In human anatomy, the abductor digiti minimi (abductor minimi digiti, abductor digiti quinti, ADM) is a skeletal muscle situated on the ulnar border of the palm of the hand.
Furthermore, where is abductor Digiti Minimi muscle?
The abductor digiti minimi (abductor minimi digiti, abductor digiti quinti) is a muscle which lies along the lateral (outer) border of the foot, 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.
Also Know, what is the origin of abductor Digiti Minimi? Abductor digiti minimi muscle originates from the plantar aponeurosis, lateral and medial processes of calcaneal tuberosity and the area between them. It courses anteriorly through the lateral part of the foot, giving off a tendon that inserts to the base of proximal phalanx of 5th digit and 5th metatarsal bone.
Also, what does the abductor Digiti Minimi do?
Its main function is to pull the little finger away from the other fingers (abduction). It also plays an important role when the hand grasps something tightly. It helps flex the joint of the first knuckle. Nerve functions are supplied by the deep branch of the ulnar nerve.
Why does my abductor Digiti Minimi hurt?
The abductor digiti minimi is often injured due to its location during physical activity where a person is upright. This muscle can play a role in plantar fasciitis, inflammation of the connective tissue in the sole of the foot.
