Exposed Bone
Bone penetrating the skin and being exposed to the outside can be both a natural process in some animals, and due to injury:
- A deer's antlers are composed of bone.
- Instead of teeth, the extinct predatory fish Dunkleosteus had sharp edges of hard exposed bone along its jaws.
- A compound fracture occurs when the edges of a broken bone puncture the skin.
- Though not strictly speaking exposed, a bird's beak is primarily bone covered in a layer of keratin over a vascular layer containing blood vessels and nerve endings.

Famous quotes containing the words bone and/or exposed:
“Here lies the body of William Jones
Who all his life collected bones,
Till Death, that grim and boney spectre,
That universal bone collector,
Boned old Jones, so neat and tidy,
And here he lies, all bona fide.”
—Anonymous. Epitaph on William Jones, from Eleanor Broughtons Varia (1925)
“Platowho may have understood better what forms the mind of man than do some of our contemporaries who want their children exposed only to real people and everyday eventsknew what intellectual experience made for true humanity. He suggested that the future citizens of his ideal republic begin their literary education with the telling of myths, rather than with mere facts or so-called rational teachings.”
—Bruno Bettelheim (20th century)
