Metatarsophalangeal joint
Metatarsophalangeal Joint
The Metatarsophalangeal Joint (pronounced: met-uh-tar-so-fuh-LAN-jee-ul joint) is a part of the human anatomy, specifically located in the foot.
Etymology
The term "Metatarsophalangeal Joint" is derived from the combination of two words: "Metatarsal," referring to the long bones in the foot, and "Phalangeal," referring to the bones in the toes.
Anatomy
The Metatarsophalangeal Joint is the articulation between the metatarsal bones and the proximal phalanges of the toes. There are five metatarsophalangeal joints in each foot, one for each toe. These joints play a crucial role in maintaining balance and facilitating movement, particularly during walking and running.
Function
The primary function of the Metatarsophalangeal Joint is to provide flexibility and stability to the foot. They allow for the necessary movements of the toes, such as flexion, extension, abduction, and adduction.
