Superficial palmar arch

The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery.

See Hand and Superficial palmar arch

Syndactyly

Syndactyly is a condition wherein two or more digits are fused together.

See Hand and Syndactyly

Thenar eminence

The thenar eminence is the mound formed at the base of the thumb on the palm of the hand by the intrinsic group of muscles of the thumb.

See Hand and Thenar eminence

Thumb

The thumb is the first digit of the hand, next to the index finger.

See Hand and Thumb

Trapezium (bone)

The trapezium bone (greater multangular bone) is a carpal bone in the hand.

See Hand and Trapezium (bone)

Trapezoid bone

The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans.

See Hand and Trapezoid bone

Treeshrew

The treeshrews (also called tree shrews or banxrings) are small mammals native to the tropical forests of South and Southeast Asia.

See Hand and Treeshrew

Triquetral bone

The triquetral bone (also called triquetrum, pyramidal, three-faced, and formerly cuneiform bone) is located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones.

See Hand and Triquetral bone

Ulna

The ulna or ulnar bone (ulnae or ulnas) is a long bone in the forearm stretching from the elbow to the wrist.

See Hand and Ulna

Ulnar artery

The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspects of the forearm.

See Hand and Ulnar artery

Ulnar collateral ligament injury of the thumb

Gamekeeper's thumb (also known as skier's thumb or UCL tear) is a type of injury to the ulnar collateral ligament (UCL) of the thumb.

Ulnar nerve

The ulnar nerve is a nerve that runs near the ulna, one of the two long bones in the forearm.

See Hand and Ulnar nerve

Uterus

The uterus (from Latin uterus,: uteri) or womb is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more embryos until birth.

See Hand and Uterus

Vertebrate

Vertebrates are deuterostomal animals with bony or cartilaginous axial endoskeleton — known as the vertebral column, spine or backbone — around and along the spinal cord, including all fish, amphibians, reptiles, birds and mammals.

See Hand and Vertebrate

Wrist

In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; "The wrist contains eight bones, roughly aligned in two rows, known as the carpal bones." (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. Hand and wrist are upper limb anatomy.
