BIOL 030 Lecture Notes - Lecture 18: Ulnar Artery, Teres Major Muscle, Olecranon Fossa
Document Summary
Foramen for nutrient artery hole for a blood vessel into bone. Radial groove where radial nerve travels along the bone. Radial fossa for radial head, on anterior side. Coranoid fossa for coranoid process of ulna, on anterior side. Capitulum a round protrusion, on anterior side. Trochlea a valley on the distal end. Medial epichondyle ulnar nerve passes behind it. Olecranon fossa on posterior side, accepts olecronon of ulna. Olecranon process what you feel at the elbow. Trochlear notch on the other side of the olecranon process (huh?) Coranoid process outside of the other end of the notch (huh?) Styloid process on distal end of ulna. Interosseous membrane connects radius and ulna and has openings at top and bottom. Styloid process on distal end, the ulna also has one. Lateral intermuscular septum separates anterior (flexor) from posterior (extensor) compartment. Brachial fascia a deep fascia which surrounds both compartments. Maintains integrity of the muscles; allows them to function as one;
