Cauliflower-ear deformity
Cauliflower-ear deformity Destruction of the underlying cartilage framework of the outer ear (pinnae), usually caused by either infection or trauma, resulting in a thickening of the ear. Classically, blood collects (hematoma) between the ear cartilage and the skin. There is a marked thickening of the entire ear which may be so extensive that the shape of the ear becomes unrecognizable. The ear is said to look like a piece of cauliflower. It is typically seen in wrestlers and boxers who have had repeated trauma to the ear.
RELATED TERMS--------------------------------------
Cartilage
A firm, flexible connective tissue. In vertebrates, the cartilage forms the skeleton in the early stages of development, after which it is largely replaced by bone. Some cartilage remains at the joints to give flexibility and support.
Infection
Anything that invades the body and reproduces. Infections can be bacteria, protozoa, fungi, or viruses. Bacteria and fungi are one celled creatures that cause many infections including strep throat, bladder infections, and some lung infections. Fungi cause “athlete’s foot” and thrush, an infection in the mouth. Protozoa are small organisms with many cells that can cause infections in the guts or in the lungs. Most healthy people do not get protozoal infections, but people with suppressed immune systems can. Viruses are not really organisms; they are tiny particles that can live only inside another cell. They reproduce by taking over a cell and causing that cell to make more virus particles, rather than doing what the cell is supposed to do. Viruses cause most colds and flu cases.
Trauma
Injury caused by external force, chemical, temperature extremes, or poor tooth alignment.
Ear
The hearing organ. There are three sections of the ear, according to the anatomy textbooks. They are the outer ear (the part we see along the sides of our head behind the temples), the middle ear, and the inner ear. But in terms of function, the ear has four parts: those three and the brain. Hearing thus involves all parts of the ear as well as the auditory cortex of the brain. The external ear helps concentrate the vibrations of air on the ear drum and make it vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear. There they stimulate the fibers of the auditory nerve to transmit impulses to the brain.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Skin
Skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. Skin is used for insulation, vitamin D production, sensation, and excretion (through sweat).
SIMILAR TERMS--------------------------------------
Caul
In obstetrics, the caul is the amnion, one of the two fetal membranes, the other being the chorion. To be born in a caul meant to be born with the head covered by the amnion (or be born within an intact unruptured amnion). To be born in a caul was long believed to be a sign of future greatness.
Cauliflower ear
A trauma-induced deformity of the ear caused by repeated cartilage and soft-tissue injury.
Caulophyllum thalictroides
Blue cohosh.
PREVIOUS AND NEXT TERMS--------------------------------------
Cauda equina
A bundle of spinal nerve roots that arise from the bottom end of the spinal cord. The cauda equina comprises the roots of all the spinal nerve roots below the level of the first lumbar (L1) vertebra, namely the sacral and coccygeal nerves. So named because it resembles the tail (Latin, cauda) of a horse (Latin, equus). See also Cauda equina syndrome.
Caudad
Toward the feet (or, in embryology, toward the tail), as opposed to cranial. The spinal cord is caudad to the brain.
Caudal anesthesia
Anesthesia produced by injection of a local anesthetic into the caudal canal, the sacral portion of the spinal canal. Caudal anesthesia is used to provide anesthesia and analgesia (pain relief) below the umbilicus. It may be the sole anesthetic or combined with general anesthesia. Also called caudal epidural anesthesia or a caudal block.
Caudate nucleus
In each hemisphere of the brain, the most medial of the four basal ganglia, partly responsible for body movement and coordination. So named because it looks anatomically tail-like.
Caul
In obstetrics, the caul is the amnion, one of the two fetal membranes, the other being the chorion. To be born in a caul meant to be born with the head covered by the amnion (or be born within an intact unruptured amnion). To be born in a caul was long believed to be a sign of future greatness.
Cauliflower-ear deformity
Caulophyllum thalictroides
Blue cohosh.
Causes of cancer
Cancer is a group of more than 100 different diseases. Benign tumors are not cancer; malignant tumors are cancer. Most cancers are named for the type of cell or the organ in which they begin. When cancer spreads (metastasizes), the new tumor has the same name as the original (primary) tumor. Skin cancer is the most common type of cancer for both men and women. The second most common cancer in men is prostate cancer, in women it is breast cancer.
Cauterization
The use of heat to destroy abnormal cells. Also called diathermy or electrodiathermy.
Caution codes, drug
Abbreviations on medications that indicate caution.
Caveola
An tiny pit, grotto, depression, incupping in the surface of a cell. The name "caveola" means little cave. The plural is caveolae.
