Tissues

• Tissue - A group of similar cells that work together to carry out a particular function
• Muscular tissue

  • Long and thin
  • Contract to become shorter
  • 3 types of muscular tissue - Skeletal, Smooth and cardiac
• Skeletal muscles

  • Muscles attached to the bone
  • e.g. arms and legs
  • We can move them when necessary

  
• Smooth Muscle

  • Found in the walls of the stomach and intestines
  • We cannot contract smooth muscles voluntarily

  
• Cardiac Muscle

  • Makes up most of the heart
  • The heart muscle cannot be voluntarily contracted

  
• Connective tissue

  • Provides support
  • Helps hold up the whole body
  • Cells are not close togther
  • Separated by large amounts of Matrix (non-cellular)
  • e.g. Bones, cartilage, tendons, ligaments and fat storage
• Epithelial tissue

  • A covering or lining tissue
  • Our skin is epithelial tissue
  • The cells are very close together
• Nervous tissue

  • Made of specialised nerve cells called neurons
  • Used to carry messages from one part of the body to another
