Anatomical terminology

The arcuate artery of the foot gives off the second, third, and fourth dorsal metatarsal arteries, which run forward upon the corresponding Interossei dorsales; in the clefts between the toes, each divides into two dorsal digital branches for the adjoining toes.

At the proximal parts of the interosseous spaces these vessels receive the posterior perforating branches from the plantar arch, and at the distal parts of the spaces they are joined by the anterior perforating branches, from the plantar metatarsal arteries.

The fourth dorsal metatarsal artery gives off a branch which supplies the lateral side of the fifth toe.

The first dorsal metatarsal artery runs forward on the first Interosseous dorsalis.

<span class="mw-page-title-main">Foot</span> Anatomical structure found in vertebrates

The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.

<span class="mw-page-title-main">Human leg</span> Lower extremity or limb of the human body (foot, lower leg, thigh and hip)

The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur, tibia, and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front) are between the knee and foot.

In human anatomy, the dorsalis pedis artery is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space. It carries oxygenated blood to the dorsal side of the foot. It is useful for taking a pulse. It is also at risk during anaesthesia of the deep peroneal nerve.

<span class="mw-page-title-main">Tibial nerve</span> Branch of the sciatic nerve

The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.

In human anatomy, the dorsal interossei of the foot are four muscles situated between the metatarsal bones.

In human anatomy, plantar interossei muscles are three muscles located between the metatarsal bones in the foot.

<span class="mw-page-title-main">Deep fibular nerve</span> Type of nerve

The deep fibular nerve begins at the bifurcation of the common fibular nerve between the fibula and upper part of the fibularis longus, passes infero-medially, deep to the extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior tibial artery above the middle of the leg; it then descends with the artery to the front of the ankle-joint, where it divides into a lateral and a medial terminal branch.

<span class="mw-page-title-main">Medial plantar nerve</span> Larger of the two terminal divisions of the tibial nerve

The medial plantar nerve is the larger of the two terminal divisions of the tibial nerve, which accompanies the medial plantar artery.

<span class="mw-page-title-main">Lateral plantar artery</span>

The lateral plantar artery, much larger than the medial, passes obliquely lateralward and forward to the base of the fifth metatarsal bone.

<span class="mw-page-title-main">Plantar metatarsal arteries</span>

The plantar metatarsal arteries are four in number, arising from the convexity of the plantar arch. They run forward between the metatarsal bones and in contact with the Interossei. They are located in the fourth layer of the foot.

<span class="mw-page-title-main">Medial plantar artery</span>

The medial plantar artery, much smaller than the lateral plantar artery, passes forward along the medial side of the foot.

<span class="mw-page-title-main">Deep plantar artery</span>

The deep plantar artery descends into the sole of the foot, between the two heads of the 1st interosseous dorsalis, and unites with the termination of the lateral plantar artery, to complete the plantar arch.

<span class="mw-page-title-main">Tarsometatarsal joints</span> Part of the human foot

The tarsometatarsal joints are arthrodial joints in the foot. The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym of Lisfranc joint is 18th–19th-century surgeon and gynecologist Jacques Lisfranc de St. Martin.

<span class="mw-page-title-main">Intermetatarsal joints</span>

The intermetatarsal joints are the articulations between the base of metatarsal bones.

In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta:

The arcuate artery of the foot arises from dorsalis pedis slightly anterior to the lateral tarsal artery, specifically over the naviculocuneiform joint; it passes lateralward, over the bases of the lateral four metatarsal bones, beneath the tendons of the extensor digitorum brevis, its direction being influenced by its point of origin; and it terminates in the lateral tarsal artery. It communicates with the plantar arteries through the perforating arteries of the foot.

The plantar arch is a circulatory anastomosis formed from:

<span class="mw-page-title-main">Fifth metatarsal bone</span> Long bone in the foot

The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand.

<span class="mw-page-title-main">Fourth metatarsal bone</span>

The fourth metatarsal bone is a long bone in the foot. It is smaller in size than the third metatarsal bone and is the third longest of the five metatarsal bones. The fourth metatarsal is analogous to the fourth metacarpal bone in the hand

The first dorsal metatarsal artery is a small artery on the back of the foot. It runs forward on the first interosseous dorsalis muscle, and at the cleft between the great and second toes divides into two branches, one of which passes beneath the tendon of the extensor hallucis longus muscle, and is distributed to the medial border of the great toe; the other bifurcates to supply the adjoining sides of the great and second toes.
