1. Skeletal System Appendicular Skeleton Chapter 7

2. Right Pectoral (Shoulder) Girdle

3. Right Clavicle

4. Fractured Clavicle One of the most frequently fractured bones in the body. Fall on an outstretched arm. Automobile accidents with people wearing shoulder harnesses can result in fracture of the clavicle or damage to the median nerve from compression of the clavicle.

13. Pelvic Brim The pelvis is divided into superior and inferior portions by the pelvic brim. – Trace from the sacral promontory along the arcuate lines of the ilum and the iliopectineal lines of the pubis.

14. True and False Pelves False (greater) pelvis – the portion of the bony pelvis superior to the pelvic brim. – Abdominal cavity. True (lesser) pelvis – the portion of the bony pelvis inferior to the pelvic brim. – Pelvic cavity.

16. Comparison of Male and Female Pelves Female Light and thin Shallow Larger and more oval Small and faces anteriorly Oval Greater than 90° angle Male Heavy and Thick Deep Smaller, heart-shaped Large and faces laterally Round Less than 90° angle

17. Comparison of Male and Female Pelves Iliac crest – less curved Ilium – less vertical Greater sciatic notch – wide Coccyx – more movable and more curved anteriorly Sacrum – shorter, wider and more curved anteriorly Iliac crest – more curved Ilium – more vertical Greater sciatic notch – narrow Coccyx – less movable and less curved anteriorly Sacrum – longer, narrower and less curved anteriorly

18. Comparison of Male and Female Pelves Pelvic outlet – wider Ischial Tuberosity – shorter, farther apart, and more laterally projecting Pelvic outlet – narrower Ischial Tuberosity – longer, closer together, and more medially projecting

22. Patellofemoral Stress Syndrome A.K.A. “Runner’s knee.” During normal flexion and extension of the knee, the patella tracks (glides) up and down in the groove between the femoral condyles. The patella tracks laterally, which causes increased pressure on the joint. Pain occurs around or under the patella.
