lecom histology quiz1 with correct answers 100% 2026 basement membrane- composition? - Correct Answer The basement membrane is a thin, fibrous, extracellular matrix of tissue basement membrane- function? - Correct Answer separates the epithelium (skin, respiratory tract, gastrointestinal tract, etc), mesothelium (pleural cavity, peritoneal cavity, pericardial cavity, etc) and endothelium (blood vessels, lymph vessels, etc) from underlying connective tissue. hemidesmosomes - Correct Answer Attachment plaque Intermediate cytokeratin filaments Integrins family Function: tight adhesion to basal lamina apical - Correct Answer top side closest to lumen or outside... whatever is touching air zonula adherens - Correct Answer made of actin filaments- CAM's (cell adhesion molecules) desmosome (macula adherens) - Correct Answer very thick fibers in the middle connected by intermediate filament- remember cadherin family thus zig zigging molecules like a zipper gap junctions (nexus) - Correct Answer Connexins Generate a central pore Communication (passing information) stratified epithelium - Correct Answer squamous karatanized usually MUCH more layers- rougher -skin, roof of your mouth, non-karatanized- smoother, usually where there is a moist surface - vagina, nose, anus, mouth cuboidal found in ducts (larger ducts), sebatous glands- never really more than two layers columnar found in ducts- pretty rare- elongated nucleus is what tips it off that its columnar glycocalyx - Correct Answer protein secreted near microvili stereocilia - Correct Answer cilia that don't move transitional - Correct Answer transitional (aka urinary epi) looks cuboidal but they are more rounded (balloon/umbrella cells)- its for bladder stretching endocrine gland - Correct Answer secrets into bloodstream mucous cells - Correct Answer secretion is viscous, mucus have tubules so a little pond lake thing and there are little puff things coming off the pond submandibular and sublingual, goblet cells merocrine - Correct Answer No loss of cytoplasm Most common mode salivary glands holocrine - Correct Answer Entire cell lost- sebacius gland (making sebum) compound gland - Correct Answer branched alveolar - Correct Answer hs the little tufts _think about hwo the lungs looks myoepithelial cell - Correct Answer these help push fluid through via contraction as they sit on the cap and pushes it through basal lamina - Correct Answer lamina lucida - Correct Answer anchoring fibrils - Correct Answer polarity - Correct Answer apical surface (associated with the air or the opening), basal surface (its the part that holds to the basement membrane zonula occludens - Correct Answer ike a belt that surrounds the cell fusing the adjacent membrane (most apical thing) tonofilaments - Correct Answer Made up of keratin - loop through desmosomes - junctions between neighboring cells simple epithelium - Correct Answer Squamous generally has a prominent nucleus looks like tiles from the top blood vessels- alveoli cuboidal very round nucleus kidney tubes
