Glenoid Cavity (Noun)
Meaning
The concavity in the head of the scapula that receives the head of the humerus to form the shoulder joint.
Classification
Nouns denoting body parts.
Examples
- The glenoid cavity is a shallow, saucer-like depression in the scapula that articulates with the head of the humerus.
- The anatomy of the glenoid cavity is complex, with a cartilaginous rim that helps to deepen the socket and increase the stability of the joint.
- The glenoid cavity is positioned at the top of the scapula, forming the socket of the shoulder joint that allows for a wide range of motion.
- The surface of the glenoid cavity is covered with a layer of hyaline cartilage, which helps to reduce friction and absorb shock in the joint.
- In some cases, the glenoid cavity can become damaged or worn down, leading to conditions such as glenoid labral tears or osteoarthritis of the shoulder joint.
