       2. Examine the skin with/without the stereomicroscope, record your observations via making
       sketches.

               the other one contracts

                 leg                         contracts


       6. Locate and slice the tendons: describe what it looks like, its texture, colour, predict its
      functions.

              - look like noodles                                      muscle and bone
  Tendons     - stretchy                                               (attach muscles
              - hard                                                   with bones)
              - feels like a string                               - help with
              - 9 tendons                                              movement of the

              - shiny                                             - could be the
              - very smooth                                            muscle insertion

                                                                       of muscle

       7. Count the number of muscle groups that are attached to the tendon for your chicken leg.
       There were at least two muscle groups and a total of nine muscles. One is located at the front of
       the leg and the other one at the back of the leg. Both of the groups of muscles resemble the
       tibialis anterior and the gastrocnemius of the human body. The muscle group behind the leg was
       thin and short whereas the one in front was thick and attached to the main muscles.
       8. Locate the biggest blood capillaries, record your observations

                                    The biggest blood capillaries are located on the inside of the skin
                                    and on the middle of the muscles. The blood capillaries are long
                                    and thick, which branch out like twigs. Starts of thin to tick.




       10. Locate and examine the meniscus and ligaments, record your observations via making
       sketches
