Document Summary

The olecranon is the point of the elbow; during extension of the elbow, the olecranon swings into the olecranon fossa on the posterior surface of the humerus to prevent overextension. Clavicle; it articulates with the manubrium of the sternum. Ten-year-old mark jumps off the back steps of his house, lands on his right heel, and breaks his foot. Mark has most likely fractured his calcaneus (heel bone) During dorsiflexion, as when "digging in the heels," all of the body weight rests on the calcaneus. During plantar flexion, as when "standing on tiptoe," the talus and calcaneus transfer the weight to the metatarsal bones and phalanges through more anterior tarsal bones. The broad, relatively flat portion of the clavicle that articulates with the scapula is the: sternal end, conoid tubercle, acromial end, costal tuberosity acromial end. The protuberance that you can feel on the lateral side of the ankle is the: lateral malleolus, lateral condyle, tibial tuberosity, lateral epicondyle.
