Q

Chapter 11

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

A

right; Posterior

32
Q

Chapter 11

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

A

left; Anterior

33
Q

Chapter 11

Pectoral

A

flexibility most important; lightweight; insecure axaial and limb attachments

34
Q

Chapter 11

Pelvic

A

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

35
Q

Chapter 11

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

A

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

36
Q

Chapter 11

What is the difference between the true pelvis and the false pelvis?

A

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.

38
Q

Chapter 11

This is a (female/male) pelvis because?

A

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.

39
Q

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.

A

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.

40
Q

Chapter 11

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

A

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

41
Q

Chapter 11

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

A

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.

42
Q

Chapter 11

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

A

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.

43
Q

Chapter 11

What does fallen arches mean?

A

It mean flat feet or flat footed
