Serratus anterior

STRUCTURE & FUNCTION

Understand what you see.

Protracts the scapula, holds it against thoracic wall and assists upward rotation.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Digitations on lateral ribs
  2. Passes deep to scapula
  3. Attaches along medial scapular border
02 / KEY STRUCTURES

Point them out.

Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How do you identify serratus anterior?
SUGGESTED ANSWER

Digitations on lateral ribs. Passes deep to scapula. Attaches along medial scapular border.

02What follows long thoracic nerve injury?
SUGGESTED ANSWER

Medial scapular winging, particularly visible when pushing against a wall, with impaired upward rotation.

03What are its nerve roots?
SUGGESTED ANSWER

Long thoracic nerve commonly receives C5–C7 roots.

04What is its main functional or developmental significance?
SUGGESTED ANSWER

Protracts the scapula, holds it against thoracic wall and assists upward rotation. Key structures to recognise: Rib origins; Medial border insertion; Long thoracic nerve.
