Answer
  • True
  • False

Question 3

Question
[blank_start]Compact[blank_end] bone is needed for strength and weight bearing. [blank_start]Cancellous[blank_end] bone is for shock absorption.
Answer
  • Compact
  • Cancellous

Question 4

Question
Compact and cancellous bone are made of the same materials.
Answer
  • True
  • False

Question 5

Question
Which of the following is not a class of bone shape?

  • Long bones
  • Short bones
  • Sesamoid bones

Answer
  • True
  • False

Question 7

Question
Select the correct summaries about bone's gross structure.
Answer
  • Flat bones are curved, have a thin layer of cancellous bone within two thin layers of compact bone, and provide protection or surface for muscle attachment.
  • Irregular bones can be differentiated from flat bones generally by observing they have a hole within them.
  • Long bones have a diaphysis, and wider extremities at the ends called the epiphyses. They function as levers.
  • Short bones are equal in length and width, and are mostly compact bone.
  • Sesamoid bones vary from person to person.

Answer
  • skull, thoracic cage, vertebral column

Answer
  • 7
  • 12
  • 5

Question 12

Question
The thoracic cage comprises of the [blank_start]sternum[blank_end], costal [blank_start]cartilage[blank_end], and 12 sets of [blank_start]ribs[blank_end] on each side (with [blank_start]7[blank_end] being true ribs.)
Answer
  • sternum
  • cartilage
  • ribs
  • 7

Question 13

Question
The pectoral girdle comprises of the [blank_start]clavicle and scapula[blank_end], which allow a large ROM. It is [blank_start]less[blank_end] stable than the pelvic girdle, which is comprised of the [blank_start]two hip bones and the sacrum[blank_end](which is axial).
Answer
  • clavicle and scapula
  • less
  • more
  • two hip bones and the sacrum

  • The humerus articulates with the fibula.
  • The ulna is the medial bone of the forearm.
