(fleks'ŏr dij-i-tō'rŭm prō-fŭn'dŭs mŭs'ĕl)
Origin, anterior surface of upper third of ulna; insertion, by four tendons, piercing those of the superficialis, into base of distal phalanx of each finger; action, flexes distal interphalangeal joint of fingers; nerve supply, ulnar and median (anterior interosseous muscle).
Synonym(s): musculus flexor digitorum profundus [TA] .

flexor digitorum profundus muscle

Forearm muscle. Origin: proximal three-fourths of ulna. Insertion: distal phalanges of fingers (digits 2-5). Nerve: ulnar, median (C8-T1). Action: flexes distal finger joints, aids in wrist flexion.
