sketches.

4. Flex the chicken leg, record your observations.
i. Research to determine the names of this type of muscle movement.
ii. Give an example of this type of muscle on the human body.
5. Extend the chicken leg, record your observations.

functions.

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
