Human Foot Bones Medical Content Vector Graphic

The human foot is a complex structure composed of 26 bones, which are categorized into three main groups: the tarsal bones, the metatarsal bones, and the phalanges. Here's a detailed breakdown of these bones:

1. Tarsal Bones (7):

These bones form the rear part of the foot and the ankle. They include:

• Talus: The bone that forms the lower part of the ankle joint and connects with the tibia and fibula.
• Calcaneus: The heel bone, which is the largest tarsal bone and forms the base of the heel.
• Navicular: Located in front of the talus and helps to form the arch of the foot.
• Cuboid: Positioned on the outer side of the foot, it connects with the calcaneus and the fourth and fifth metatarsal bones.
• Medial Cuneiform: Located at the front of the foot, it is the first of three cuneiform bones and is positioned next to the navicular.
• Intermediate Cuneiform: The middle cuneiform bone, located next to the medial cuneiform.
• Lateral Cuneiform: The third cuneiform bone, located on the outer side of the foot.

2. Metatarsal Bones (5):

These bones form the middle part of the foot. Each metatarsal bone is numbered from one to five, starting from the big toe (hallux) side:

• First Metatarsal: The largest and strongest, supporting the big toe.
• Second Metatarsal: The longest of the metatarsals.
• Third Metatarsal: Positioned in the middle of the foot.
• Fourth Metatarsal: Located towards the outer side of the foot.
• Fifth Metatarsal: The smallest metatarsal bone, located on the outer edge of the foot, where the little toe is.

3. Phalanges (14):

These bones make up the toes. Each toe has a specific arrangement of phalanges:

• Big Toe (Hallux): Has 2 phalanges (proximal and distal).
• Other Toes: Each has 3 phalanges (proximal, middle, and distal).
