Origins and insertions of the arm muscles

Origins and insertions of the arm muscles

In today’s video training, you’ll learn how to remember muscle origin and insertion of the arm muscles ready for your Level 2 or Level 3 Anatomy and Physiology Exam

I’ll show you exactly how to remember complex information about the Triceps Brachii and Biceps Brachii, including the origin and insertion, location, muscle action, and exercises that work the muscles. This means that you use a mix of visual and kinaesthetic learning to commit the facts to your memory and forge out a new neural pathway.

You can then use this same method of learning for all of the other muscles you need to learn for your Level 2 and Level 3 anatomy and physiology exam.

First of all, watch the 7-minute video tutorial and then test your knowledge using the three mock questions at the bottom of this blog.

Watch: Origins and Insertions of the arm muscles

The 5 steps to learn the muscles of the arm

Step 1: Brachii

Wherever you see the word Brachii, it is referring to the arm. So, it is important to break away from the gym speak and use the full name for both the biceps and triceps: Biceps Brachii and Triceps Brachii.

This will avoid confusion on exam day if presented with multiple choice answers that include the Biceps femoris (leg) and biceps brachii (arm).

Step 2: Location

You need to know that the biceps brachii is on the front of the body, and the triceps brachii is on the back of the body. This is true when you stand in an anatomical position with palms facing forwards.

Step 3: Know it in your words

Make sure you know that both muscles cross two joints (shoulder and elbow). Therefore the origins for both the triceps brachii and biceps brachii must be above the shoulder joint. The Insertion must be below the elbow. Point to the origin and insertion on your own body and learn it in your words.

Step 4: Biceps Brachii Detail

Origin:  Short head = Coracoid process of the scapula. Long head = Supragelnoid tubercle of scapula

Insertion: Tuberosity of radius

Joint Action: Supinates the Forearm, Flexes the elbow and Flexes the Shoulder

Step 5: Triceps Brachii Detail

Origin:  Long head = Infraglenoid Tubercle. Lateral and Medial head = Posterior Humerus.

Insertion: Olecranon Process of radius

Joint Action: Extends the elbow, Extends and Adducts the Shoulder
