Skeletal Muscle Contraction

MATERIALS NEEDED

textbook recording system (kymograph, Physiograph, etc.)

stimulator and connecting wires live frog dissecting tray dissecting instruments probe for pithing heavy thread frog Ringer's solution

For Demonstration A—the Kymograph:

kymograph recording system electronic stimulator (or inductorium) frog muscles (from pithed frog) probe for pithing dissecting instruments frog Ringer's solution

For Demonstration B—the Physiograph:

Physiograph myograph and stand frog muscle (from pithed frog) probe for pithing dissecting instruments frog Ringer's solution

Virtual Physiology Lab: 3, Frog Muscle ing systems and stimulated by electrical shocks of varying strength, duration, and frequency. Recordings obtained from such procedures can be used to study the basic characteristics of skeletal muscle contractions.

Essentials of Human Physiology

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
