblet cells.
Holocrine- sebum dies.
Merocrine- cell does not die (salivary gland)
