Question
Chapter 45.2, Problem 1CC
Summary Introduction
To determine: The effect on the ability of a muscle to move a bone if its tendon were torn due to injury.
Introduction: The three types of muscle tissue in vertebrates are cardiac muscle, smooth muscle and skeletal muscle. The skeletal muscle is present throughout the body. It is directly involved in locomotion. It can generate action potentials in response to a stimulus. This results in an increased calcium ion concentration in the cytosol, which triggers force generation.

Some of the meat was very white and someof it was much darker. From the color of the meat, Alex guessedwhich muscles the bird used for maintenance of posture and/or slowmovements, such as walking, and which muscles it used for quickermovements, such as running or flying.
