Head

A head is the part of an organism, which usually comprises the eyes, ears, nose and mouth, each 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, nervous 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; these collectively form the head.

Human head

The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). The skull can also be described as being composed of the cranium, which encloses the cranial cavity, and the facial skeleton (includes the mandible). There are eight bones in the cranium and fourteen in the facial skeleton.

Anatomy 2

Anatomy 2 (German: Anatomie 2) is a 2003 German thriller film written and directed by Stefan Ruzowitzky. It's the sequel to the 2000 film Anatomy, that starred Franka Potente. The story moves to Berlin for this film.

Plot

The Heidelberg chapter of the Anti-Hippocratic Society for unrestricted medical research has been shut down, but at a prestigious Berlin hospital the society still thrives. The young neurosurgeon Jo from Duisburg gets caught up in a research group led by doctor Mueller LaRousse, who urges his students to test their progress on themselves. Jo participates in the trials to eventually help his brother, who has Muscular Dystrophy. When Jo and some of his fellow students show some reluctance, Mueller LaRousse uses alternative means to punish them before they can give up the society to Paula Henning, who is now investigating the society for the police.

Head (watercraft)

The head (or heads) is a ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the ship.

Design

In sailing ships, the toilet was placed in the bow for two reasons. Firstly, since most vessels of the era could not sail directly into the wind, the winds came mostly across the rear of the ship, placing the head essentially downwind. Secondly, if placed somewhat above the water line, vents or slots cut near the floor level would allow normal wave action to wash out the facility. Only the captain had a private toilet near his quarters, at the stern of the ship in the quarter gallery.

In many modern boats, the heads look similar to seated flush toilets but use a system of valves and pumps that brings sea water into the toilet and pumps the waste out through the hull in place of the more normal cistern and plumbing trap to a drain. In small boats the pump is often hand operated. The cleaning mechanism is easily blocked if too much toilet paper or other fibrous material is put down the pan.

Head (Julian Cope song)

Pseudanthium

A pseudanthium (Greek for "false flower") or flower head is a special type of inflorescence, in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The individual flowers of a pseudanthium commonly are called florets. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower).

Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorphic and the corolla has one large lobe (the so-called "petals" of a daisy are individual ray flowers, for example). Either ray or disk flowers may be absent in some plants: Senecio vulgaris lacks ray flowers and Taraxacum officinale lacks disk flowers. The pseudanthium has a whorl of bracts below the flowers, forming an involucre.
