…The word gets out and anatomy and physiology has become even more popular due to this learning system! It is a very hard, college level class, but the students do fantastic, in part due to the hands-on learning that takes place. …I can’t rave enough about them. I love them from the “births” to their “autopsies” that take place each year.

Mini Lesson #2: Learn Muscle Rules – Muscles Work in Antagonist Pairs

Here is Mini Lesson #2:

1.) Antagonistic muscle pairs are necessary because muscles can only do work by contracting or pulling, and cannot push themselves back into their original positions. Antagonist describes a muscle that acts in opposition to the specific movement generated by the agonist and works to return a limb to its initial position.

Antagonistic muscle pairs are located on opposite sides of a joint or bone. An example of this kind of muscle pairing is the biceps brachii and triceps brachii. When the biceps contracts, the triceps relaxes and stretches back to its original position; the opposite occurs when the triceps contracts.

2.) Reference the ANATOMY IN CLAY® MYOLOGIK® Atlas or Teacher’s Guide for instructions for building biceps brachii and triceps brachii using clay.
