Chapter 10, Problem 1CSL
Summary Introduction
To explain:
The reason that body becomes stiff after death.
Concept introduction:
Rigor mortis is the third stage of the death that is caused by chemical changes in the muscle resulting in stiffening of the body. In humans, rigor mortis occurs after 4 hours of death.

Your anatomy and physiology course is required for a career in forensics, and one of the short essays is an explanation of why the body becomes stiff after death. Provide an answer for an individual who has some understanding of skeletal muscle physiology.
Muscle physiology: You are in the gym and doing strength training. You feel in good shape and should try to break personal records in squats. You place the bar on your back and start to take in, ie. your motor neurons begin to send action potentials through all your motor units to the thigh muscles. Task 1: Describe how these action potentials lead to your muscles contracting. The description must follow the correct sequence order and you must explain what happens and why. Task 2: What is the contraction called when you a) bend down and b) are in good shape and can generate more force than what the bar weighs c) stay standing in a and the same position without being able to push yourself up while standing?
An isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.
