Carpus
Carpus
Carpus (pronounced: /ˈkɑːrpəs/) is a term used in anatomy to refer to the eight small bones that make up the wrist in humans and primates. The term is derived from the Greek word 'karpos', which means 'wrist'.
Etymology
The term 'Carpus' is derived from the Greek word 'karpos', which translates to 'wrist'. The word was adopted into Latin as 'carpus', and it has been used in English since the late 16th century.
Anatomy
The carpus is made up of two rows of carpal bones. The proximal row (closest to the forearm) includes the scaphoid, lunate, triquetrum, and pisiform bones. The distal row (closest to the fingers) includes the trapezium, trapezoid, capitate, and hamate bones. These bones are connected by ligaments and allow for the complex movements of the wrist.
