Final answer:
The tarsometatarsal joint is a plane joint, a type of synovial joint that allows for gliding movements and contributes to the foot's inversion and eversion.
Step-by-step explanation:
The tarsometatarsal joint is classified as a plane joint, which is a type of synovial joint. These joints allow for gliding movements as the flat or nearly flat surfaces of the bones slide over one another. The tarsometatarsal joint specifically pertains to the articulations between the tarsal bones in the posterior foot (the bones proximal to the metatarsals) and the metatarsal bones (the long bones in the foot). In the context of the foot's movement, the tarsometatarsal joints contribute to the foot's ability to perform inversion and eversion motions, albeit their contribution is subtle compared to that of the larger joints such as the subtalar joint which plays a more significant role in these movements.
