Appendicular skeleton-Upper extremity Flashcards
Humerus
long bone of the upper arm
Head
proximal round portion which articulates with the glenoid cavity of the scapula
Anatomical Neck
Tapering of the humerus immediately inferior to the head
Greater Tubercle
A process laterall to the humeral head and inferior to the anatomical neck
Lesser Tubercle
process anterior to the greater tubercle of the humerus
Intertubercular groove
groove between the greater and lesser tubercles of the humerus
Surgical neck
Tapering region of the humeral shaft inferior to the anatomical neck
Deltoid tuberosity
elevation on lateral side of the humeral shaft for muscle attachment
Medial supracondylar ridge
smoothe prominence located proximal to medial epicondyle for muscle attachment
Lateral supracondylar ridge
smoothe prominence located proximal to lateral epicondyle for muscle attachment
Capitulum
lateral condyle on the distal end of the humerus which articulates with the head of the radius
Trochlea
medial condyle on the distal end of the humerus which articulates with the trochlear notch
Lateral epicondyle
located on the distal end of the humerus superior to the capitulum
Medial epicondyle
located on the distal end of the humerus superior to the trochlea
Coronoid fossa
located on the anterior side of the distal end of the humerus superior to the trochlea and articulates with the coronoid process of the ulna
