front 20 Why is the clavicle at risk to fracture when a person falls on his or her shoulder? | back 20 It is a slender, lightweight bone that withstands trauma poorly |
front 21 Why is it generally no problem for hte arm to clear the widest dimension of the thoracic cage? | back 21 The clavicle acts as a strut to hold the glenoid cavity of the scapula (therefore the arm) laterally away from the narrowest dimension of the rib cage. |
front 22 What is the total number of phalanges in the hand? | back 22 14 |
front 23 What is the total number of carpals in the wrist? | back 23 8 |
front 24 Name the carpals (medial to lateral) in the proximal row. Next name the carpals (medial to lateral) in the distal row. | back 24 pisiform, triagular (triquetrium), lunate, scaphoid; hamate, capitate, trapezoid, trapezium. |

front 27 lightweight | back 27 pectoral girdle |
front 28 nsecure axial and limb attachments | back 28 pectoral girdle |
front 29 secure axial and limb attachments | back 29 pelvic girdle |
front 30 weight-bearing most important | back 30 pelvic girdle |
front 31 What organs are protected, at least in part, by the pelvic girdle? | back 31 uterus (female), bladder, small intestine, rectum |
front 32 Why are the pelvic bones of a four-legged animal (like a cat or pig) much less massive than those of the human? | back 32 The pelvic girdle does not have to carry the entire weight of the trunk in the quadruped animal. |
front 33 Distinguish between the true pelvis and the false pelvis | back 33 The true pelvis is the region inferior to the pelvic brim, which is encircled by bone. The false pelvis is the area medial to the flaring iliac bones and lies superior to the pelvic brim. |
front 34 A person instinctively curls over his abdominal area in times of danger. Why? | back 34 Abdominal area organs recieve the least perotection from the skeletal system. |
front 35 For what anatomical reason do many women appear to be slightly knock-kneed? | back 35 The pelvis is broader and the acetabula and ilia are more laterally positioned. thus, the femur runs downward to the knee more obliquely than in the male. |
front 36 What does "fallen arches" mean? | back 36 A weakening of the tendons and ligaments supporting the arches of the foot. |
