A thick, flat, deep muscle in the posterior compartment of the lower leg. The tibialis posterior has extensive origins on the posterior, proximal surface of the tibia, fibula, and interosseus membrane. Its insertion is on the tarsal and metatarsal bones via a tendon that passes behind the medial malleolus and under the arch of the foot. Its primary actions are plantar flexion and inversion. It also helps to stabilize the longitudinal arch, especially during skating.

In anatomy, the 1st ray refers to the first metatarsal bone and the associated bones of the foot, including the medial cuneiform bone. It is essential for weight-bearing and plays a significant role in maintaining the arch and stability of the foot. Dysfunction or deformity of the 1st ray can contribute to conditions like hallux valgus (bunions) or flatfoot.

No the little toe is lateral to the big toe, and so the big toe is medial to the little toe.
It'a called the 'medial longitudinal arch'
The medial longitudinal arch, the lateral longitudinal arch, and the transverse arch and the metatarsal arch are the four arches of the foot. The ML goes from heel to hallux (heel to big toe), the LL goes from the heel to the little toe, and the TA goes across the bottom of them and the metatarsal arch, formed by muscles and ligaments.
== == There are three arches in the foot, not one. They are the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch. The ML goes from heel to hallux (heel to big toe), the LL goes from the heel to the little toe, and the TA goes across the bottom of them. There is just 1 arch in a foot check out this websit to learn more: http://orthoinfo.aaos.org/fact/thr_report.cfm?Thread_ID=381&topcategory=Foot
plantar surface.
The medial side of a shoe is the side that the foot arch is present on. When a pair of shoes are worn the medial sides face each other. The lateral side (the outside of the shoe) face away from the body.
To provide dynamic support of a longitudinal arch of the foot, resisting those forces that act momentarly to spread the arch during walking and running.
The anterior transverse arch of the foot is where the metatarso-phalangeal articulation become an arch. .The transverse arch offload pressure from the mid phalanges and places the load on the 1st and 5th, for effective weight distribution.
It's the arch in a medial to lateral direction on the plantar surface of the foot(concave). The distal intertarsal joints make up the arch. The arch/bones of the arch have a primary function of providing stability across the midfoot. A bit more abstract: They also provide aid in pronation/supination OR inversion/eversion if you would rather, by maintaining stability during those motions.

or you may be thinking of your foot arch
A foot arch is the part of your foot between the toes or front of your foot, and the heel of the foot. If you have a high arch and do not wear proper shoes with a good arch support you can experience strong pain in this area. You may even want to consider shoe inserts.
