The spelling of "articulationes metacarpophalangeae" can be a challenge due to its length and complex Latin roots. The word refers to the joint connecting the bones of the hand and fingers. The correct pronunciation is /ɑr.tɪ.kjuː.lɑː.ˈʃi.oʊ.niːz ˌmɛ.təˌkɑr.poʊˌfæ.lænˈdʒiːi/. The IPA phonetic transcription breaks down the word into its individual sounds, making it easier to understand and pronounce correctly. Practice and familiarity with medical terminology are important for accurate communication in healthcare settings.
Articulationes metacarpophalangeae is a Latin term that translates to "metacarpophalangeal joints" in English. It is a medical or anatomical term used to refer to the joints that connect the metacarpal bones of the hand with the phalanges (finger bones).
The human hand consists of five metacarpal bones, each connected to one of the five digits: the thumb and four fingers. The articulationes metacarpophalangeae are the hinge-like synovial joints between the rounded heads of the metacarpal bones and the base of the proximal phalanx bones. They allow for a range of movements in the fingers, including flexion (bending), extension (straightening), abduction (spreading the fingers apart), adduction (bringing the fingers together), and opposition (opposing the thumb to the fingers).
These joints play a crucial role in motor functions, providing dexterity and precision to the hand. The articulationes metacarpophalangeae are surrounded by a capsule lined with synovial membrane, which produces synovial fluid to lubricate the joint and reduce friction during movement. Ligaments strengthen and stabilize the joints, preventing excessive movements or dislocations.
Diseases or injuries affecting the articulationes metacarpophalangeae can lead to pain, stiffness, swelling, and limited hand function. Medical professionals, such as orthopedic surgeons or hand therapists, may diagnose and treat conditions like arthritis, sprains, fractures, or tendon injuries that can affect these joints. Rehabilitation exercises, splinting, medications, or surgical interventions may be utilized to restore or improve the function of the articulationes metacarpophalangeae.

The term "articulationes metacarpophalangeae" comes from Latin root words. Here is the breakdown:
1. "Articulationes" - This is the plural form of the Latin word "articulatio" which means "joint". In this context, it refers to the joints that connect the bones of the hand.
2. "Metacarpo-" - This is a combining form derived from the Latin word "metacarpus" which means "metacarpal bone". Metacarpal bones are the long bones present in the palm of the hand.
