Module 6 Intro

Module 6—The Motor System and Homeostasis

Reflect and Connect

Develop ten of your own review questions about muscles and their solutions. Once you have written your review questions, post them to the discussion board for your fellow Biology 20 students to attempt. Choose five different questions written by someone else from the discussion board, and try to complete them as well. Add your own ten questions and answers, plus the five you attempted from the discussion board, to your course folder as a review.

Reflect on the Big Picture

Athletes spend a huge amount of time fine-tuning their motor systems. The contraction of muscles and the use of energy are vital elements of interest to athletes. Since skeletal muscle is controlled voluntarily, it has become the muscle group that humans are most focused on. People have discovered all of the components of these muscles and have figured out the complex actions that cause muscles to contract and relax.

The use of energy and heat production during muscle use is highly researched. You are moving from learning about cellular mechanics of the muscle system in this lesson to how muscles maintain homeostasis in Lesson 2. Think of how your motor system functions as part of your entire body system.

Going Beyond

Why does “warming up muscles” help prevent you from becoming injured? Perform a web search to see if you can discover the reason for doing stretches and warm-ups before doing physical activity.
