Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

INTRODUCTION TO ERGONOMICS As in all sciences‚ the study of ergonomics is believed to have started with human evolution itself. It has been a quest to find a natural fit between humans and their tools. Just like prehistoric men developed tools to fit their needs‚ for hunting‚ eating‚ sitting and sleeping. With time tools were engineered with an understanding of how we us them and to make them better. As time has passed by engineers have developed tools that fit the humans need‚ in return they
