The FootThe foot is made up of seven Tarsal bones, five Metatarsal bones, and fourteen Phalanges.
Tarsal Bones
The collective name for this group of bones is the Tarsus. These bones include: Calcaneus, Talus, Navicular, Medial Cuneiform, Intermediate Cuneiform, Lateral Cuneiform, and the Cuboid. The Talus (ankle) articulates with Tibia and Fibula. Together with the Calcaneus (Heel bone), they carry most of the body’s weight.
Metatarsal Bones
The collective term for this group of bones is the Metatarsus, and they make up the middle of the foot.
Phalanges
These are the bones of the toes. Each toe has three phalanges (Proximal, Middle, and Distal), except the Hallux (big toe) which only has two (Proximal, and Distal).
A. Talus Also known as the 'ankle-bone', the Talus articulates with the Tibia (above), Fibula (side), and Calcaneus (below)
B. Navicular
The Navicular is boat-shaped, and can be found between the three Cuneiforms and the Talus.
C. Intermediate Cuneiform
The middle of the three Cuneiform bones, the Intermediate Cuneiform articulates with the second Metatarsal and the Navicular.
D. Medial Cuneiform
The Medial Cuneiform is found on the 'big-toe' side of the foot, and articulates with the first Metatarsal and the Navicular.
E. Distal Phalange
The Distal Phalange is found at the end of each toe.
F. Middle Phalange
The Middle Phalange can be found just below the Distal Phalange. Each toe has one except the Hallux (big-toe) which only has a distal and proximal.
G. Proximal Phalange
This bone articulates with the Middle Phalange (Distal in the Hallux) and the Metatarsal. It can be found at the start of our toe.
H. Metatarsal
There are five Metatarsals in each foot, which are collectively known as the Metatarsus. They are number 1 to 5, starting from the the 'big-toe' side of the foot. It is the head of the first Metatarsal that forms the 'ball' of the foot.
I. Lateral Cuneiform
The Lateral Cuneiform articulates with the second Metatarsal and the Navicular.
J. Cuboid
The Cuboid articulates with the Calcaneus, the Navicular, and the fourth and fifth Metatarsals
K. Calcaneus
Also known as Calcaneum or the 'heel-bone', the Calcaneus articulates with the Talus and Cuboid. It is at the back of the Calcaneus that the Achilles Tendon attaches.
