The scapula, also known as the shoulder blade, is a triangular-shaped bone located in the upper back.
Here's a more detailed breakdown:
-
Definition: The scapula (plural: scapulae) is a flat bone that connects the humerus (upper arm bone) with the clavicle (collarbone).
-
Location: It rests on the posterior (back) aspect of the rib cage.
-
Shape: Roughly triangular.
-
Function: The scapula serves as an attachment point for numerous muscles of the shoulder, back, chest, and neck. These muscles enable a wide range of arm and shoulder movements. It also articulates with the humerus to form the glenohumeral (shoulder) joint.
-
Importance: The scapula is vital for proper shoulder function and movement. Dysfunction or injury to the scapula or surrounding muscles can lead to pain and limited range of motion.
-
Example: Think of raising your arm to throw a ball. The scapula rotates and protracts, allowing the arm to move freely. Without proper scapular movement, the arm's range of motion would be significantly restricted.
In summary, the scapula is a crucial bone in the shoulder region, providing structural support and serving as an attachment site for muscles responsible for arm and shoulder movement.
