Answers to Quick Check Questions
1. Frontal bone, two parietal bones, two temporal bones, occipital bone, sphenoid bone, and
ethmoid bone.
2. Two maxillae: form part of the floor of the orbits, part of the roof of the mouth, and part of the
floor and sidewalls of the nose. Mandible: articulates with the temporal bone. Two nasal bones:
form the upper part of the bridge of the nose. Two zygomatic bones: form the outer margin of
the orbit. They articulate with the maxillary, temporal, frontal, and sphenoid bones. Two
lacrimal bones: help form the sidewall of the nose. They join the maxilla, frontal bone, and
ethmoid bone. Two palatine bones: join each other in the midline, forming the posterior part of
the hard palate. Two inferior conchae: form the upper and middle ledges of the nasal cavity.
Vomer: completes the septum posteriorly.
3. Hyoid.
4. Cervical (7), thoracic (12), and lumbar (5).
5. Ribs, vertebral column, and sternum. Each rib articulates with both the body and the transverse
process of the corresponding thoracic vertebra, and the tubercle of each rib articulates with the
vertebra’s transverse process. Anteriorly, each rib of the first seven pairs joins a costal cartilage
that attaches to the sternum.
6. A floating rib is one that does not attach even indirectly to the sternum.
7. Clavicle and scapula. The sternoclavicular joint between the sternum and clavicle.
8. Radius and ulna. The radius is lateral.
9. Hand bones: metacarpals. Wrist bones: carpals.
10. Ilium, ischium, and pubis.
11. Femur: thigh bone. Patella: kneecap, located in the tendon of the quadriceps femoris muscle as a
projection to the underlying knee joint. Tibia: larger of the lower leg bones. Fibula: smaller of
the two lower leg bones and more laterally and deeply placed. Tarsals: ankle bones. Metatarsals:
bones of the foot. Phalanges: toe bones.
12. Arches furnish more supporting strength per given amount of structural material.
13. Answers may include differences in general form, skull, and pelvis (cavity, sacrum, coccyx,
pubic arch, symphysis pubis, ischial spine, ischial tuberosity, anterior superior iliac spine, and
greater sciatic notch).
