Chapter 5 Worksheet - Upper Extremity

Vocabulary flashcards covering the anatomical landmarks and features of the upper extremity humerus from Chapter 5 Worksheet.

Greater tubercle

Rounded process located on the lateral surface of the bone just below the anatomic neck

Intertubercular groove

Deep depression that separates the lesser and greater tubercles

Condyle

Expanded distal articular end

Surgical neck

Constricted area of the body just below the tubercles and is a commoly fractured region

Trochlea

Smooth elevation on the distal medial aspect

Radial fossa

Shallow depression on the distal anterior surface that recieves the radial head when the elbow is flexed

Coronoid fossa

Shallow depression on the distal anterior surface that recieves the coronoid process

Olecranon fossa

Deep depression on the posterior surface

Anotomical neck

Narrow constricted portion just inferior to the head and lying in the same oblique plane

Lateral epicondyle

Easily palpable surface just superior to the humeral condyle on the lateral surface

Body

Capitulum

Smooth elevation on the distal end, articulates with the radial head

Medial epicondyle

Easily palpable surface just superior to the humeral condyle on the medial surface

Head
