Document Summary

Connective tissue is the most diverse and abundant type of tissue. Collagen fibers strong, tensile strength largest diameter with rope-like structures. Elastic fibers recoil function contains branches that form networks intermediate diameter with long fibers. Reticular fibers support, special collagen fibrils cluster into networks small diameter. Areolar loose connective tissue (proper) gel-like matrix with fibroblasts, macrophages, and some wbcs. Wraps and cushions organs, role in inflammation, holds tissue fluid located under epithelium of body, packages organs and surrounds capillaries. Adipose loose connective tissue (proper) sparse gel-like matrix, closely packed adipocytes that push nucleus to side provides saved food fuel, insulates against heat loss, supports organs located under skin in hypodermis, around kidneys and eyes, within abdomen and breasts. Reticular loose connective tissue (proper) network in loose ground substance containing reticular cells form soft internal skeleton that supports other cell types located in lymphoid organs. Dense regular connective tissue (proper) parallel collagen fibers, fibroblast major cell type attaches muscles-bones, muscles-muscles, bones-bones.
