How Do You Spell CAPITULUM RADII?

Pronunciation: [kɐpˈɪtjʊləm ɹˈe͡ɪdɪˌa͡ɪ] (IPA)

Capitulum radii is a medical term that refers to the head of the radius bone in the forearm. It is pronounced /kəˈpɪtjələm ˈreɪdiˌaɪ/ and the phonetic transcription of the word indicates the correct pronunciation of the individual sounds in the word. The "c" is pronounced like a "k", the "a" is pronounced like an "uh" sound, and the stress is on the second syllable. The "r" at the end of "radii" is signified by the symbol for a schwa followed by an "i" sound.

CAPITULUM RADII Meaning and Definition

1. Capitulum radii refers to the radial head, which is a component of the elbow joint that connects the radius bone of the forearm to the humerus bone of the upper arm. It is the rounded, disc-shaped structure located at the proximal end of the radius bone. The term "capitulum" is derived from the Latin word for "small head" and accurately describes the shape of this structure.

   The capitulum radii plays a crucial role in the movement and stability of the elbow joint. It articulates with the shallow depression called the radial notch on the ulna bone, forming the pivot point for rotation of the forearm. This joint, known as the radiocapitular joint, allows for the supination and pronation of the forearm, which are essential movements for activities such as writing, using a screwdriver, or rotating the hand.

   The structure of the capitulum radii is designed to withstand a considerable amount of stress and provide stability in the joint. It is covered with articular cartilage, a smooth and elastic tissue that reduces friction and facilitates smooth movement of the joint. Ligaments and muscles surrounding the radial head also contribute to its stability and allow for proper functioning of the elbow joint.

   In summary, capitulum radii refers to the rounded disc-shaped structure at the end of the radius bone in the elbow joint. Its main function is to enable the rotation of the forearm, allowing for essential activities and providing stability to the joint.

2. Head of the radius, the disc-shaped upper extremity articulating with the capitellum, or capitulum, of the humerus.

Etymology of CAPITULUM RADII

The term capitulum radii comes from Latin.

Capitulum means small head or little head in Latin. In anatomy, this term is used to refer to a small rounded prominence at the end of a bone, often resembling a head.

Radii is the plural form of radius, meaning ray or spoke in Latin. In anatomy, it refers to the forearm bone located on the thumb side (also called the radius bone).

Therefore, capitulum radii can be translated as small head of the radius bone.
