Why you need to know about muscle anatomy

“Muscles” are easily the largest topic to understand for your level 2 Anatomy and Physiology exam.

It is also important for understanding the practical element of training clients and planning. This becomes the foundation of understanding how muscles work in preparation for moving onto Level 3 knowledge about the body in motion.

4 Facts you need to KNOW about Muscles

These 4 facts are crucial to understanding the foundations of muscle anatomy.

1: A Muscle must cross a joint to make it move
2: Muscles work in pairs around a joint – Agonist/ Antagonist pairs
3: Reciprocal Inhibition – when the agonist contracts the antagonist relaxes
4: Eccentric and Concentric Contractions – know the prime mover of every exercise.

A Muscle must cross a joint to make it move

Most skeletal muscles have the primary role of creating action. Therefore, the muscle must cross at least one joint. As the muscle contracts, it shortens, which pulls on the bone and creates movement at the joint.

Muscles work in pairs around a joint – Agonist/ Antagonist pairs

Every muscle that creates a joint action is part of a pair. The biceps brachii is a pair with the Triceps Brachii, and the Quadricpes pair with the Hamstrings. These pairs sit either side of a joint, and abide bythe law of reciprocal inhibition.

Reciprocal Inhibition – when the agonist contracts the antagonist relaxes

Reciprocal inhibition occurs in every muscle pair. This measn that when one muscle contracts the other muscle is relaxing.

Eccentric and Concentric Contractions – know the prime mover of every exercise.

There are two types of muscle contractions you need to know about.

When a muscle is contracted and shortening – we call this a concentric contraction.

When a muscle is contracted and lengthening – we call this an eccentric contraction.
