A disorder of the heart’s electrical system that predisposes individuals to irregular heartbeats, fainting spells, and sudden death. The irregular heartbeats are typically brought on by stress or vigorous activity. Abbreviated LQTS. LQTS is often symptomless and undiagnosed, but it is well known as a cause of sudden cardiac death in young, apparently healthy people, most notably competitive athletes.…

The long arm of a chromosome is termed the q arm. All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division. The symbol “p” stands…

In genetics, a statistical estimate of whether two loci (the sites of genes) are likely to lie near each other on a chromosome and are therefore likely to be inherited together as a package. LOD stands for logarithm of the odds (to the base 10). A LOD score of three or more is generally taken to indicate that…

Latin meaning a place of less resistance. A locus minoris resistentiae offers little resistance to microorganisms. For example, a damaged heart valve acts as a locus minoris resistentiae, a place where any bacteria in the bloodstream tend to settle. The concept of a locus minoris resistentiae is an old one but still a valid, useful way of…

Limited to a local region.

The bones, the joints, and the muscles that contract and relax to move the joints and bones.

Movement from one place to another. And the ability to locomote, to get from one place to the next. The locomotive system permits locomotion and consists of bones that are the framework of the skeleton, joints that hold the bones together and make movement possible, and muscles that contract and relax and make for movement. Locomotion is derived from…

The fluid that is discharged from the vagina for a week or so after childbirth. At first the lochia is primarily blood, followed by a more mucousy fluid that contains dried blood, and finally a clear-to-yellow discharge.

Treatment that affects the tumor and the area close to it.

Part of an organ that appears to be separate in some way from the rest. A lobe may be demarcated from the rest of the organ by a fissure (crack), sulcus (groove), connective tissue or simply by its shape. For example, there are the frontal, parietal, temporal, and occipital lobes of the brain. The word “lobe” from the Greek lobos meaning “a small rounded projection” long applied only to the…
