Week 2 - Forearm Elbow And Humerus Flashcards
On the thumb side
Radius
On pinky side
Ulna
Radius/ ulna articulates with each other @
Distal /proximal radio-ulnar
Outer sides of both bones
styloid process
Where are styled processes located
Distal ends of both ulna and radius
Palpated on thumb side
Radial Styloid process
Located on medial aspect of the distal radius
U. notch
Head of U. Fits in u notch forming…..
Distal radio u. Joint
Head of u. Is located
Near the wrist@distal end of the U.
Head of radius located:
- Proximal end of radius near elbow joint
Radius is
-the shortest. And any one involved in wrist joints
UIna
Longer/ involved in formation of elbow joint
2 beak like processes of proximal u:
Olecranon /coronoid processes
Coronoid process opposite of radial notch (lateral ) is
Coronoid tubercle.
Large concave depression that articulates with distal humerus:
Trochiear notch
Small notch located @lateral aspect of proximal u:
Radial notch
Head of the radius articulates with the u @ radial notch forming
Proximal radio u joint
articular portion of humeral condyle divided into 2 parts
Trochlea and capitulum
Two shadow anterior depressions are
Coronoid fossa and radial fossa
Depression of distal humerus is
Olecranon fossa
Lateral epicondyle is
Smaller on lateral aspect above capitulum
Medial epicondyle is
Larger and more prominent located on medial edge
First and smallest
Trochlear sulcus
Smaller double lined ridges is
Capitulum
Larger/medial ridge
Trochlea
Captilum is known as the
Little head (found on lateral side)
