column a
condyle
b. crest
c. facet
d. foramen
e. fossa
f. line
g. tuberosity
column b

1. small, nearly flat articular surface
2. shallow basin
3. rounded process
4. opening or hole
5. knoblike rough elevation
6. ridgelike projection
7. slightly raised ridge

Explanation:

1. The two main divisions of the human skeleton are the axial (which includes the skull, vertebral column, and thoracic cage) and appendicular (which includes the limbs and girdles).
2. Sutural bones are small, extra bones that can form between the flat bones of the skull.
3. The cranium and facial bones together make up the skull.
4. The hyoid bone supports the tongue and is unique as it does not articulate with any other bone.
5. The coccyx at the inferior end of the sacrum is composed of four (sometimes three - five) fused vertebrae.
6. Most ribs are attached anteriorly to the sternum.
7. The thoracic cage is composed of 12 pairs of ribs.
8. The scapulae and clavicles form the pectoral girdle.
9. The humerus, radius, and ulna articulate to form the elbow joint.
10. The wrist is made up of eight carpal bones.
11. The hip bones are attached posteriorly to the sacrum.
12. The patella covers the anterior surface of the knee.
13. The bones that articulate with the distal ends of the tibia and fibula are the tarsal bones.
14. All finger and toe bones are called phalanges.

For the matching part:

• Condyle is a rounded process, so it matches with 3.
• Crest is a ridgelike projection, so it matches with 6.
• Facet is a small, nearly flat articular surface, so it matches with 1.
• Foramen is an opening or hole, so it matches with 4.
• Fossa is a shallow basin, so it matches with 2.
• Line is a slightly raised ridge, so it matches with 7.
• Tuberosity is a knoblike rough elevation, so it matches with 5.

1. axial
2. sutural
3. skull
