The muscular branches supply muscles on the medial side of the sole, including the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis, and the first lumbrical; those for the abductor hallucis and flexor digitorum brevis arise from the trunk of the nerve near its origin and enter the deep surfaces of the muscles; the branch of the flexor hallucis brevis springs from the ...
The abductor digiti minimi (abductor minimi digiti, abductor digiti quinti) is a muscle which lies along the lateral (outer) border of the foot, [1] and is in relation by its medial margin with the lateral plantar artery, vein and nerves. Its homolog in the arm is the abductor digiti minimi muscle in the hand.
The medial plantar nerve supplies: the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical.Cutaneous distribution of the medial plantar nerve is to the medial sole and medial three and one half toes, including the nail beds on the dorsum (like the median nerve in the hand).
The abductor digit minimi develops at an early stage from an ulnar muscle primordium of the superficial layer of the original undifferentiated mesenchyme of the hand, together with the flexor digitorum superficialis (medial primordia) and the abductor pollicis brevis (radial). In contrast, the remaining hypothenar muscles are derived from the ...
It passes between the abductor hallucis and flexor digitorum brevis to divide further into branches. Its distribution resembles to that of the distribution of median nerve in the hand. Its muscular branches supply the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical. Cutaneous distribution of ...
The muscles of hypothenar eminence are from medial to lateral: Opponens digiti minimi; Flexor digiti minimi brevis; Abductor digiti minimi; The intrinsic muscles of hand can be remembered using the mnemonic, "A OF A OF A" for, Abductor pollicis brevis, Opponens pollicis, Flexor pollicis brevis (the three thenar muscles), Adductor pollicis, and the three hypothenar muscles, Opponens digiti ...
The second, third, and fourth dorsal interossei have insertions both proximally on the base of the metacarpal and hood, and distally on the lateral bands and central tendon of the extensor mechanism. The abductor digiti minimi, effectively the "fifth dorsal interosseus" or the dorsal interosseus of the little finger, has only a proximal insertion.
The flexor digiti minimi brevis (flexor brevis minimi digiti, flexor digiti quinti brevis) lies under the metatarsal bone on the little toe, and resembles one of the interossei. It arises from the base of the fifth metatarsal bone , and from the sheath of the fibularis longus ; its tendon is inserted into the lateral side of the base of the ...
