extracellular matrix Flashcards
1
Q
what is the extracellular matrix
A
made of mostly collagen fibers interwoven with proteoglycans.
holds cells together to form tissue, allows for communications with other cells
2
Q
proteoglycan
A
carbs and protein
3
Q
intercellular junction
A
cells communicate via direct contact
4
Q
adhesion junction
A
animals. (desmosome) intercellular filaments between cells
5
Q
tight junction
A
animals. form zipper like, impermeable barrier between cells. (skin)
6
Q
gap junction
A
plasma membrane channels are joined
7
Q
plasmodesmata
A
channel between 2 adjacent plant cells walls. Allows materials to pass from one plant’s cytoplasm to another
8
Q
desmosome
A
animals. a well between epithelial cells, maintains the cells in a sheet like formation in organs. (heart, skin, muscles)
