korakoidiprosessi

The korakoidiprosessi, or coracoid process, is a prominent bony projection located in the shoulder girdle of many vertebrates, including humans. It is a hook-shaped structure that arises from the scapula, or shoulder blade. In humans, it serves as a crucial attachment point for several muscles and ligaments that are vital for shoulder movement and stability.

The primary muscles that insert onto the coracoid process include the short head of the biceps brachii muscle, the coracobrachialis muscle, and the pectoralis minor muscle. The coracoclavicular ligaments, which connect the scapula to the clavicle (collarbone), also attach to the coracoid process. This attachment is significant for maintaining the structural integrity of the shoulder joint.

The coracoid process plays a role in various shoulder movements, such as flexion, adduction, and internal rotation of the arm, due to the muscles that originate or insert on it. Its shape and position allow for efficient leverage and force generation during these actions. Fractures of the coracoid process are relatively uncommon but can occur due to direct trauma to the shoulder. These fractures can lead to significant pain and functional impairment, often requiring surgical intervention. Anatomical variations in the size and shape of the coracoid process exist among individuals.
