Head

In anatomy, the head of an animal is the rostral part (from anatomical position) that usually comprises the brain, eyes, ears, nose and mouth (all of which aid in various sensory functions, such as sight, hearing, smell, and taste). Some very simple animals may not have a head, but many bilaterally symmetric forms do. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nerve tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region, which collectively form the head.

Famous quotes containing the word head:

“Sebastian: Angel was like cognac, all fire in a glass. But you, you are like champagne. Sparkling, tantalizing, you make a man’s head spin.
Holly: Pheww ... you’ve got a terrific line.”
—Fredric M. Frank (1911–1977)

“We may not pay Satan reverence, for that would be indiscreet, but we can at least respect his talents. A person who has for untold centuries maintained the imposing position of spiritual head of four-fifths of the human race, and political head of the whole of it, must be granted the possession of executive abilities of the loftiest order.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)

“Dead drunk
is the term I think of,
insensible,
neither cool nor warm,
without a head or a foot.
To be drunk is to be intimate with a fool.”
—Anne Sexton (1928–1974)
