CAS BI 106 Lecture Notes - Lecture 3: Connective Tissue, Loose Connective Tissue, Collagen
Document Summary
Connective: diverse group of tissues that connect body parts together, 3 basic components, cells, protein fibers (thick/thin collagen, ground substance ( extracellular matrix made up of lipids, proteins, and lots of water) Common features of connective tissue: cells are not in contact with each other, highly vascularized. Types of connective tissue: fibrous connective tissue(several sub types, adipose tissue, supportive connective tissue (several sub types, cartilage and bone, fluid connective tissue (blood) Cells found in connective tissue cells: fibroblasts (fiber-creators, produce the fibers and ground substance that form the matrix of the tissue, scattered adipocytes (fat cells, some resident and some wandering immune cells. Fibers: collagenous fibers, made of the protein collagen (main component of leather and glue, tough, flexible, does not stretch well, very common. Imparts the ability to stretch and recoil back to original shape. Ground substance: anatomical name for extracellular matrix (ecm) around cells in connective tissues.
