Other functions are to provide strength, elasticity, support to the parts where this tissue is present. ). Simple theme. It has a branched and mesh-like pattern, often called reticulum, due to the arrangement of reticular fibers (reticulin). Areolar Connective Tissue Definition Areolar connective tissue is a loosely arranged.

Adipose Tissue (fat) Tightly packed & highly vascularized An oil droplet pushes the nucleus to one side. blood cells and mast cells are present, Fibers Areolar connective tissue: These are simplest and most widely distributed connective tissues. The fibrils are not oriented in orderly bundles, as are collagenous fibres; hence they show slightly different chemical responses. Reticular fibers-form framework to help stabilize and support organs. Describe reticular fibers. 21. is richly vascularized but not as much as brown fat. Connective tissue Widely dispersed group of tissues performing variety of functions. collagen fibers but are thinner.

Occur in pads in the palm and sole. Present One important area is the skin (areolar tissue is found in both the dermis and sub-cutaneous layers of the skin - see diagram).The areolar tissue located in the skin binds the outer layers of the skin to the muscles beneath. Areolar Connective Tissue. The left drawing shows a section through a reticular cell, revealing the ultrastructure. Provide Pre Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen (reticulum = net or network).
