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 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 ...
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 most superficial muscle in the thenar group is the abductor pollicis brevis. The abductor brings the thumb away from the other four fingers. The flexor pollicis brevis, which lies next to the abductor, will flex the thumb, curling it up in the palm. The opponens pollicis lies deep to abductor pollicis brevis.
It's time for a fitness vocab lesson. Today's words are adduction and abduction. Understanding these practically identical terms can go a long way toward helping you fine-tune your form, avoid ...
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 flexor digiti minimi brevis arises from the hamulus of the hamate bone and the palmar surface of the flexor retinaculum of the hand. It is inserted into the medial side of the base of the proximal phalanx of digit V. It is separated from the abductor digiti minimi, at its origin, by the deep branches of the ulnar artery and the ulnar nerve ...
The opponens digiti minimi (opponens digiti quinti in older texts) is a muscle in the hand.It is of a triangular form, and placed immediately beneath the palmaris brevis, abductor digiti minimi and flexor digiti minimi brevis.
