What are two reasons why the clavicle is so susceptible to fractures? 1. it is rather thin, yet sometimes is subjected to heavy forces --eg., break fall by reaching out with your arms (forces are transferred to clavicle) 2. Anterior border of clavicle is not protected by muscle or fat what about the clavicle lessens the danger to the subclavian artery when the clavicle does fracture? because of its curved shape, when it fractures, it usually fractures outward. **extremely advantageous because lessens danger to the huge subclavian artery which runs just below the clavicle. What is the function of the coracoid process? what bone is it found on? attachment point for muscles and ligaments that stabilize the shoulder what are the two functions of the pectoral girdle? 1. Attaches arms to axial skeleton. 2. Attachment site for many muscles that move the arms. describe in detail why the pectoral girdle allows a wider range of movements than the pelvic girdle? compared to the pelvic girdle, the pectoral girdle is very light and allows a wide range of arm/shoulder movements bc of small, flexivble joints between clavicle and manubrium. - and between clavicle and scapula. ***very different from robust sacroiliac joint. (SI joint). What is a disadvantage od the greater mobility of the pectoral girdle? dislocations of shoulders. head of humerus comes out of glenoid cavity, stretches ligaments and tendons holding it in place. more likes to happen after initial dislocation. what bones make up the pelvic girdle? 2 Os Coax (ilium, pubis, ischium) joined anteriorly by the pubic symphysis. What is the joint called that joins the left and right pubic bones? pubic symphysis what three bones make up each os coxa? Illium, ischium, pubis where is the acetabulum found? what is its function? in the pelvis. where the head of the femur articulates. but femur is in the deep socket and tightly bound by ligaments. what are the three functions of the pelvic girdle? 1. Attaches legs to axial skeleton. 2. Transmits the weight of the body to the legs via "hip joint" (acetabumlum-femur). 3. Supports/protects the lower viscera. (Bladder, reproductive/digestive organs, fetus.) What are a few anatomical differences between the male and female pelvic girlies? 1. pubic arch is wider in females 2. coccyx (tailbone) is less sharply angled, and is more flexible in females. 3. acetabulae are farther apart in females Describe how a baby moves through the pelvis during birth? Baby twists head and then shoulders as it passes through the birth canal
