CAPITELLUM Meaning and
Definition
-
The term "capitellum" refers to a small, rounded protrusion or knobby structure found at the end of a bone. It is predominantly associated with the human anatomy, specifically within the skeletal system. The capitellum is commonly observed in long bones, such as the humerus, and represents one of the distinct articular surfaces that contribute to the formation of a joint.
Functionally, the capitellum plays a crucial role in facilitating smooth and effective articulation between adjacent bones. In conjunction with other articular surfaces, it helps to establish a joint's range of motion and stability. Due to its rounded shape, the capitellum enables rotation, gliding, and pivoting movements at the joint, promoting flexibility and coordination.
Moreover, the capitellum is often covered by a layer of smooth, cartilaginous tissue known as articular cartilage. This protective covering assists in reducing friction during joint movement, as well as absorbing shock and distributing loads evenly. However, in certain medical conditions or injuries, such as fractures or degenerative diseases, the capitellum can become damaged or compromised, leading to pain, limited mobility, and functionality impairment.
In summary, the capitellum is a small-shaped projection found at the end of a bone, serving as a vital component in the formation of a joint. It allows for various types of movement and plays a crucial role in joint function, whilst being covered by articular cartilage to protect it from wear and tear.
