BioSci 107 Lecture 3 - Connective Tissues

These flashcards cover key vocabulary terms and definitions about connective tissues, their components, and functions, as presented in the lecture notes.

Connective Tissue (CT)

Tissue that binds, supports, and strengthens other body tissues, also a major transport system in the body.

Extracellular Matrix (ECM)

Composed of ground substance (GS) and protein fibres; it largely dictates the qualities of connective tissues.

Ground Substance (GS)

A component of the extracellular matrix made up of water, proteins, and polysaccharides.

Glycosaminoglycans (GAGS)

Long unbranched polysaccharides that play a crucial role in the structure of ground substance.

Collagen Fibres

Thick, strong fibres that provide tensile strength and are most abundant in the body.

Adipocytes

Fat cells that store energy in the form of triglycerides.

Fibroblasts

Cells widely distributed in connective tissues that secrete the components of the matrix.

Hyaluronic Acid

A non-sulphated GAG that helps bind cells together and maintains water retention.

Elastic Fibres

Fibres that provide stretch and recoil, found in structures like skin and blood vessels.

Marfan Syndrome

A hereditary condition affecting elastic fibers, resulting in various physical features and vascular complications.

Macrophages

Phagocytic cells in connective tissues that destroy bacteria and cell debris.

Osteoblasts

Bone-forming cells that lay down collagen and initiate the mineralization process.

Reticular Fibres

Thin, branching fibres that form networks in various tissues, providing structural support.

Chondroitin Sulfate

A GAG found in cartilage that provides support and elasticity.

Spongy Bone

Porous inner bone tissue that lies underneath compact bone and contains bone marrow.
