|
Humerus |
Arm bone/brachium, articulates distally with the radius and ulna at elbow, humeroulnar and humeroradial joints |
|
|
Olecranon Fossa |
deep cavity for articulation with the olecranon process of the ulna |
|
|
Medial Condyle |
Trochlea, articulates with the base of the ulna |
|
|
Lateral Condyle |
Capitulum, articulates with the head of the radius |
|
|
Medial Epicondyle |
above the condyle where forearm flexors originate off of and where golfer's elbow occurs |
|
|
Lateral Epicondyle |
above the condyle where forearm extensors originate off of and where tennis elbow occurs |
|
|
Medial and Lateral Supracondylar Ridges |
lie above the epicondyles are for muscular attacments |
|
|
Ulna |
Located on the medial forearm, has a palpable ridge from the elbow (olecranon process) to the wrist (ulnar styloid process), the head lies distally while the base lies proximally |
|
|
Radius |
Located on the lateral forearm, not as superficial at the ulna except at distal end, head lies proximally while the base lies distally, radial styloid process is at lateral wrist, pivots around the ulna at the radioulnar joints |
|
|
Coronoid Process |
proximal anterior ulna |
|
|
Lister's Tubercle |
posterior base of radius |
|
|
Carpals |
wrist bones, 8 bones arranged in 2 rows lie distal to the flexor crease of the wrist, proximal to distal: scaphoid, lunate, triquetrium, pisiform, trapezium, trapezoid, capitate, hamate |
|
|
Radiocarpal Joint |
distal radius and proximal row of carpals form this |
|
|
Metacarpal Joints |
5 long bones, superficial in the dorsum of the hand, prox=base, mid=shaft, distal=head, thenar eminence thumb muscles, hypothenar eminence muscles proximal to pinky |
|
|
Phalanges |
1-4 on each hand, thumbs had 2 digits have 3, have a base, shaft, and head |
|
|
Distal tuft |
roughened surface on the posterior head of each phalanx that supports the nail bed and nail |
|
|
Metacarpophalangeal Joints |
knuckles, lie between distal metas and pahlanges, joints between phalanges are interpahlangeal joints, PIPs and DIPs |
|
|
Radial Collateral Ligament |
cord like CT band from the lateral epicondyle to the annular ligament and olecranon process |
|
|
Annular Ligament |
wraps around the radial head and neck, stabilizes the proximal radius against the ulna during pronation and supination |
|
|
Ulnar Collateral Ligament |
medial, triangle shaped, from medial epicondyle to the coronoid process and olecranon process |
|
|
Ulnar Nerve |
passes between the medial epicondyle and the olecranon process, responsible for the funny bone sensation down the arm |
|
|
Olecranon Bursea |
just distal to triceps brachii tendon, pads space between olecranon process and elbow skin |
|
|
Flexor Retinaculum |
transverse thickening of fascia in the anterior wrist, just distal to the flexor crease, stabilizes the wrist flexors with the carpal bones, helps form carpal tunnel |
|
|
Palmar Aponeurosis |
continuation of the antebrachial fascia located in the palm of the hang |
|
|
Extensor Retinculum |
transverse thickening of fascia located in the posterior wrist, just distal to the extensor crease, stabilizes wrist and thumb extensors |
|
|
Radial and Ulnar Arteries |
formed by the bifurcation of the brachial A at the elbow, radial A is the most commonly used to take a pulse, located between flexor carpi radialis and the distal radial shaft, ulnar A may be palpable proximal to the pisiform and lateral to the tendon of flexor carpi ulnaris |
|
|
Anatomical Snuff Box |
Depression locate at the lateral wrist, formed by tendons of extensor pollicis longus, extensor pollicis brevis, and abductor pollicis |
|
|
Carpal Tunnel |
located in anterior wrist, median nerve and wrist flexors pass through |
|
|
Tunnel of Guyon |
located in anterior wrist, formed by the pisiform and hook of the hamate, covered by pisohamate ligament, ulnar nerve and artery run through it |
