The medical term for abnormal swelling of the first metatarsophalangeal joint is "hallux abducto valgus" or more commonly known as "bunion".
tar·so·met·a·tar·sal joints [TA] the three synovial joints between the tarsal and metatarsal bones, consisting of a medial joint between the first cuneiform and first metatarsal, an intermediate joint between the second and third cuneiforms and corresponding metatarsals, and a lateral joint between the cuboid and fourth and fifth metatarsals.

The first metatarsal bone is in direct contact with the medial cuneiform bone in the foot.
The tibialis anterior muscle inserts onto the base of the first metatarsal and the medial cuneiform bone. It is responsible for dorsiflexion of the foot and inversion of the ankle.
The tibialis anterior inserts into the medial cuneiform bone and the base of the first metatarsal bone in humans.
Plural of metatarsal is metatarsus, they are the five long bones of the foot, and metacarpals are that of the hand
Distal to the metatarsals are the phalanges. The great toe (hallux) has two phalanges where as all of the other toes have three each. The proximal phalanges attach the the metatarsals via the metatarsal phalangeal joints. Proximal to the metatarsals are the tarsals. The first, second, and third cuneiforms articulate with the first, second and third metatarsals. The fourth metatarsal articulates with the cuboid and the head of the fifth metatarsal is its own projection that can be felt on the lateral foot.
in the first and second metatarsal.
The first metatarsal typically has a sesamoid bone inserted at its base, specifically beneath the head of the first metatarsal. These sesamoid bones, known as the medial and lateral sesamoids, help with the mechanics of the foot, providing leverage and absorbing weight during activities like walking and running. They also play a role in protecting the tendons that run to the big toe.
Inflammation of this area causes a decrease in motion with associated discomfort in the joint between the big toe and the first metatarsal.
it is a bone that connects to the tarsal.
of the medial longitudinal arch, beneath the sustentaculum tali, and proximal to the first metatarsal head.
