Structure and Function

Composition/Function:

• Cells (9)
• Extracellular Matrix

Connective Proper:

Loose Vs Dense Vs Adipose

• Loose - Much Ground Substance, Many Cells, Less Collagen. Random arrangement.
  • Supports Microvasculature, Nerves, Immune cells
    • Eg. Lamina Propria (Basement Membrane)

• Dense Regular - More Collagen Fibres, Less ground substance, Few Cells. Fibres run Parallel.

  • Withstands pressure/force along one axis and anchors to a structure. Connects musculoskeletal system.
    • Eg Tendon - Binds muscle perimysium, epimysium to periosteum. Confluence of contractile force.

  

• Dense Irregular - More Collagen, Randomly arranged fibres. Little Ground Substance and Cells.

  • Withstands Force from multiple directions, Resists Tearing, Protects & Supports organs.
    • Dermis, Organ Capsules, Submucosa
