Illustrated Epithelium, CTP, and Integumentary Review

5 Written Questions

1. 
   Border between epithelium and CTP, thin, noncellular, consists of proteins secreted by epithelial cells, acts as selective filter as well as scaffolding for migrating regenerating epithelium
2. 
   small bands of smooth muscles that connect each side of the hair follicle to the dermal tissue, cause hair to stand on end when frightened or cold
3. 
   Generally 2 layers of cube like cells, protection, largest ducts of sweat, mammary, and salivary glands
4. 
   Fingerlike extensions of plasma membrane of apical epithelial cells, increase surface area, aid in absorbtion, exist on every moist epithelia, but most dense in small intestine and kidney
5. 
   Unicellular gland produces mucin, precusor to mucus, which protects, covers, and lubricates many internal body surfaces

5 Matching Questions

1. Stratum Spinosum
2. Reticular connective tissue
3. Reticular layer
4. Junctions
5. Mesothemlium

1. a
   80% of thickness of dermis, dense irregular connective tissue,
2. b
   several cell layers thick, spiny appearance to cells from artifacts from desmosomes, cells contain tonofilaments-tension filaments. Langerhans cells found here police outer body surface.
3. c
   Network of reticular fibers in loose ground substance, reticular cells lie in network, forms a soft skeleton to support other cell types like WBCs, macrophages, and mast cells, found in lymphoid organs and spleen
4. d
   Tight Junction- Belt like junction at apical region of epithelial tissues that holds adjacent cells closely to eachother, closing off extracellular space, Adherens Junction-just below the tight junction, reinforces tight junction particularly when tissue is strectched, Desmosomes- join together with neighboring cell's linker proteins as well as intermediate fillaments to form a continuous network of "guy-wires" , desmosomes are most plentiful in tissue that experiences great mechanical stress
5. e
   Simple Squamous Epithelium(Serous membranes) lining pleural, peritoneal, and pericardial cavities

   3. Transitional epithelium
   4. Simple cuboidal
3. Many thick, dead flattened cell layers, dead cells filled with keratin,protect against abrasions and penetration.
   1. Stratum Corneum
   2. Stratum Basale
   3. Stratum Granulosum
   4. Stratum Spinosum
4. 
   Connective tissue proper-realatively few cells, lots of extracellular matrix composed of ground substance(most -soft, gel like substance that holds tissue fluid, In bone it's hard and holds calcium salts) and fibers. Fibrous portion is collagen, reticular, and elastic fibers. 2 types-loose(areolar, adipose, reticular, and dense (irregular, regular, and elastic)
   1. Cilia
   2. Dermis
   3. CTP
   4. Junctions
5. 
   Combination cuboidal and columnar, stretch readily and permit distenstion by urine, found in ureters, bladder, and part of urethra
   1. Endothemlium
   2. Transitional epithelium
   3. Stratum Spinosum
   4. Simple squamos epithelium

5 True/False Questions

   Glands that release proteins (hormones) directly into blood stream

   True        False

2. Stratified squamous →
   Superficial cells elongated and columnar, cuboidal basal cells, protection and secretion, small amounts in male urethra, some ducts and glands

   True        False

3. Stratified Columnar →
   Superficial cells elongated and columnar, cuboidal basal cells, protection and secretion, small amounts in male urethra, some ducts and glands

   True        False

4. Papilary layer →
