What is Adipose Tissue Adipose tissue is the form of loose connective tissue that stores fat in the body in the form of triglycerides.It forms a thick layer under the skin, around the heart, kidneys, joints, and buttock. When a body region is inflamed, the areolar tissue in the area soaks up the excess fluid as a sponge and the affected area swells and becomes puffy, a condition called edema. When blood supply is cut off, the bone tissue dies and the bone collapses. These fibers and cells are embedded in a semifluid ground substance. Many articles describe, in a cursory way, one or another pathologic condition within the Areolar tissue is the dermis and subcutaneous layers of skin, and in the skin, it performs the function of binding the outer skin layer to muscle layer beneath it. Perifascial areolar tissue is a new material that has a rich vascular plexus and that can survive on an area with scarce circulation while providing new blood circulation to the defect. Ans –. characteristics. Adipose tissue is vascular, meaning that the cells are in contact with blood vessels. We don't care how many ads you see or how many pages you view. The tissue is sufficiently flexible to fix many types of defects, such as a plane or spaces with complex shapes, and does not require microsurgical anastomosis.
