Tissues Of The Body: From 1 Different Sources
The simple elements from which the various parts and organs are found to be built. All the body originates from the union of a pair of CELLS, but as growth proceeds the new cells produced from these form tissues of varying character and complexity. It is customary to divide the tissues into ?ve groups:
Epithelial tissues, including the cells covering the skin, those lining the alimentary canal, those forming the secretions of internal organs. (See EPITHELIUM.)
Connective tissues, including ?brous tissue, fat, bone, cartilage. (See under these headings.)
Muscular tissues (see MUSCLE).
Nervous tissues (see NERVE).
Wandering corpuscles of the BLOOD and LYMPH. Many of the organs are formed of a single
one of these tissues, or of one with a very slight admixture of another, such as cartilage, or white ?brous tissue. Other parts of the body that are widely distributed are very simple in structure and consist of two or more simple tissues in varying proportion. Such are blood vessels (see ARTERIES; VEINS), lymphatic vessels (see LYMPHATICS), lymphatic glands (see GLAND), SEROUS MEMBRANES, synovial membranes (see JOINTS), mucous membranes (see MUCOUS MEMBRANE), secreting glands (see GLAND; SALIVARY GLANDS; THYROID GLAND) and SKIN.
The structure of the more complex organs of the body is dealt with under the heading of each organ.
Body Mass Index (BMI) provides objective criteria of size to enable an estimation to be made of an individual’s level or risk of morbidity and mortality. The BMI, which is derived from the extensive data held by life-insurance companies, is calculated by dividing a person’s weight by the square of his or her height (kilograms/ metres2). Acceptable BMIs range from 20 to 25 and any ?gure above 30 characterises obesity. The Index may be used (with some modi?cation) to assess children and adolescents. (See OBESITY.)... body mass index
That part of the EYE that connects the iris and the choroid. The ciliary ring is next to the choroid; the ciliary processes comprise many ridges behind the iris, to which the lens’s suspensory ligament is attached; and the ciliary muscle contracts to change the curvature of the lens and so adjust the accommodation of the eye.... ciliary body
A small reddish-brown structure measuring 5–7 × 2·5–4 millimetres, situated one on each side of the neck, where the carotid artery divides into the internal and external carotid arteries. Its main function is in controlling breathing so that an adequate supply of oxygen is maintained to the tissues of the body. Oxygen levels are controlled by a re?ex operating between the carotid body and the respiratory centre in the brain.... carotid body

the temperature of the body, as measured by a thermometer. Body temperature is accurately controlled by a small area at the base of the brain (the *hypothalamus); in normal individuals it is maintained at about 37°C (98.4°F). Heat production by the body arises as the result of vital activities (e.g. respiration, heartbeat, circulation, secretion) and from the muscular effort of exercise and shivering. A rise in body temperature occurs in fever.... body temperature
