ETYM Old Eng. brain, brein, AS. bragen, braegen; akin to LG. brägen, bregen, Dutch brein.
In higher animals, a mass of interconnected nerve cells forming the anterior part of the central nervous system, whose activities it coordinates and controls. In vertebrates, the brain is contained by the skull. At the base of the brainstem, the medulla oblongata contains centers for the control of respiration, heartbeat rate and strength, and blood pressure. Overlying this is the cerebellum, which is concerned with coordinating complex muscular processes such as maintaining posture and moving limbs.
The cerebral hemispheres (cerebrum) are paired outgrowths of the front end of the forebrain, in early vertebrates mainly concerned with the senses, but in higher vertebrates greatly developed and involved in the integration of all sensory input and motor output, and in thought, emotions, memory, and behavior.
In vertebrates, many of the nerve fibers from the two sides of the body cross over as they enter the brain, so that the left cerebral hemisphere is associated with the right side of the body and vice versa. In humans, a certain asymmetry develops in the two halves of the cerebrum. In right-handed people, the left hemisphere seems to play a greater role in controlling verbal and some mathematical skills, whereas the right hemisphere is more involved in spatial perception. In general, however, skills and abilities are not closely localized. In the brain, nerve impulses are passed across synapses by neurotransmitters, in the same way as in other parts of the nervous system.
In mammals the cerebrum is the largest part of the brain, carrying the cerebral cortex. This consists of a thick surface layer of cell bodies (gray matter), below which fiber tracts (white matter) connect various parts of the cortex to each other and to other points in the central nervous system. As cerebral complexity grows, the surface of the brain becomes convoluted into deep folds. In higher mammals, there are large unassigned areas of the brain that seem to be connected with intelligence, personality, and higher mental faculties. Language is controlled in two special regions usually in the left side of the brain: Broca’s area governs the ability to talk, and Wernicke’s area is responsible for the comprehension of spoken and written words. In 1990, scientists at Johns Hopkins University, Baltimore, succeeded in culturing human brain cells.

ETYM New Lat., from Greek; akin to kara head.
The part of the skull that encloses the brain; SYN. braincase, brainpan.
Skull, especially part enclosing brain.
The dome-shaped area of the vertebrate skull that protects the brain. It consists of eight bony plates fused together by sutures (immovable joints). Fossil remains of the human cranium have aided the development of theories concerning human evolution.
The cranium has been studied as a possible indicator of intelligence or even of personality. The Victorian argument that a large cranium implies a large brain, which in turn implies a more profound intelligence, has been rejected.
ETYM Old Eng. corone, coroun, crune, croun, Old Fren. corone, corune, French couronne, from Latin corona crown, wreath; akin to Greek korone anything curved, crown; cf. also Latin curvus curved. Related to Cornice, Corona, Coroner, Coronet.
Official headdress worn by a king or queen. The modern crown originated with the diadem, an embroidered fillet worn by Eastern rulers, for which a golden band was later substituted. A laurel crown was granted by the Greeks to a victor in the games, and by the Romans to a triumphant general. Crowns came into use among the Byzantine emperors and the European kings after the fall of the Western Empire.
Perhaps the oldest crown in Europe is the Iron Crown of Lombardy, made in 591. The crown of Charlemagne, preserved in Vienna, consists of eight gold plates.
1. The headware worn as a symbol of a monarchy.
2. (Archaic) An English coin worth 5 shillings.

skull / skəl /
Množina reči skull je skulls.
In vertebrates, the collection of flat and irregularly shaped bones (or cartilage) that enclose the brain and the organs of sight, hearing, and smell, and provide support for the jaws. In mammals, the skull consists of 22 bones joined by sutures. The floor of the skull is pierced by a large hole (foramen magnum) for the spinal cord and a number of smaller apertures through which other nerves and blood vessels pass.
The skull comprises the cranium (brain case) and the bones of the face, which include the upper jaw, enclosing the sinuses, and form the framework for the nose, eyes, and roof of the mouth cavity. The lower jaw is hinged to the middle of the skull at its lower edge. The opening to the middle ear is located near the jaw hinge. The plate at the back of the head is jointed at its lower edge with the upper section of the spine. Inside, the skull has various shallow cavities into which fit different parts of the brain.
The human skull has evolved from robust to gracile in the past 5. 5 million years; it exhibits neoteny (infantilism), whereby the youthful features of ancient human species are retained in the adult skulls of modern humans— probably to make room for the evolving and enlarging brain.
The bony skeleton of the head of vertebrates.
1. The highest or uppermost side of anything; SYN. top side, upper side, upside.
2. The upper part of anything
3. Something that covers a hole (especially a hole in the top of a container); SYN. cover.
