connective tissue

• connective tissue functions


  binds body tissues together, supports the body, provides protection
• components of connective tissue

  cells and extracellular matrix (ground substance and fibres)
• connective tissue cells


  fibroblasts, adipocyte, leukocytes and macrophage
• What are fibroblast cell functions?

  produces all fibres of connective tissue, and AGS and secrete collogen proteins
• What are adipocytes cells functions?

  store fat, insulation, protection, and shock absorption
• what connective tissue cell produces connective tissue fibres?

  fibroblast
• what connective tissue cell stores fat

  adipocytes
• What are leukocytes cells?

  white blood cells
• What is a lymphocyte cell?


  immune reactions
• What is a neutrophil cell?

  acute inflammation
• what is a macrophage cells function?

  defence via phagocytosis
• what are in the extracellular matrix?

  collagen, reticulin, elastin
• what is a collagen fibre?

  provides strength to the tissue
• what is a reticular fibre?

  Provide flexible, net-like framework that supports cellular structure
• what is a elastic fibre?

  Provide flexibility and elasticity, Allow for coil and recoil
• What is amorphous ground substance?

  a gelatinous materialthat contains the fibers.
• what are the functions of amorphous ground substances?

  regulates intercellular communication and transports substances
• what makes amorphous ground substance?

  fibroblasts
• What is connective tissue proper?

  loose connective tissue and dense connective tissue
• What types of tissue make up loose connective tissue?

  areolar, adipose, reticular
• what is loose connective tissue composed of?

  mostly amorphous ground substance and little extracellular matrix
• what is the function of loose connective tissue?

  nourishment of the epithelia, immune defence, binding of organs, passageway for nerves and blood vessels
• Where is loose connective tissue located?

  underlining of all epithelia, outer covering of blood vessels and nerves, fascia between muscles and in the pleural and pericardial sacs
• What is dense connective tissue?

  made primarily of elastin or collagen fibbers; forms tendons that connect muscles to bones
• what are dense connective tissue composted of?

  mostly fibres, little cells and amorphous ground substance
• what are the types of dense connective tissue?

  dense regular and dense irregular
• what is dense regular connective tissue?

  Arranged parallel bundles of collagen fibres, and enhances tensile strength and resistance to stretching in the direction of fibres orientation
• what dense connective tissue type attaches bone to bone?

  dense regular
• what dense connective tissue type attaches muscle to bone

  dense regular
• Where is dense regular connective tissue found?

  ligaments and tendons
• what is dense irregular connective tissue?

  dense connective tissue

  irregularly arranged bundles of collagen fibers
• what is the function of dense irregular tissue?

  able to withstand tension exerted in many directions, protects and encapsulates organs
• Where is irregular dense connective tissue found?

  dermis of skin, capsules the liver, spleen and the fibrous sheath around bones
• what are fluid connective tissues?

  blood and lymph
• functions of blood fluid connective tissue

  transports gases, nutrients, hormones, cells and defences against pathogens or microorganisms
• functions of lymph fluid connective tissue

  drainage of excess interstitial fluid from tissue spaces into blood, transports lipids and vitamins and defences cells
• what are supporting connective tissue types?

  cartilage and bone
• what types of cartilage connective tissue are there?

  hyaline, elastic and fibrous cartilage
• what are the functions of cartilage connective tissue?

  Provides support and framework for the body and protects underlying tissue
• Where is cartilage connective tissue found in the body?

  The bones between spine, voice box, ear, nose, surface of bones at joints
