Ligaments Tarsal-Metatarsal Dorsal

Dorsal tarsometatarsal ligaments: anatomical description and functions

The dorsal tarsometatarsea ligaments (l. tarsometatarsea dorsalia, pna, bna, jna) are an important component of the anatomy of the foot of mammals, including humans. These ligaments play an important role in maintaining foot stability and ensuring proper biomechanics when walking and running.

The anatomical ligaments in the dorsum of the foot are part of a complex network of ligaments that connect the bones of the foot and provide support and stability. The dorsal tarsometatarsal ligaments start from the anterior surface of the metatarsal bone and attach to the metatarsal bones (middle bones located between the bones of the foot and the toes).

The dorsal tarsometatarsal ligaments are made up of several components, including the calcaneal-epicondylar ligament (pna), the tubercle-epicondylar ligament (bna), and the malleol-epicondylar ligament (jna). These ligament components play different roles in supporting the foot and providing stability.

The calcaneoepicondylar ligament (pna) connects the heel bone to the epicondyles of the metatarsals and provides support to the forefoot. The tubercle-epicondylar ligament (bna) connects the metatarsal tubercles to the metatarsal epicondyles and provides stability to the hindfoot. The ankle-epicondylar ligament (jna) connects the ankle to the epicondyles of the metatarsals and provides support to the midfoot.

These ligaments work together to provide stability to the foot during walking and running. They also help distribute body weight across the foot and reduce stress on individual bones and joints.

In conclusion, the dorsal tarsometatarsal ligaments are an important component of the anatomy of the foot, playing an important role in maintaining foot stability and proper biomechanics during walking and running. Understanding their anatomy and function can help diagnose and treat foot injuries and diseases, as well as develop exercises and techniques to improve foot biomechanics.

Ligaments of the tarsus - dorsal metatarsal (lat. l. tarsometa-tarsea dorsalia, etc.) - are located at the dorsal surface of the tarsus in a recess, behind the protrusions of the heel bone. One of the ligaments connects the outer edge of the talus to the posterior surface of the 5th metatarsal. The anterior ligament attaches the first metatarsal bone to the base of the heel, the posterior one - to the lateral part of the head of the talus, and in the upper part of the anterior surface of the talus - the third and fourth metatarsal bones.

The function of the ligaments is to support the joints of the tarsus and
