Pronator teres, flexor carpi radialis, palmaris longus, and flexor carpi ulnaris
what are the muscles of the superficial layer of the anterior compartment
ORIGIN humeral head: Common flexor tendon from the medial epicondyle of humerus, Ulnar head: coronoid process. INSERTION middle lateral surface of radius
What is the pronator teres
Flexor digitorum superficialis tendons, flexor digitorum profundus tendons, flexor pollicis longus, and median nerve are common structures of this.
What are the structures of the Carpal Tunnel?
ORIGIN: Proximal 2/3 of lateral supracondylar ridge of the humerus
INSERTION: styloid process of radius.
What is the brachioradialis?
My structures include extensor pollicis longus, radial artery, abductor pollicis longus, extensor pollicis brevis, and scaphoid.
What is the anatomical snuff box?
ORIGIN: lateral epicondyle, RCL, annular ligament, supinator crest of the ulna
INSERTION: anterior, lateral surface of proximal 1/3 of radius
What is the supinator?
The bulk of flexor digiti minimi brevis, opponens digiti minimi, abductor digiti minimi form this region of the hand.
What is the hypothenar eminence?
From the distal radius and runs obliquely and medially to split into three parts.1. radiotriquetral ligament 2. radiocapitate ligament 3. radioscaphoid ligament
what is the Palmar Radiocarpal ligament
ORIGIN: posterior surface of the ulna and radius & interosseous membrane
INSERTION: base of the 1st MC
What is the abductor pollicis longus?
abduction/adduction, flexion/extension, opposition
What are the movements of the thumb
Individually, we form the carpal bones.
What are Scaphoid, Lunate, Triquetrum, Pisiform, Hamate, Capitate, Trapizoid, & Trapezium?
I wrap around the head and neck of the radius providing stabilization to the proximal radius against the ulna during pronation and supination.
What is the annular ligamnet?
Supinator and extensor indices
what are the muscles of the deep layer of the posterior compartment
ORIGIN: anteromedial proximal 3/4 of the ulna and associated interosseus membrane
INSERTION: bases of the distal phalanges of the 2nd-5th digits
What is the what is the flexor digitorum profundus?
ORIGIN: medial, anterior surface of distal 1/4 of ulna
INSERTION: lateral, anterior portion of the distal 1/4 of the radius.
What is the pronator quadratus?
