The metatarsus consists of the five long bones of the foot, which are numbered from the medial side (ossa metatarsalia I.

These are analogous to the metacarpals of the hand.

Specifically, the bones are:

• First metatarsal bone
• Second metatarsal bone

Common characteristics of the metatarsal bones

• The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The first metatarsal bone is the bone in the body of the foot just behind the big toe The second metatarsal bone is the longest of the Metatarsal bones being prolonged backward into the recess formed by the three Cuneiform bones Its base is broad The third Metatarsal bone articulates proximally by means of a triangular smooth surface with the Third cuneiform; medially by two facets with the Second The fourth Metatarsal bone is smaller in size than the third its base presents an Oblique Quadrilateral surface for articulation with the cuboid The fifth Metatarsal bone is recognized by a rough eminence the tuberosity on the lateral side of its base The name Phalanx (plural phalanges) is commonly given to the Bones that form Fingers and Toes In Primates such as Humans

• The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by its sides with the contiguous metatarsal bones: its dorsal and plantar surfaces are rough for the attachment of ligaments. In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species In Anatomy, the dorsum is the upper side of animals that typically run fly or swim in a horizontal position and the back side of animals (like humans that walk upright In Anatomy, the term ligament is used to denote three different types of structures Fibrous tissue that connects Bones to other bones

• The head or anterior extremity presents a convex articular surface, oblong from above downward, and extending farther backward below than above.

• Its sides are flattened, and on each is a depression, surmounted by a tubercle, for ligamentous attachment. In anatomy a tubercle is a round Nodule, small Eminence, or Warty outgrowth found on Bones skin or within the lungs in Tuberculosis

• Its plantar surface is grooved antero-posteriorly for the passage of the flexor tendons, and marked on either side by an articular eminence continuous with the terminal articular surface. In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species A tendon (or sinew) is a tough band of Fibrous connective tissue that usually connects Muscle to Bone and is capable of withstanding tension

Articulations

The base of each metatarsal bone articulates with one or more of the tarsal bones, and the head with one of the first row of phalanges.

• The first metatarsal articulates with the first cuneiform. The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms.
• the second with all three cuneiforms.
• the third with the third cuneiform.
• the fourth with the third cuneiform and the cuboid.
• The fifth with the cuboid.

Injuries

The metatarsal bones are often broken by soccer players. Association football, more commonly known as football or soccer, is a Team sport played between two teams of eleven players and is widely considered These and other recent cases have been attributed to the modern lightweight design of football boots, which give less protection to the foot. The items of Footwear worn while playing Football are called football boots in British English.

Stress fractures are thought to account for 16% of injuries related to sports preparation, and the metatarsals are most often involved. These fractures are commonly called march fractures, as they are commonly diagnosed among military recruits after long marches. They are also common among road runners, and even skimboarders. The second and third metatarsals are fixed while walking, thus these metatarsals are common sites of injury. The fifth metatarsal may be fractured if the foot is oversupinated during locomotion. Supination is a position of either the Forearm or foot in the forearm when the palm faces anteriorly or faces up (when the arms are unbent and at the sides ^[1]
