Polyps
|
|
Polyps An abnormal growth of a mucous membrane, often in the nasal passages, bladder, rectum, or uterus. Polyps, though often benign, have been associated with cancers and can be surgically removed.
RELATED TERMS--------------------------------------
Abnormal
Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Mucous
Adj. Relating to or resembling mucus.
Membrane
A flexible layer surrounding a cell, organelle (such as the nucleus), or other bodily structure. The movement of molecules across a membrane is strictly regulated in both directions.
Bladder
A muscular triangular-shaped, hollow organ located in the pelvic cavity and supported by the pelvic floor muscles. The bladder stretches to store urine and contracts to release urine.
Rectum
An 8-inch chamber connected to the large intestine that receives solid waste (feces) from the descending colon to be expelled from the body. The rectum connects the colon to the anus. It is the rectum's job to receive stool from the colon, to let the person know that there is stool to be evacuated, and to hold the stool until evacuation happens.
Uterus
The uterus is a hollow, pear-shaped organ located in a woman's lower abdomen, between the bladder and the rectum, that sheds its lining each month during menstruation and in which a fertilized egg (ovum) becomes implanted and the fetus develops.
Polyps
An abnormal growth of a mucous membrane, often in the nasal passages, bladder, rectum, or uterus. Polyps, though often benign, have been associated with cancers and can be surgically removed.
Benign
Non-malignant; not life-threatening.

Polycystic Kidney Disease
A rare inherited condition in which the kidney are composed of multiple cysts. Kidney cysts are associated with an increased incidence of cerebral aneurysm. Symptoms usually appear later (if they do at all) and include blood in the urine, flank pain, excessive urination at night and abdominal pain. Individuals may also have elevated blood pressure. Chronic (end-stage renal disease) renal failure is the most common result in the 5th to 6th decades of life.
Polycystic Ovarian Syndrome
PCOS is a disorder in which the ovaries produce excessive amounts of male hormones (androgens) and develop many small cysts. Symptoms commonly include heavy, irregular or missed periods as well as acne, excessive hair growth on the face, obesity and infertility.
Polycystic ovary syndrome
Clinical symptom complex characterized by oligomenorrhea or amenorrhea, anovulation, and regularly associated with bilateral polycystic ovaries.
Polycystic Ovary Syndrome (PCOS)
A syndrome associated with bilateral polycystic ovaries and insulin resistance. Symptoms frequently include decreased menstrual flow, irregular menses, anovulation, and infertility.
Polycythemia
Abnormal increase in the number of red blood cells or hematocrit.
Polycythemia vera
Polycythemia vera is an abnormal increase in blood cells (primarily red blood cells) resulting from excess production by the bone marrow.
Polydactyly
Extra fingers or toes.
Polydipsia
Excessive thirst.
Polyhidrosis
Excessive sweating.
Polyiterophilia
A form of hyperphilia in which a person's own erotosexual responsiveness is built up toward orgasm by reiterating the same activity (manual, oral, anal, vaginal, or penile) many times with many partners.
Polymerase chain reaction
An in vitro method for enzymatically synthesizing and amplifying defined sequences of DNA in molecular biology. Can be used for improving DNA-based diagnostic procedures for identifying unknown BW agents.
Polymerase Chain Reaction (PCR)
PCR. A method for amplifying a DNA base sequence using a heat-stable polymerase and two 20-base primers, one complementary to the (+) strand at one end of the sequence to be amplified and one complementary to the (-) strand at the other end. Because the newly synthesized DNA strands can subsequently serve as additional templates for the same primer sequences, successive rounds of primer annealing, strand elongation, and dissociation produce rapid and highly specific amplification of the desired sequence. PCR also can be used to detect the existence of the defined sequence in a DNA sample.
Polymorphism
Literally, "having many shapes"; in genetics polymorphism means occurring in more than one form within a species; the existence of multiple alleles at a particular genetic locus.
