The ulnar artery enters the hand [blank_start]anteriorly[blank_end] to the flexor retinaculum and [blank_start]laterally[blank_end] to the ulnar nerve via [blank_start]Guyon's canal[blank_end]. It gives rise to a [blank_start]deep palmar branch[blank_end] before continuing laterally across the palm as the [blank_start]superficial palmar arch[blank_end] which gives rise to the [blank_start]digital arteries[blank_end].
The radial artery enters the hand [blank_start]dorsally[blank_end], crossing the [blank_start]floor[blank_end] of the anatomical snuffbox. It supplies branches to the thumb, [blank_start]index[blank_end] finger and [blank_start]superficial[blank_end] palmar arch and continues as the [blank_start]deep[blank_end] palmar arch which supplies the digits and wrist joint.- Aanteriorly

54Drag and drop the correct answers to describe the ligaments of the hand.
The flexor retinaculum is a thick strip of connective tissue on the [blank_start]palmar[blank_end] aspect of the hand extending between the pisiform and [blank_start]hook of hamate[blank_end] to the trapezium and [blank_start]scaphoid[blank_end]. It forms the roof of [blank_start]the carpal tunnel[blank_end].
The extensor retinaculum is a similar thickening of the fascia on the [blank_start]dorsal[blank_end] aspect of the hand. The retinaculae prevent [blank_start]bowstringing[blank_end] of the tendons that insert in the hand.
The plamar/volar plates occur on the [blank_start]palmar side[blank_end] of the metacarpophalangeal and interphalangeal joints. They prevent excessive [blank_start]extension[blank_end] of the digits.
The collateral ligaments are found on the [blank_start]medial and lateral[blank_end] sides of the metacarpophalangeal and interphalangeal joints. The are taut during flexion to [blank_start]limit[blank_end] abduction and lax during extension to [blank_start]allow[blank_end] abduction- Apalmar

56Drag and drop the correct answers to describe the flexor tendons in the hand.
The flexor tendons include the tendons of flexor digitorum profundus and flexor digitorum superficialis. All [blank_start]8[blank_end] of these tendons are protected by a [blank_start]common[blank_end] flexor sheath in the hand which then fans out into digital [blank_start]synovial[blank_end] sheaths in each finger. Each tendon of flexor digitorum [blank_start]superficialis[blank_end] splits near the base of the [blank_start]proximal[blank_end] phalanx then inserts into the [blank_start]medial[blank_end] phalanx. This allows the flexor digitorum [blank_start]profundus[blank_end] tendon to pass between the splits of the [blank_start]flexor digitorum superficialis[blank_end] tendon and insert onto the [blank_start]distal[blank_end] phalanx.
