The First Metatarsal Bone (os metatarsale I; metatarsal bone of the great toe) is remarkable for its great thickness, and is the shortest of the metatarsal bones. The body is strong, and of...

Bone
2nd Metatarsal Bone
The Second Metatarsal Bone (os metatarsale II) is the longest of the metatarsal bones, being prolonged backward into the recess formed by the three cuneiform bones. Its base is broad above, narrow...
4th Metatarsal Bone
The Fourth Metatarsal Bone (os metatarsale IV) is smaller in size than the preceding; its base presents an oblique quadrilateral surface for articulation with the cuboid; a smooth facet on the...
5th Metatarsal Bone
The Fifth Metatarsal Bone (os metatarsale V) is recognized by a rough eminence, the tuberosity, on the lateral side of its base. The base articulates behind, by a triangular surface cut obliquely in...
3rd Metatarsal Bone
The Third Metatarsal Bone (os metatarsale III) articulates proximally, by means of a triangular smooth surface, with the third cuneiform; medially, by two facets, with the second metatarsal; and...
Intermediate Cuneiform Bone
The Second Cuneiform Bone (os cuneiforme secundum; middle cuneiform), the smallest of the three, is of very regular wedge-like form, the thin end being directed downward. It is situated between the...
Medial Cuneiform
The First Cuneiform Bone (os cuneiform primum; internal cuneiform) is the largest of the three cuneiforms. It is situated at the medial side of the foot, between the navicular behind and the base of...
Cuboid
The Cuboid Bone (os cuboideum) is placed on the lateral side of the foot, in front of the calcaneus, and behind the fourth and fifth metatarsal bones. It is of a pyramidal shape, its base being...
Lateral Cuneiform bone
The Third Cuneiform Bone (os cuneiforme tertium; external cuneiform), intermediate in size between the two preceding, is wedge-shaped, the base being uppermost. It occupies the center of the front...
Navicular – Foot
The Navicular Bone (os naviculare pedis; scaphoid bone) is situated at the medial side of the tarsus, between the talus behind and the cuneiform bones in front. Surfaces The anterior surface is...
Calcaneus
The Calcaneus (os calcis) is the largest of the tarsal bones. It is situated at the lower and back part of the foot, serving to transmit the weight of the body to the ground, and forming a strong...
Talus – Astragalus
The Talus (astragalus; ankle bone) is the second largest of the tarsal bones. It occupies the middle and upper part of the tarsus, supporting the tibia above, resting upon the calcaneus below,...
Fibula
The fibula is the slender bone located on the lateral side of the leg (Picture 1). The fibula does not bear weight. It serves primarily for muscle attachments and thus is largely surrounded by...
Tibia
The tibia (shin bone) is the medial bone of the leg and is larger than the fibula, with which it is paired. The tibia is the main weight-bearing bone of the lower leg and the second longest bone of...
Femur
The femur, or thigh bone, is the single bone of the thigh region (Picture 1). It is the longest and strongest bone of the body, and accounts for approximately one-quarter of a person’s total height....
