About This Simulation
Muscle is one of the most abundant tissues in animals and humans. It is composed by cells with the ability to contract and therefore provide a particular movement to different parts of the body. This movement can be voluntary or involuntary, depending on which part of the nervous system is controlling it. Hence, there are three main types of muscle tissue: Skeletal, smooth, and cardiac muscle. Smooth muscle is a type of muscle tissue, which cells do not have striations and are controlled by the autonomic nervous system, which is the one responsible for the involuntary control of organs.
In the Smooth Muscle Simulation, you will learn the basics of smooth muscle contraction to help you understand why your digestive process has been long and painful lately. You will perform different experiments using a piece of intestine from a rat, adding different neurotransmitters and drugs to understand how it is controlled by the nervous system. Will you be able to identify the cause of your intestinal discomfort?
