Document Summary
Describe the bony and surface landmarks of the arm and forearm. a. humerus: medial epicondyle and medial supracondylar ridge - 7) superficial flexor mm. of forearm attach here. Lateral epicondyle and lateral supracondylar ridge - extensor mm. of forearm attach here. Capitulum (little head) articulates with the head of the (thus, it is lateral) Trochlea (pulley) articulates with the ulna (thus, it is. Coronoid fossa receives coronoid process of ulna. Olecranon fossa - olecranon p. of ulna fits into this when elbow is extended. Styloid process - radial collateral ligament of wrist attaches here. Trochlear notch - articulates with trochlea of humerus. Coronoid p. - is located at the anterior point of the surface that articulates with the medial part of the trochlea. Styloid p. - ulnar collateral ligament of wrist attaches here. Note that the entire length of the ulna is subcutaneous and easily palpable along its posterior border, where it separates flexors and extensors.
