Which of the following forearm muscles is not involved in flexion of the wrist?	Pronator Teres
Which of the following ligaments does not cross the elbow joint?	Ulnar collateral (transverse band)
Which of the following ligaments surrounds the head of the radius and helps to maintain stability of the proximal radioulnar joint?	Annular
A movement unique to the thumb that allows for grasping is known as	Opposition
A muscle found just proximal to the wrist that is involved in the action that "turns down" the forearm and the palm of the hand is the	pronator quadratus
Bands of tissue forming bridges over the carpal bones of the wrist under which the flexor and extensor tendons from the forearm run to the hand are known as the:	Retinacula
T/F: Beneath the space known as the anatomical snuffbox lies the lunate carpal bone.	False
Extension of the thumb is the function of the	Extensor pollicis longus
T/F: Extension of the wrist primarily occurs at the radiocarpal joints.	False
T/F: Flexion of the wrist occurs primarily at the radiocarpal joints.	True
From the anatomical position, thumb abduction and adduction occur in the sagittal plane, while thumb flexion and extension take place in the	Frontal Plane
In addition to the adductor pollicis and flexor pollicis brevis, which of the following muscles assists the thumb in gripping?	Opponens pollicis
Including the thumb, how many interphalangeal joints are in one anatomically normal hand?	9
The articulation between the wrist and the forearm occurs between the radius and the	Carpals
T/F: The bands of tissue at the wrist that keep the flexor muscles and the extensor muscles from rising up under tension are known as the dorsal and volar aponeuroses.	False
The distal row of carpal bones articulates with the	Metacarpals
The dorsal interossei muscles perform which of the following metacarpophalangeal joint actions?	Abduction
T/F: The extensor indicis extends the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints of the middle finger.	False
