bruit

Back 10

[bro̅o̅′ē]
Etymology: Fr, noise
an abnormal blowing or swishing sound or murmur heard while auscultating a carotid artery, the aorta, an organ, or a gland, such as the liver or thyroid, and resulting from blood flowing through a narrow or partially occluded artery. The specific character of the bruit, its location, and the time of its occurrence in a cycle of other sounds are all of diagnostic importance. Bruits are usually of low frequency and are heard best with the bell of a stethoscope.

[¦kärd·ē·ō′vas·kyə·lər ‚sis·təm]

Front 12

cholesterol

Back 12

Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells. It's an important part of a healthy body because it's used to form cell membranes, some hormones and is needed for other functions. But a high level of cholesterol in the blood — hypercholesterolemia — is a major risk factor for coronary heart disease, which leads to heart attack.

Front 13

clavicle

Back 13

. either of the two bones connecting the shoulder blades with the upper part of the breastbone

Front 14

coccyx

Back 14

[′käk‚siks]
(anatomy)
The fused vestige of caudal vertebrae forming the last bone of the vertebral column in humans and certain other primates.

Front 15

collagen

Back 15

(kŏl`əjən), any of a group of proteins found in skin, ligaments, tendons, bone and cartilage, and other connective tissue connective tissue, supportive tissue widely distributed in the body, characterized by large amounts of intercellular substance and relatively few cells. The intercellular material, or matrix, is produced by the cells and gives the tissue its particular character.

The fibroblasts produce three types of fibers to form the ground substance: collagen, elatin, and the reticulum. Collagen consists of groups of white inelastic fibers with great tensile strength. These fibers include fine fibrils, which are composed of even finer filaments, visible only through the electron microscope. Collagen protein contains an unusually high percentage of the amino acids proline proline (prō`lēn), organic compound, one of the 20 amino acids commonly found in animal proteins.

X-ray diffraction studies provide evidence that the protein forms a wavy band, a coiled chain with periodic, i.e., repeating, arrangement of its amino acids. Cartilage is composed of fibrous collagen in an amorphous gel. The organic (nonmineral) content of bone is made up largely of collagen fibers with calcium salt crystals lying adjacent to each segment of the fiber; the fibers and salt crystals combined form a structure with compressional and tensile strength comparable to that of reinforced concrete. A group of diseases, often termed collagen, or connective tissue, diseases, involve a variety of alterations in the connective tissue fibers; rheumatoid arthritis, rheumatic fever, lupus, and scleroderma are included in this group. Some of these diseases may involve an autoimmune response, in which the immune mechanism injures or destroys the individual's own tissues (see immunity immunity, ability of an organism to resist disease by identifying and destroying foreign substances or organisms. Although all animals have some immune capabilities, little is known about nonmammalian immunity.

Collagen dissolved in boiling water becomes denatured to form gelatin gelatin or animal jelly, foodstuff obtained from connective tissue (found in hoofs, bones, tendons, ligaments, and cartilage) of vertebrate animals by the action of boiling water or dilute acid.
