The teeth of vertebrates represent the modified descendants of bony dermal (skin) plates that armoured ancestral fishes.
The most common esthetic signs of facial aging include visibility of bony landmarks, skin wrinkles, deep furrows, prominence of nasolabial folds, perioral vertical rhytids, ptosis of the oral commisures, and thinning of the lips.
Particular attention was paid to padding bony prominences and skin care in view of his poor skin condition.
It forms a buffer that dissipates pressure over bony prominences, preventing skin breakdown.
Initial diagnostic evaluations were unrevealing; however, hyperpigmented skin over bony prominences, skin nodules, and fleshy perianal masses suggested a diagnosis of systemic hyalinosis.
The dominant modern fishes, teleosts, are characterized by bony scales covered with skin.
She subsequently underwent placement of a graft of twin B's rib cage to bridge the bony chest defect and skin flap closure.
A few modern teleosts (some catfishes, sticklebacks, and others) have secondarily acquired bony plates in the skin.
One school of thought holds that ancient turtles had bony plates on their skin (similar to modern crocodiles) that eventually fused to form the shell.
They had to integrate functional components like a nose and lower eyelids, as well as different tissue types, including skin, muscles, bony structures, arteries, veins and nerves.
