Here are the essential concepts you must grasp in order to answer the question correctly.
Foot Arches
The foot contains three primary arches: the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch. These arches play a crucial role in weight distribution, shock absorption, and overall foot stability during movement. Understanding their structure and function is essential for analyzing foot mechanics and addressing related injuries.

Medial Longitudinal Arch
The medial longitudinal arch runs along the inner side of the foot and is formed by the calcaneus, talus, navicular, cuneiforms, and the first three metatarsals. This arch is vital for maintaining balance and absorbing impact during activities like walking and running. Its height and integrity can significantly affect overall foot function and posture.

Transverse Arch
The transverse arch spans across the foot from the medial to the lateral side, formed by the metatarsal bones and the tarsal bones. This arch helps in distributing weight across the foot and provides stability during lateral movements. A well-functioning transverse arch is essential for efficient gait and preventing foot-related issues.
