Diaphragm

The diaphragm is the thin, dome-shaped muscular partition which separates the cavity of the abdomen from that of the chest. It is of great importance in respiration, playing the chief part in ?lling the lungs. During deep respiration its movements are responsible for 60 per cent of the total amount of air breathed, and in the horizontal posture, or in sleep, an even greater percentage.

The description ‘diaphragm’ is also used for the hemispherical rubber (‘dutch’) cap used in conjunction with a chemical spermicide as a contraceptive. It ?ts over the neck of the uterus (cervix) inside the vagina. (See CONTRACEPTION.)... diaphragm

Diaphragm, Contraceptive

A female barrier method of contraception in the form of a hemispherical dome of thin rubber with a metal spring in the rim.

(See also contraception, barrier methods.)... diaphragm, contraceptive

Diaphragm Muscle

The dome-shaped sheet of muscle that separates the chest from the abdomen. It is attached to the spine, ribs, and sternum (breastbone)

and plays an important role in breathing. There are openings in the diaphragm for the oesophagus and major nerves and blood vessels. To inhale, the diaphragm’s muscle fibres contract, pulling the whole diaphragm downwards and drawing air into the lungs. (See also breathing.)... diaphragm muscle

Congenital Diaphragmatic Hernia

(CDH) herniation of the fetal abdominal organs into the fetal chest, which occurs in one in 2000–5000 live births. This leads to pulmonary *hypoplasia, which is the main cause of the associated high neonatal mortality. The risk of pulmonary hypoplasia is substantially greater where there is herniation of the liver into the thoracic cavity. CDH is commonly associated with additional structural abnormalities (cardiac, neural tube defects, and exomphalos), and the risk of chromosomal abnormality (*aneuploidy) is 10–20%.
