Feet/Hooves
The hoof of the horse encases the second and third phalanx of the lower limbs, analogous to the fingertip or toe tip of a human. In essence, a horse travels on its "tiptoes." The hoof wall is a much larger, thicker and stronger version of the human fingernail or toenail, made up of similar materials, primarily keratin, a very strong protein molecule. The horse's hoof contains a high proportion of sulfur-containing amino acids which contribute to its resilience and toughness. Vascular fold-like structures called laminae suspend the distal phalanx from the hoof wall.

Famous quotes containing the words feet and/or hooves:
“This world has many rings, like Saturn, and we live now on the outmost of them all. None can say deliberately that he inhabits the same sphere, or is contemporary, with the flower which his hands have plucked, and though his feet may seem to crush it, inconceivable spaces and ages separate them, and perchance there is no danger that he will hurt it.”
—Henry David Thoreau (1817–1862)
“Your hooves have stamped at the black margin of the wood,
Even where horrible green parrots call and swing.
My works are all stamped down into the sultry mud.”
—William Butler Yeats (1865–1939)
