Term | Definition |
---|---|
Clavicle | Commonly called the collarbone. The sternal end is medial, and the acromial end is lateral. |
Scapula | Commomly called the shoulder blade. This triangular shaped bone articulates the clavicel and the humerus |
Humerus | The arm bone. Articulates with the scapula, the radius, and the ulna. |
Ulna | The medial forearm bone. Articulates with the humerus, radius, and carpals. |
Radius | The lateral forearm bone. Articulates with the humerus, ulna, and carpals. |
Carpals | Wrist bones. 4 proximal and 4 distal. Scaphoid— Lunate— Triquetrum— Pisiform— Trapezium— Trapezoid— Capitate— Hamate |
Metacarpals | Numbered 1-5 from lateral to medial and located in the hand. Articulate with the carpals and phalanges. |
Phalanges | Also called digits. Articulate with adjacent phlanges and metacarpasl. Each finger has 3, the thumb only 2. |
Sternoclavicular | the joint between the sternum and the clavicle |
Acromioclavicular | The joint between the acromion process of the scapula and the clavicle |
Shoulder Girdle | Includes the clavicle and scapula |
Glenohumeral joint | the shoulder joint made between the scapula and humerous |
Humeroradial | Part of the elbow joint where the humerus and radius articulate |
Humeroulnar | Part of the elbow joint where the humerus and the ulna articulate |
Radioulnar | The joint between the proximal and distal radius and ulna |
Transverse Carpal Ligament | The retaining band on the anterior side of the wrist that creates a tunnel along with the carpal bones. |
Carpal tunnel | compartment created by the carpal bones and the transverse carpal ligament where tendons and nerves pass through the wrist |
Radiocarpal joint | wrist joint, where the radius and carpals articulate |
Carpometacarpal | the joint where the carpals and metacarpals articulate |
Metocarpalphalangeal | the knuckle joints, articualtion between the metocarpals and the phalanges |
Interphalangeal | The joint between the phalanges |
PIP | The proximal interphalangeal joints |
DIP | The distal interphalangeal joints |
Interosseous | connective tissue membrane in the space between the radius and ulna. Also seen between the tibia and fibula. |
Axillary | Armpit |
Brachial | arm |
cubital | elbow |
Antecubital | front of elbow |
Antebrachial | forearm |
