  • tissue
    a group of cells that are similar in structure to carry out a particular task
  • epithelial tissue is a covering/lining tissue
  • examples of epithelial tissue: outer layer of skin, lining of stomach and intestines
  • in epithelial tissue cells are joined very closely together
  • epithelial tissue cells vary from thin and flat to column shaped and cubed
  • epithelial tissue
  • connective tissue: provides support for body and helps hold all the body parts together
  • examples of connective tissue: bone, cartilage, tendons, ligaments
  • in connective tissue cells are not close together and are separated by large amounts of material called matrix
  • connective tissue
  • muscular tissue also called muscle fibres
  • muscles fibres are long, thin and can contract to become shorter
  • skeletal muscle (voluntary) you can feel and control
  • skeletal muscle has striations (striated muscle)
  • smooth muscle (involuntary) you cannot control
  • smooth muscle has no striations (non-striated muscle)
  • examples of skeletal muscle: biceps, quadriceps, triceps
  • examples of smooth muscle: diaphragm, uterus, intestines
  • cardiac muscle makes up most of the heart
  • nervous tissue is made up of specialised nerve cells called neurons
  • neurons have long projection that carry messages from one end of the body to the other
  • nervous tissue is found in brain, spinal cord and nerves
