The connective tissues of the muscle, from deep to superficial. The endomysium is a sheath of loose connective tissue surrounding each fiber, allowing blood capillaries and nerves to reach it. The perimysium is a thicker connective tissue sheath bundling fibers into fasicles. The epimysium is the fibrous sheath surrounding the entire muscle. The fascia is the most superficial connective tissue; it can be deep (between adjacent muscles) or superficial (between muscles and skin).
Aipose tissue or body fat or just fat is loose connective tissue composed mostly of adipocytes. The two types of adipose tissue are white adipose tissue (WAT) and brown adipose tissue (BAT). The formation of adipose tissue appears to be controlled in part by the adipose gene.
