| ballistocardiogram | A record of the body's recoil caused by cardiac contraction, the ejection of blood into the aorta, and ventricular filling forces; has been used as a basis for calculating the cardiac output in man, but its lack of accuracy and reproducibility has caused it to be discarded. Origin: G. Ballo, to throw, + kardia, heart, + gramma, something written (05 Mar 2000) |
| ballistocardiograph | Instrument for taking a ballistocardiogram, consisting either of a moving table suspended from the ceiling, or of an apparatus that rests upon the patient's body, usually on the shins, together with a graphic recording system. (05 Mar 2000) |
| ballistocardiography | Technique of graphic representation of the movements of the body imparted by the ballistic forces (recoil and impact) associated with cardiac contraction and ejection of blood and with the deceleration of blood flow through the large blood vessels. These movements, quantitatively very minute, are translated by a pickup device (transducer) into an electrical potential which is suitably amplified and recorded on a conventional electrocardiograph or other recording machine.

| ballistophobia | <psychology> Morbid fear of a projectile or missile. Origin: G. Ballista, catapult, fr. G. Ballistes fr. Ballo, + phobos, fear (05 Mar 2000) |
| balloon | 1. A bag made of silk or other light material, and filled with hydrogen gas or heated air, so as to rise and float in the atmosphere; especially, one with a car attached for aerial navigation. 2. A ball or globe on the top of a pillar, church, etc, as at St. Paul's, in London. 3. <chemistry> A round vessel, usually with a short neck, to hold or receive whatever is distilled; a glass vessel of a spherical form. 4. <chemistry> A bomb or shell. 5. A game played with a large infated ball. 6. The outline inclosing words represented as coming from the mouth of a pictured figure. Air balloon, a balloon for aerial navigation. Balloon frame, a house frame constructed altogether of small timber. Balloon net, a variety of woven lace in which the weft threads are twisted in a peculiar manner around the warp. Origin: F. Ballon, aug. Of balle ball: cf. It. Ballone. See 1st Ball, and cf. Pallone. Source: Websters Dictionary (01 Mar 1998) |
| balloon angioplasty | <cardiology> Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, angioplasty, transluminal, percutaneous coronary is available. Coronary angioplasty is accomplished using a balloon-tipped catheter inserted through an artery in the groin or arm to enlarge a narrowing in a coronary artery. Coronary artery disease occurs when cholesterol plaque builds up (atherosclerosis) in the walls of the arteries to the heart. Angioplasty is successful in opening coronary arteries in 90% of patients. 40% of patients with successful coronary angioplasty will develop recurrent narrowing at the site of balloon inflation.

| balloon catheter | A catheter used in arterial embolectomy or to float into the pulmonary artery. (05 Mar 2000) |
| balloon cell | An unusually large degenerated cell with pale-staining vacuolated or reticulated cytoplasm, as in viral hepatitis or in degenerated epidermal cell's in herpes zoster, a large form of nevus cell with abundant nonstaining cytoplasm, formed by vacular degeneration of melanosomes. (05 Mar 2000) |
| balloon cell nevus | A nevus in which many of the cells are large, with clear cytoplasm. (05 Mar 2000) |
| balloon counter pulsation | A form of circulatory assistance in which a balloon inflates in the aorta during diastole to improve diastolic pressure and deflates during systole to reduce left ventricular after load. (05 Mar 2000) |
| balloon dilatation | Nonoperative repair of occluded vessels, ducts, or valves by insertion of a balloon catheter. It is used to treat varices, torn retinas, renal and biliary calculi, gastric, bronchial and rectal stenoses, and heart valves, and includes catheterization with fogarty and foley catheters. (12 Dec 1998) |
| balloon fish | <zoology> A fish of the genus Diodon or the genus Tetraodon, having the power of distending its body by taking air or water into its dilatable oesophagus. See Globefish, and Bur fish. Source: Websters Dictionary (01 Mar 1998) |
| balloon sickness | A form of mountain sickness occurring in someone as a result of ascent in a balloon. (05 Mar 2000) |
| balloon-tip catheter | A tube with a balloon at its tip that can be inflated or deflated without removal after installation; the balloon may be inflated to facilitate passage of the tube through a blood vessel (propelled by the bloodstream) or to occlude the vessel in which the tube alone would allow free flow; such catheter's are used to enter the pulmonary artery to facilitate haemodynamic measurements or to enter arteries and then remove them while inflated to withdraw clots (embolectomy catheter). See: Swan-Ganz catheter. Synonym: Fogarty catheter. (05 Mar 2000) |
| balance disorder |
A balance disorder is a disturbance that causes an individual to feel unsteady, giddy, woozy, or have a sensation of movement, spinning, or floating. An organ in our inner ear, the labyrinth, is an important part of the vestibular system which is responsible for balancing the body. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body's position. ...

| ball |
In baseball, the strike zone is a conceptual rectangular area over home plate which defines the boundaries through which a pitch must pass in order to count as a strike when the batter does not swing. The top of the strike zone is the mid-level between the top of the batter's shoulders and his belt, and the bottom is at the level just beneath the knee cap. The right and left boundaries of the strike zone correspond to the edges of home plate. ...

| ball-and-socket joint |
----A joint is the location at which two bones make contact. Structurally, the joints are classified as:*fibrous - bones are connected by fibrous connective tissue.*cartilaginous - bones are connected by cartilage.*synovial - there is a space (synovial cavity) between the articulating bones.Functionally, they can be classified as:*synarthrosis - permit no movement.*amphiarthrosis - permit little movement.*diarthrosis - permit a variety of movements (e.g. flexion, adduction, pronation). ...
