histology Flashcards
a group of similar cells that usually have similar embryological origin
tissue
embryological origin of tissue
pluripotent stem cells
points of contact between adjacent plasma membranes
cell junctions
what can tissue be anchored to
other cells, basement membranes, connective tissues
wandering cells
phagocytes/immune cells, embryonic differentiation/growth cells
junction; watertight seal between cells. PMs fused w/ protein strips, common in GI and bladde
tight junctions
junction; binds epithelial cells, made of plaque (dense layer of proteins inside PM)
adherens junctions
junction; channel connection between PMs of 2 cells
gap junctions
junction; cellular rivet, cytoskeletal
desmosomes
half desmosome; connects only to extracellular material (basement membrane)
hemidesmosome
epithelial tissue basement layer
lamina propria (anchored via hemidesmosomes)
what is below the BM (lamina propria)
connective tissue
