Name the part of the axial skeleton that fits each clue.
- The eight bones that form the hard covering of the brain.
- The fourteen bones that form the front of the skull.
- The single U shaped bone at the base of the buccal cavity.
- The malleus, the incus and the stapes.
- The two knobs at the base of the skull that join the first vertebra.
Need a reminder? The key ideaShow
The skeleton has bones. The axial skeleton has bones: the skull ( cranial and facial bones), the hyoid (), the ear ossicles (), the vertebral column ( units: cervical, thoracic, lumbar, sacral, coccygeal), the sternum () and pairs of ribs (). Ribs: pairs true, pairs false, pairs floating.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) The cranial bones.
Step 2. (b) The facial bones.
Step 3. (c) The hyoid.
Step 4. (d) The ear ossicles, three in each middle ear.
Step 5. (e) The occipital condyles. The first vertebra, the atlas, articulates with them.
Answer: (a) cranial bones; (b) facial bones; (c) hyoid; (d) ear ossicles; (e) occipital condyles.
Check. The cranial and facial bones together make bones.
