Plantar: Lateral plantar artery and plantar arch, plantar metatarsal and plantar digital arteries. Nerve: Lateral plantar nerve: Actions: Dorsal: Abducts 2nd through 4th toes, flex metatarsophalangeal joints, and extend phalanges. Plantar: Adduct digits (2-4) and flex metatarsophalangeal joint and extend phalanges. Anatomical terms of muscle
This arrangement of dorsal interossei makes the second toe the midline of the foot, whereas the midline of the hand (marked by dorsal interossei of hand) is in the third finger. [2] Abduction is of little importance in the foot, but, together with the plantar interossei, the dorsal interossei also produce flexion at the metatarsophalangeal joints.
Since the intersseous muscles cross on the metatarsophalangeal joint, then they act on that specific joint and cause adduction of toes III, IV, and V. [1] Adduction itself is not of extreme importance to the toes, but these muscles work together with the dorsal interosseous muscles in flexion of the foot.
A common injury that is normally attributed to the plantaris muscle is a condition called tennis leg. Although pain in the calf can be attributed to a rupture of the plantaris muscle, recent ultrasound research has shown that tennis leg more commonly arises from tears in the musculotendinous junction of the medial gastrocnemius. In one clinical ...
The second dorsal interossei from the medial side of the bone and the third dorsal interossei from the lateral side. The function of the muscle is to spread the toes. [2] The first Plantar interossei muscle originates from the medial side of the base and shaft of the third metatarsal. The function of the muscle is to move the third toe medially ...
Medically, the soles are the site of the plantar reflex, the testing of which can be painful due to the sole's sensitivity. The deep fibular nerve from the common fibular nerve provides the sensory innervation of the skin between the first and second toes and the motor innervation of the muscles of the anterior compartment of the leg and dorsal ...
The flexor digitorum brevis or flexor digitorum communis brevis [1] is a muscle which lies in the middle of the sole of the foot, immediately above the central part of the plantar aponeurosis, with which it is firmly united. Its deep surface is separated from the lateral plantar vessels and nerves by a thin layer of fascia.
Plantar fasciitis is the most common type of plantar fascia injury [10] and is the most common reason for heel pain, responsible for 80% of cases. The condition tends to occur more often in women, military recruits, older athletes, dancers, [ 1 ] people with obesity, and young male athletes.
