Clavicle Anatomy Components
-
Sternal End:
- Connects the clavicle to the sternum (breastbone).
- Located at the medial (inner) portion of the clavicle, plays a crucial role in shoulder stability.
-
Shaft:
- The elongated, central portion of the clavicle.
- Provides structural support and serves as an attachment for muscles and ligaments.
-
Acromial End:
- Connects to the acromion of the scapula (shoulder blade).
- Positioned laterally (outer) and involved in forming the shoulder joint.
-
Subclavian Groove:
- A depression located on the inferior (bottom) surface of the clavicle.
- Serves as a pathway for the subclavian artery and vein, important for blood supply to the upper limb.
-
Conoid Tubercle:
- A prominent bony projection located on the clavicle's inferior surface.
- Serves as an attachment point for the conoid ligament, part of the coracoclavicular ligament complex that stabilizes the shoulder joint.
