A painful swelling of the bursa of the first joint of the big toe.
Inflammation of the joint between the big toe and the first metatarsal bone. It tends to displace the big toe inward. It is due to the wearing of ill-fitting shoes.
Insensitivity; the state of being callous; hard and indifferent.
ETYM Latin See Callous.
(Irregular plural: calluses).
In botany, a tissue that forms at a damaged plant surface. Composed of large, thin-walled parenchyma cells, it grows over and around the wound, eventually covering the exposed area.
In animals, a callus is a thickened pad of skin, formed where there is repeated rubbing against a hard surface. In humans, calluses often develop on the hands and feet of those involved in heavy manual work.Growth of healing tissue, also containing blood and bone-forming cells, that forms around the ends of a bone following a fracture. Callus formation is an important factor in the union of the fracture.
1. Bony tissue formed during the healing of a fractured bone.
2. (Botany) An isolated thickening of tissue, especially a stiff protuberance on the lip of an orchid.
Purple stripe worn on toga by persons of high rank in ancient Rome; corn (on foot); intensely painful headache.
Area of thickened skin on or between the toes. It is usually caused by pressure from part of the shoe. Treatment of painful corns is an important part of chiropody.
Cultivated New World plant Zea mays of the grass family, with the grain borne on cobs enclosed in husks. It is also called corn or Indian corn. It was domesticated by 6,000 BC in Mesoamerica, where it grew wild. It became the staple crop for the Neolithic farming villages and civilizations of Mexico and Peru; it was cultivated throughout most of the New World at the point of European contact. It was brought to Europe, Asia, and Africa by the colonizing powers, but its use is mainly for animal feed in those regions. In the US, a corn monoculture dominates the Midwest, where many hybrids have been developed for both human food and animal feed. Today it is grown extensively in all subtropical and warm temperate regions, and its range has been extended to colder zones by hardy varieties developed in the 1960s.
Corn is eaten fresh (on the cob or creamed), canned (niblets), frozen, and in dried forms (cornmeal, popcorn), and is made into hominy, polenta, cornflour, and corn bread. It is pressed for corn oil and fermented into a mash, which, distilled, is corn liquor (whiskey). Most of the methods of storing, processing, and cooking corn can be traced to Native American recipes. Popcorn has been found in archeological sites in the SW dating from 4,000 BC. Corn stalks are made into paper and hardboard.
1. Tall annual cereal grass bearing kernels on large ears: widely cultivated in America in many varieties; the principal cereal in Mexico and Central and South America since pre-Columbian times; SYN. maize, Indian corn, Zea mays.
2. Ears of corn grown for human food; SYN. edible corn.
3. The dried grains or kernels or corn used as animal feed or ground for meal.
4. A hard thickening of the skin (especially of the toes) caused by the pressure of ill-fitting shoes; SYN. clavus.
1. A skin sore caused by chafing.
2. Abnormal swelling of plant tissue caused by insects or microorganisms or injury.
Abnormal outgrowth on a plant that develops as a result of attack by insects or, less commonly, by bacteria, fungi, mites, or nematodes. The attack causes an increase in the number of cells or an enlargement of existing cells in the plant. Gall-forming insects generally pass the early stages of their life inside the gall.
Gall wasps are responsible for the conspicuous bud galls forming on oak trees, 2.5–4 cm/1–1.5 in across, known as “oak apples”.
