Shoulder

Medial border of the scapula

Margo medialis scapulae

How to find it
Let the arm hang relaxed. This border runs from top to bottom parallel to the spinous processes, about a hand width to their side. Ask for a slight retraction of the shoulders and it stands out more clearly along its whole length.
What you use it for
Attachment of the rhomboids and serratus anterior. If the border lifts away from the chest wall you have a winged scapula, usually from a long thoracic nerve palsy.
