deep external pudendal artery
Branch of the femoral artery, irrigating the external genitalia and upper part of the thigh.

deep femoral vein
Vein carrying blood from the median and posterior parts of the thigh to the femoral vein.

deep fibular nerve
Branch of the common fibular nerve, especially innervating the muscles of the front part of the leg and inner back of the foot.

deep flexor muscle of fingers
Muscle connecting the ulna to the distal phalanges of the fingers; it assists in flexion of the last four fingers and wrist.

deep inguinal lymph nodes
Nodes grouped near the femoral vein, filtering lymph especially from the deep regions of the lower limb, clitoris or penis.

deep lymphatic vessel
Vessel draining lymph from the deep structures and organs of the body.

deep palmar arch
Artery of the palm of the hand, formed by the union of a branch of the ulnar artery and the terminal end of the radial artery; it gives rise to the palmar metacarpal arteries.

deep palmar venous arch
Vein of the palm of the hand, associated with the deep palmar arch.

deep plantar arch
Artery of the sole of the foot, formed by the union of the lateral plantar artery and terminal end of the dorsal artery of the foot; it gives rise to the plantar metatarsal arteries.

deep transverse metacarpal ligament
Ligament connecting the upper part of the second, third, fourth and fifth metacarpals, limiting their movements one to the other.

deferent duct
Canal carrying the spermatozoa of the epididymus to the prostate.

deltoid branch of deep artery of arm
Branch of the deep artery of the arm, irrigating the coracobrachial and deltoid muscles.

deltoid muscle
Thick muscle covering the shoulder, between the clavicle, scapula and humerus; it assists in several movements of the arm (abduction, flexion, extension, rotation).

deltopectoral lymph nodes
Nodes located beneath the clavicle, filtering lymph from the pectoral region.

depressor muscle of angle of mouth
Muscle connecting the mandible to the angle of the mouth, allowing it to be lowered.

depressor muscle of eyebrow
Muscle extending from the frontal bone to the eyebrow, allowing it to lower.

depressor muscle of lower lip
Muscle connecting the mandible to the lower lip, allowing it to be lowered.

descending aorta
Part of the aorta formed by the thoracic aorta and abdominal aorta.

descending branch of lateral circumflex femoral artery
Branch of the lateral circumflex femoral artery, irrigating the thigh muscles.

descending colon
Third segment of the colon, in the left part of the abdomen.

descending genicular artery
Branch of the femoral artery, irrigating the knee and upper part of the leg.

diaphragm
Muscle separating the thorax from the abdomen; its contraction increases the volume of the thoracic cage and lungs.

diaphragmatic surface of spleen
Outer part of the spleen in contact with the diaphragm.

distal phalanx of fourth toe
Last phalanx of the fourth toe, articulating with the medial phalanx.

distal phalanx of great toe
Second and last phalanx of the big toe, articulating with the proximal phalanx.

Last phalanx of the index finger, connected to the medial phalanx.

distal phalanx of little finger
Last phalanx of the little finger, connected to the medial phalanx.

distal phalanx of little toe
Last phalanx of the little toe, articulating with the medial phalanx.

distal phalanx of middle finger
Last phalanx of the middle finger, connected to the medial phalanx.

distal phalanx of ring finger
Last phalanx of the ring finger, connected to the medial phalanx.

distal phalanx of second toe
Last phalanx of the second toe, articulating with the medial phalanx.

distal phalanx of third toe
Last phalanx of the third toe, articulating with the medial phalanx.

distal phalanx of thumb
Last phalanx of the thumb, connected to the proximal phalanx.

dorsal interosseous muscles of hand
Muscles occupying the intermetacarpal spaces located near the dorsum of the hand, connecting the metacarpals to the proximal phalanges of the last four fingers; they allow the fingers to bend and spread apart.
