what is connective tissue

Connective tissue is the most common kind of tissue out of all of the primary kinds of tissue (epithelial, muscular, connective, and nervous). Loose Connective Tissue. Connective tissue is an essential part of a body. Connective tissue has comparatively few cells. Connective tissue is a connecting framework of cells, aqueous ground substance, and fibers. Connective tissue is a fibrous tissue. Connective tissues are specialized tissues, which provide support and hold the body’s tissues together. It is composed of variety of cells, fibre (non-living products of cell) and semi-solid matrix between cells. Location. Types of Connective Tissues. There's the obvious kind, like tendons, which connect muscles to bones; and ligaments, which connect bones to each other. Connective Tissue: Connective tissue is found in adipose, bone, ligaments, tendons, nerves, cartilage and muscles. Tissue that supports and connects other tissues and parts of the body. In connective tissue, cells are few and dispersed — they are not in close contact, as in epithelial tissue. It is found surrounding blood vessels, nerve bundles, muscles, and organs. Tissue arising chiefly from the embryonic mesoderm that is characterized by a highly vascular matrix and includes collagenous, elastic, and reticular fibers, adipose tissue, cartilage, and bone. Connective tissue distributes the force throughout the limb. The main function is binding … Dense connective tissue is found in joint capsules, muscle fascia, and the dermis layer of skin.
