Connective Tissue (CT)

Tissue that binds, supports, and strengthens other body tissues, functions as a major transport system, and serves as a site for energy storage.

Extracellular Matrix (ECM)

The non-cellular component of connective tissue, consisting of ground substance and protein fibers.

Ground Substance (GS)

The gel-like material in the ECM that contains water, proteins, and polysaccharides.

Glycosaminoglycans (GAGs)

Long unbranched polysaccharides that join with core proteins to form proteoglycans.

Proteoglycans

Molecules composed of a core protein and glycosaminoglycans that help trap water in the ground substance.

Collagen Fibers

Thick, strong fibers that provide tensile strength and resistance to pulling forces in connective tissues.

Reticular Fibers

Thin, branching fibers composed of collagen that provide support and form networks in various tissues.

Elastic Fibers

Thin fibers composed of elastin that allow tissues to stretch and return to their original shape.

Adipocytes

Fat cells that store energy in the form of triglycerides and are found below the skin and around organs.

Macrophages

Phagocytic cells that destroy bacteria and cell debris through the process of phagocytosis.

Hyaluronic Acid

A unique glycosaminoglycan that attracts water and contributes to the jelly-like consistency of the ground substance.

Fibroblasts

Cells that secrete components of the extracellular matrix, including fibers and ground substance.

Marfan Syndrome

A hereditary condition caused by a defect in elastic fibers, leading to tall stature and possible cardiovascular issues.

Chondroitin Sulfate

A sulfated glycosaminoglycan found in cartilage, providing support and adhesive features.

Bone Tissue

A type of supporting connective tissue characterized by a solid, crystalline extracellular matrix.

Osteon

The basic structural unit of compact bone, consisting of concentric rings of mineral salts and collagen.

Liquid Connective Tissue

Blood, which consists of plasma and formed elements, including red blood cells, white blood cells, and platelets.

Neutrophils

White blood cells that migrate to sites of infection to destroy microbes through phagocytosis.

Eosinophils

White blood cells involved in combating parasitic infections and allergic responses.

Mast Cells

Cells found alongside blood vessels that produce histamine during inflammatory responses.

Adipose Tissue

A type of loose connective tissue dominated by adipocytes, used for energy storage, insulation, and temperature control.
