Osseous Structures
This bony landmark is the attachment site for the triceps brachii muscle
What is the olecranon process
This structure provides stability between the radius and the ulna at both the proximal and distal ends
What is the interosseous membrane
The flexor digitorum superficialis is innervated by this nerve
What is the ulnar nerve
This nerve is commonly entrapped at the cubital tunnel
What is the ulnar nerve
This bony landmark articulates with the head of the radius
What is the capitellum
These two ligaments form the carpal tunnel
What is the deep transverse metacarpal ligament and the transverse intercarpal ligaments
The ligaments of the extensor digitorum and the extensor indicis pass through which extensor compartment?
This nerve is commonly entrapped at the carpal tunnel
What is the median nerve
This bone is larger distally than it is proximally
What is the radius
This structure is composed of fibrocartilage and increases the congruence of the MCP joints
What is the volar/palmar plates
This landmark is the insertion of the extensor carpi radialis longus
What is the base of the 2nd metacarpal
This nerve is commonly entrapped at the arcade of frohse
What is the radial nerve
Which carpal bone articulates with the 4th and 5th metacarpals?
What is the hamate
This ligament is part of the ulnar collateral bundle, attaches ulna-to-ulna and provides little restraint to valgus forces
What is the transverse ligament
This is the only muscle of the thumb that is NOT innervated by the median nerve
What is the adductor pollicis
What are the nerve roots for the median nerve?
What is C5-T1
How many degrees is the 1st metacarpal rotated and in what direction?
What is 90 degrees and medially
The function of this structure is to act as a spacer between the head of the ulna and the triquetrum and the lunate
What is the triangular fibrocartilage complex (TFCC)
What is the origin of the 1st lumbrical?
What is the tendon of flexor digitorum profundus (radial side)
Which branch of the radial nerve is sensory only?
What is the superficial interosseous nerve
