IMED1001 Lecture Notes - Lecture 4: Patellar Ligament, Sesamoid Bone, Hip
Document Summary
Define the 2 subdivisions of the skeleton (axial and appendicular) Define several terms that denote surface features of bones. Recognise how joint structure contributes to movement characteristics. Identify the long bones of the human body. Anterior view of right pectoral girdle posterior view of the right pectoral girdle. Humeral head is much larger than articular surface of scapula. Joint capsule and ligaments are weak so joint is reinforced by muscles (rotator cuff) What movement occurs here: circumduction flexion, extension, abduction, adduction. Hence more vulnerable to an anterior dislocation. What movement occurs here: flexion, extension, pronation, supination, rotation of the radial head, flexion at more than 180 degrees and extension. What type of synovial joint is it: simple hinge joint. Wrist= radiocarpal joint (where the radius articulates with the scaphoid and the lunate carpal bones: extend, flexion and adduction and abduction.
