100
This nerve innervates the triceps brachii

What is radial?

100

This is the bony landmark on the proximal ulna that protrudes laterally

What is the coronoid process?
100

These structures on the palmar and dorsal side of the wrist prevent bowstringing of tendons

What are retinaculum?

100

This muscle is the most effective in flexing the elbow when the forearm is in neutral

What is brachioradialis?

100

During pronation and supination at the distal radioulnar joint, the surfaces roll and glide in this direction

What is the same?

200

This muscle originates from the anterior surface of the radius and interosseous membrane to insert on the distal phalanx of the thumb

What is flexor pollicis longus?

200

This arch is formed by the base of the metacarpals and the carpal bones

What is the proximal transverse arch?

200

The medial collateral ligament of the elbow limits this motion

What is valgus?

200

A patient diagnosed with Tennis Elbow is experiencing this (the proper term for this ailment) 

What is lateral epicondylitis?

200

The MCP joints of digits 2-5 will roll and glide in this direction during flexion/extension

What is the same?

300

The lumbricals insert on this location 

What is the extensor expansion?

300

When the hand is fisted, this is the term for the heads of the metacarpals and phalanges

What is a knuckle?

300

This structure lies between the radius and the ulna to provide stability, transmit forces and attach muscles

What is the interosseous membrane?

300

This is a generic diagnosis describing common shoulder pain in many patients especially with overhead movements

What is impingement syndrome?

300

During elbow flexion and extension, this shape is moving at the joint surfaces

What is concave?

400

This muscle is innervated by the radial nerve and works to extend the MCP, PIP, and DIP of the little finger

What is the extensor digiti minimi?

400

This small protuberance on the anterior forearm bone is the attachment site for the biceps brachii

What is the radial tuberosity?

400

This ligament near the elbow surrounds the radial head and inserts on two locations of the radial notch of the ulna

What is annular ligament?

400

This muscle is very effective during pushing with the forearm in pronation despite the muscle not being affected by forearm positioning

What is triceps?

400

This arthrokinematic motion occurs at the humeroradial joint during pronation/supination

What is spin?

500

These two muscles insert on the base of the 5th metacarpals

What are the FCU and ECU?

500

This convex surfaces of the humerus articulates with the ulna whereas this one articulates with radius

What are the trochlea and capitulum, respectively?
500

This soft tissue structure is the attachment for the palmaris longus and it covers the tendons of extrinsic muscles

What is the palmar aponeurosis?

500

This is the deformity in the hand characterized by MCP extension, PIP flexion, and DIP extension

What is boutonniere's deformity?

500

With opposition of the CMC joint, the roll and glide occur this direction

What is BOTH, same and opposite? (roll anterior and medial; glide posterior and medial)
