adipose tissue description

specialised loose CT has lots of adipocytes, it insulates and functions as padding providing a ready source of fuel for metabolic processes

10%-15% of body weight, highly labile tissue, specialised for synthesis and storage of lipids

has small blood vessels adipocytes occur singly or in clusters that are arranged in lobules surrounded by fibrous septa

lipid droplets

coalesce into a large droplet, leaving a thin rim of cytoplasm and the nucleus is pushed to the side

how to stain adipose

sudan III + H-E

properties of reticular fibres

hydrophilia, metachromasia, optical homogenity

stain for reticular fibers

AgNO3

what is reticular fibres replaced by during wound healing?

type I collagen
