AT (CONNECTIVE TISSUE)

• Connective tissue


  General biology term
• Blood


  Only fluid connective tissue, made up of plasma, erythrocytes (RBC), leukocytes (WBC), and platelets for blood clotting
• Adipose tissue


  Fat tissue, located in the stomach area
• Membranes


  • Cutaneous
  • Mucous
  • Serous
• Membranes


  • Contain glands, open to outside (cutaneous, mucous), occur in paired sheets, don't open to outside (serous)
• Connective tissue


  • Possess fibers, widely scattered cells, ground tissue (matrix), binds together, supports, and strengthens other body tissues, protects and insulates internal organs, compartmentalizes structures such as skeletal muscles, major transport system within the body (blood, a fluid connective tissue), the primary location of stored energy reserves (adipose, or fat, tissue), the main source of immune responses
• Areolar connective tissue


  Loose irregular, made up of collagenous fibers found in tendons and ligaments (holds bones together and keeps them in place)
• Adipose tissues

  • Insulate the body and store energy
• Cartilage


  Dense regular, characterized by collagenous fibers embedded in chondroitin sulfate, functions as cushion between bones at the tips of external ears, bronchi, vertebral column, etc., Chondrocytes are the cells that secrete collagen and chondroitin sulfate
• Ligament

  • Elastic fibers, collagen fibers, fibroblasts, macrophage, mast cell
• Bone


  Mineralized connective tissue made by bone-forming cells called osteoblasts which deposit collagen, forms the framework of the body
