what is the structure of connective tissues? (3)
- ground substance (matrix)
- connective tissue cells in ECM (fixed cells for local maintenance/tissue repair/energy storage, blasts, clasts, cytes, and mobile cells for defense)
- matrix fibers (collagen and elastin)
what are some cells you expect to see in connective tissue
- red blood cells
- white blood cells
- macrophages
- adipocytes
- fibroblasts
what are some types of ground substance
- mineralized (bone)
- gelatinous or syrupy (loose or dense connective tissue, cartilage, or adipose tissue)
- watery (blood plasma)
there are 2 protein fibers in the matrix. _____ is for stretch and recoil and ____ is stiff but flexible
elastin
collagen
_________ provide support for small glands and elastic tissues under skin
loose connective tissues
__________ provides strength or flexibility
dense connective tissues
are tendons and ligaments made of loose or dense connective tissues
dense
________ are cells that secrete matrix proteins, ______ is the matrix of loose connective tissues
fibroblasts
ground substance
collagen fibers of tendons are densely packed into ________. tendons connect muscle to bone and ligaments attach bone to bone
parallel bundles
blood consists of ___________ (plasma) plus red and white blood cells and the cell fragments called platelets
liquid matrix
in white fat, the cell cytoplasm is almost entirely filled with ___________-
lipid droplets

type 4
what happens to elastin and hyaluronic acid as you age?
you lose it. your skin becomes less stretchy/stiff and more dry as you age
