False rib
|
|
False ribOne of the last 5 pairs of ribs. A rib is said to be "false" if it does not attach to the sternum (the breast bone). All 12 pairs of ribs attach to the building blocks of the spine (vertebrae) in the back. The 12 pairs of ribs consist of: True ribs: The first seven ribs attach to the sternum (the breast bone) in the front and are known as true (or sternal) ribs. False ribs: The lower five ribs do not directly connect to the sternum and are known as false ribs. The upper three false ribs connect to the costal cartilages of the ribs just above them. The last two false ribs, however, usually have no ventral attachment (no anchor at all in front) and are called floating, fluctuating or vertebral ribs.
RELATED TERMS--------------------------------------
Sternum
The breastbone.
Breast
The breast refers to the front of the chest or, more specifically, to the mammary gland. The mammary gland is a milk producing gland. It is composed largely of fat. Within the mammary gland is a complex network of branching ducts. These ducts exit from sac-like structures called lobules, which can produce milk in females. The ducts exit the breast at the nipple.
Spine
A column in the body consisting of 33 vertebrae.
SIMILAR TERMS--------------------------------------
False labor
Intermittent non-productive muscular contractions of the womb (uterus) during pregnancy, most commonly in the last two months before full term. These contractions are non-productive in the sense that they do not produce any flattening (effacement) or dilation (opening up) of the cervix.
False negative
A result that appears negative but fails to reveal a situation. An example of a false negative: a particular test designed to detect cancer of the toenail is negative but the person has toenail cancer.
False negative report
A negative result when in reality it is positive in nature.
False positive
A result that is erroneously positive when a situation is normal. An example of a false positive: a particular test designed to detect cancer of the toenail is positive but the person does not have toenail cancer.
False positive report
A positive result when in reality it is negative in nature.
False vocal cord
A fold of mucous membrane covering muscle in the larynx. The false vocal cord separates the ventricle of the larynx from the vestibule of the larynx. Also called the false vocal fold.
PREVIOUS AND NEXT TERMS--------------------------------------
Falciparum malaria
The most dangerous type of malaria. Red blood cells infected with the parasite tend to sludge and form microinfarctions (small areas of dead tissue due to lack of oxygen) in capillaries in the brain, liver, adrenal gland, intestinal tract, kidneys, lungs, and other organs. Treatment is in a hospital setting, using intravenous medications.
FALDH deficiency
Also known as the Sjogren-Larsson syndrome, this is a genetic (inherited) disease usually characterized by a triad of clinical findings consisting of ichthyosis (thickened fish-like skin), spastic paraplegia (spasticity of the legs) and mental retardation.

False rib
False vocal cord
A fold of mucous membrane covering muscle in the larynx. The false vocal cord separates the ventricle of the larynx from the vestibule of the larynx. Also called the false vocal fold.
Familial
A condition that is tends to occur more often in family members than expected by chance alone. A familial disease may be genetic (such as cystic fibrosis) or environmental (such as tuberculosis).
Familial adenomatous polyposis
Abbreviated FAP. A syndrome characterized by the formation of thousands of polyps in the colon and rectum with colorectal cancer the inevitable consequence. Polyps can also occur in the stomach, duodenum and the terminal ileum. The polyps most often begin to form at puberty. And colon cancer usually occurs 10 to 15 years thereafter. The average age of diagnosis of familial polyposis is 25 years of age, with cancers developing at age 20 to 30. However, cancers may arise anywhere from late childhood to the sixties.
Familial ALS
ALS (amyotrophic lateral sclerosis) in which there a family history of the disease. Familial ALS constitutes 5 to 10% of all cases of ALS. There are a number of different types of familial ALS. They are known as ALS1, ALS2, and so on. ALS1 -- caused by mutation in the superoxide dismutase-1 gene (SOD1) on chromosome 21q22.1. About 15 to 20% of familial ALS is type 1 (ALS1). Sporadic cases of ALS are sometimes due to new mutation in the SOD1 gene; ALS2 -- juvenile-onset ALS caused by mutation in the gene encoding alsin on chromosome 2q33; ALS3 -- adult-onset ALS due to mutation in a gene on chromosome 18q21; ALS4 -- juvenile-onset disease with no bulbar involvement due to mutations in a gene on chromosome 9q34; ALS5 -- due to mutations in a gene on chromosome 15q15.1-q21.1; ALS6 -- due to mutations in a gene on chromosome 16q12; ALS7 -- due to mutations in a gene on chromosome 20ptel; ALS8 -- due to mutations in a gene on chromosome 20q13.33. ALS1, ALS3, ALS4, ALS6, ALS7, and ALS8 are inherited in an autosomal dominant manner while ALS2 and ALS5 are inherited in an autosomal recessive manner.
