Lab 7:Bone, Muscle, and Joints LabLearning Objectives:1.Describe the structure of a joint and muscle tissue.2.Explain the following concepts of muscle physiology: length tensionrelationship, 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 Fatigue1. This activity will test muscle fatigue. Stand on the balls of your feet and raiseyour heels up off the ground rapidly and powerfully, as you count the number oftimes you can do this in 20 seconds. Repeat this activity 10 times without taking abreak. Record your data in the following chart. Before you do this experiment,make a hypothesis based on what you expect to happen.TrialNumber# of lifts14324033943653463273082792510231.Hypothesis:As I move forward with each row, the number of lifts I will be able to do willdecrease as my heel muscles will become fatigued
