Lab 7: Bone, Muscle, and Joints Lab
Learning Objectives:
1. Describe the structure of a joint and muscle tissue.
2. Explain the following concepts of muscle physiology: length tension
relationship, fatigue and the action of extension and flexion.
3. Describe and give examples of each of the six types of synovial joints.
4. Describe examples of muscles involved in movements at the joints.
Activity 1. Muscle Fatigue
1. This activity will test muscle fatigue. Stand on the balls of your feet and raise
your heels up off the ground rapidly and powerfully, as you count the number of
times you can do this in 20 seconds. Repeat this activity 10 times without taking a
break. Record your data in the following chart. Before you do this experiment,
make a hypothesis based on what you expect to happen.

1. Hypothesis:
As I move forward with each row, the number of lifts I will be able to do will
decrease as my heel muscles will become fatigued

2. Graph your data below. Label the y axis with the number of lifts. Copy and
paste this graph on a word document so you can print it out, do the graph,
and take a picture of it to submit it as part of your lab submission.
