Protraction vs Retraction of the Scapula, Shoulders | Anatomy Body Movement Terms

Summary

In this video, Ben from registerednessrn.com explains the concepts of protraction and retraction of the scapulae (shoulder blades). Protraction moves the scapulae forward and laterally, while retraction pulls them back toward the midline. He offers a memorable cue: reaching back is retraction, and punching forward is protraction. The serratus anterior muscle, known as the 'boxer's muscle,' assists in these movements. For further learning, viewers can access a free quiz on the website and explore a playlist of anatomy and physiology videos on YouTube, encouraging them to subscribe for more informative content.

Takeaways

• 😀 Protraction involves moving the scapulae forward (anteriorly) and laterally.
• 😀 Retraction is the opposite, moving the scapulae back (posteriorly) toward the midline.
• 😀 Anterolateral movement refers to protraction, while postero medial movement refers to retraction.
• 😀 A simple way to remember these movements: reach back to retract, punch forward to protract.
• 😀 The serratus anterior muscles play a key role in these movements.
• 😀 The serratus anterior is often referred to as the 'boxer's muscle.'
• 😀 Understanding scapular movements is essential for anatomy and physiology studies.
• 😀 The video is part of a larger playlist on anatomy and physiology topics.
• 😀 A free quiz is available on the website to test knowledge of these movements.

Q & A

What are protraction and retraction in relation to the scapulae?

Protraction moves the scapula forward and laterally, while retraction moves it back toward the body's midline.

How can one remember the difference between protraction and retraction?

A simple way to remember is that when you reach back, you retract, and when you punch forward, you protract.

Which muscles assist in the protraction and retraction movements?

The serratus anterior muscles assist with these movements, often referred to as the 'boxer's muscle.'

What direction does the scapula move during protraction?

During protraction, the scapula moves anteriorly and laterally, in an anterolateral direction.

What is the opposite movement of protraction?

The opposite movement of protraction is retraction, which moves the scapula posteriorly and medially.

What type of quiz does registerednessrn.com offer related to this topic?

They offer a free quiz to test knowledge on protraction and retraction.

Where can viewers find additional resources on anatomy and physiology?

Viewers can check out an entire playlist of anatomy and physiology videos available on their YouTube channel.

Why is the serratus anterior muscle called the 'boxer's muscle'?

It is called the 'boxer's muscle' because it plays a crucial role in movements like punching, which involves protraction.

What does the term 'postero medial movement' refer to?

Postero medial movement refers to the backward and inward movement of the scapula during retraction.

What is the main focus of the video presented by Ben?

The video focuses on demonstrating the body movements of protraction and retraction of the scapulae.
