Proximal phalanges
Proximal Phalanges
The Proximal Phalanges (/prɒksɪməl fəˈlændʒiːz/) are the bones in the fingers and toes closest to the metacarpals in the hand and metatarsals in the foot.
Etymology
The term "Proximal Phalanges" is derived from the Greek word "phalanx" which means "line of soldiers", and the Latin word "proximus" which means "nearest". This is because these bones are arranged in a line and are the nearest to the hand or foot.
Anatomy
The proximal phalanges are part of the skeletal system and are classified as long bones. Each finger and toe, except the thumb and big toe, have three phalanges: the proximal, middle, and distal. The thumb and big toe only have a proximal and distal phalanx.
Function
The main function of the proximal phalanges is to provide support and flexibility to the fingers and toes, allowing for a wide range of movements such as gripping and walking. They also play a crucial role in the musculoskeletal system, providing attachment points for muscles and ligaments.
