Desmosomes Study guides, Class notes & Summaries

cardiocytes - ANSWER contractile cells of the heart desmosomes - ANSWER attach cardiocytes together. When one cell contracts, the other will not separate. Think of them like glue between the cells. Connected via gap junctions Electrical and chemical coupling The heart muscle acts as a single functional unit If you had designed a heart, in which the heart muscle cells can contract in unison, what would you do? - ANSWER Innervate only a few muscle cells and have them attach to each other...

Feature of Epidermis - correct answer Cellular, avascular Unique cell type and feature of the stratum spinosum - correct answer Langer Hans cells and desmosomes Desmosomes - correct answer Contact areas between cells of the Stratum Spinosum Unique feature of the stratum basale - correct answer Mitotically active - only layer able to migrate Layers of the epidermis (superficial to deep) - correct answer stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, strat...

What do you think would happen if the elastic fibers in tissues were distensible but not elastic? - ANSWER This would cause the tissues to be unable to resume their original shape and size once the stretching forces were removed. Predict what would happen if the tight junctions in blood vessels were not functional. - ANSWER Tight junctions make the spaces between the cells relatively impermeable to water and many solutes. Nonfunctional tight junctions in blood vessels would allow much of the ...

what are the two layers of the pericardial sac correct answer: outer fibrous pericardium anchors the heart to diaphragm visceral pericardium (epicardium) has a serous membrane what is unique about cardiac muscle (myocardial fibers) correct answer: - no nerves are present intercalated discs at the junctions between fibers (they contain desmosomes, connections to prevent muscle cells from separating during contraction, and gap junctions, which permit ions to pass from cell to cell which fac...
