Question 31

# Chapter 11 The humerus is a (right/left) bone in (an anterior/a posterior) view.

Answer 31

right; Posterior

Question 32

# Chapter 11 The radius and ulna are (right/left) bones in (an anterior/a posterior) view.

Answer 32

left; Anterior

Question 33

# Chapter 11 Pectoral

Answer 33

flexibility most important; lightweight; insecure axaial and limb attachments

Question 34

# Chapter 11 Pelvic

Answer 34

massive; secure axail and limb attachments; weight-bearing most important

Question 35

# Chapter 11 What organs are protected, at least in part, by the pelvic girdle?

Answer 35

Uterus, bladdar, rectum, small intestine, and reproductive organs

Question 36

# Chapter 11 What is the difference between the true pelvis and the false pelvis?

Answer 36

The true pelvis is small bowl-like shape containing the unrinary bladder and sexual organs. The false pelvis is the area been the alla or wings of the pelvis. This is a much larger area and contains some of the abdominal organs like part of the small intestine and part of the colon.

Question 38

# Chapter 11 This is a (female/male) pelvis because?

Answer 38

Female; It is adapted for childbearing, defines birth canal, Farther apart then a males, the sacrum is wider, shorter and less curved then a males. The pelvic inlet (brim) is wider; oval from side to side.

Question 39

# Chapter 11 Deduce why the pelvis bones of a four-legged animal such as a cat or pig are less massive than those of the human.

Answer 39

The pelvic bones of a two-legged animal such as a human have to carry his whole weight, divided by two. A four-legged animal such as a pig divides its weight over four legs, so each leg and each pelvic bone has to bear only a fourth of the animal's weight. As the strain on the bones is a half than in the two-legged case, the bones can be less massive.

Question 40

# Chapter 11 A person instinctively curls over his abdominal area in times of danger. Why?

Answer 40

To prevent a smaller target and also to protect the internal organs and genitalia.

Question 41

# Chapter 11 For what anatomical reason do many women appear to be slightly knock-kneed?

Answer 41

Biologically, women have wider pelvises than men. The angle of their hips turn the legs slightly inward, making some to actually touch at the knees.

Question 42

# Chapter 11 How might this anatomical arrangement contribute to knee injuries in female athletes?

Answer 42

they can be more prone to knee related injuries, such as ACL tears due to high intensity straight knee landing or impact since the knee is already in a weak position.
