They can be divided into those situated on the dorsum of the foot, and those in the sole of the foot. The plantar and dorsal interossei comprise the fourth and final plantar muscle layer. The second to fourth interossei attach to the lateral sides of the proximal phalanxes of digits two to four. Le second but intervient après un travail de Kagelmacher, Germain déborde sur le côté gauche et frappe directement et malicieusement du pied gauche, surprenant le gardien de l’ACAA. Le 8 juin 2003, Zanetti marque un but lors de la victoire de l’Albiceleste contre le Japon. They act collectively to stabilise the arches of the foot and individually to control movement of the digits. Intrinsic muscles are located within the foot and are responsible for the fine motor actions of the foot, for example movement of individual digits. Attachments: Originates from the medial tubercle of the calcaneus and the plantar aponeurosis. The plantar aponeurosis has been cut to reveal the underlying flexor digitorum.
Attachments: Originates from the medial and lateral tubercles of the calcaneus and the plantar aponeurosis. The bones of the foot provide mechanical support for the soft tissues; helping the foot withstand the weight of the body whilst standing and in motion. The abductor hallucis muscle is located on the medial side of the sole, where it contributes to a small soft tissue bulge. The abductor digiti minimi muscle is located on the lateral side of the foot. The third layer contains three muscles. The first layer of plantar muscles. The second layer of the plantar muscles. The first muscle attaches to the medial side of the proximal phalanx of the second digit. It attaches to the medial base of the proximal phalanx of the great toe. This can cause aching, numbness and paraesthesia on the medial side of the sole of the foot. In this article, we shall look at the anatomy of the bones of the foot – their bony landmarks, articulations, and clinical correlations. Attachments: – Oblique head – originates from the bases of the 2nd, 3rd, and 4th metatarsals. It consists of an oblique and transverse head. Transverse head – originates from the plantar ligaments of the metatarsophalangeal joints.
Actions: Flexion at the metatarsophalangeal joints and extension at the interphalangeal joints. These comprise the hindfoot, forming the bony framework around the proximal ankle and heel. It attaches to the base of the proximal phalanx of the great toe. The tarsal bones of the foot are organised into three rows: proximal, intermediate, and distal. The flexor hallucis brevis and adductor hallucis are associated with movements of the great toe. The quadratus plantae is a flat, square-shaped muscle with two heads of origin. It is homologous with the abductor digiti minimi of the hand. The flexor digitorum brevis muscle is located laterally to the abductor hallucis. Phalanges – the bones of the toes. Attaches to the medial sides of the phalanges of digits three to five. There are three plantar interossei, which are located between the metatarsals. There are four dorsal interossei, which are located between the metatarsals. The fibres converge into a single muscle belly, which attaches to the base of the proximal phalanx of the great toe. Each arises from a single metatarsal. They are each located medial to their respective tendon of the flexor digitorum longus. Each arises from two metatarsals.
The extensor digitorum brevis is a small, thin muscle which lies underneath the long extensor tendons of the foot. The flexor digiti minimi brevis muscle is located on the lateral side of the foot, underneath the metatarsal of the little toe. The remaining muscle, the flexor digiti minimi brevis, moves the little toe. It attaches to the lateral base of the proximal phalanx of the 5th digit. Actions: Extension of the great toe. Actions: Abduction and flexion of the great toe. ↑ (en) Curtis Stephen, « David Adjaye : Breaking Barriers and Building Community », The Crisis, janvier 2006, p. The muscle can become compressed during repetitive eversion of the foot, which may occur in some sports such as gymnastics. The flexor hallucis brevis muscle is located on the medial side of the foot. Innervation: – Medial lumbrical – medial plantar nerve. Innervation: Medial plantar nerve. Innervation: Deep fibular nerve.
