MedicalSeeMOVEMENT OF RIB CAGE AND DIAPHRAGM DURING RESPIRATION: A. Inspiration: Air drawn into lungs; B. Expiration: Air forced out of lungs4. The dome-shaped skeletal muscle that separates the abdomen from the thoracic cavity with its convexity upward. It contracts to promote inhalation, flattening downward and permitting the lungs to expand. It relaxes to promote exhalation, rising to its dome-shaped position and compressing the lungs.

The origin of the diaphragm is the xiphoid process, the lower six costal cartilages, and the lumbar vertebrae. The diaphragm is directly superior to the liver, the stomach, the spleen, the adrenal glands, and the kidneys; the right side is slightly higher than the left. See: illustration; Boerhaave syndrome

Bucky diaphragm

hernia of diaphragm

A congenital or traumatic protrusion of abdominal contents through the diaphragm.

pelvic diaphragm

Pelvic floor.

Potter-Bucky diaphragm

slit diaphragm

A gap between the foot processes of podocytes in the renal glomerulus, composed of a filter made of proteins that holds large molecules within the plasma but allows smaller soluble chemicals to pass with water into the urine.

urogenital diaphragm

The urogenital trigone, or triangular ligament. A musculofascial sheath that lies between the ischiopubic rami, it is superficial to the pelvic diaphragm. In males it surrounds the membranous urethra; in females, the vagina. illustration

diaphragm

1. The dome-shaped muscular and tendinous partition that separates the cavity of the chest from the cavity of the abdomen. When the muscle contracts the dome flattens, thereby increasing the volume of the chest. 2. Any partitioning structure, such as the iris diaphragm of the eye.

diaphragm

a sheet of tissue present only in mammals, that separates the thorax from the abdomen. It consists mainly of muscle and tendons, and has openings through which the oesophagus, blood vessels and nerves pass. Its flattening from a convex position projecting into the thorax is an important aspect of the expansion of the lungs as inspiration takes place. See BREATHING.
a hemispherical rubber cap fitted inside the vagina over the neck (cervix) of the uterus and acting as a contraceptive for BIRTH CONTROL.

Diaphragm

diaphragm

1. In optics, an aperture generally round and of variable diameter placed in a screen and used to limit the field of view of a lens or optical system (field stop). It also limits stray light (light stop). Syn. stop; aperture-stop. 2. In anatomy, a dividing membrane.

di·a·phragm

(dī'ă-fram) [TA] 1. [TA] Musculomembranous partition between abdominal thoracic cavities. 2. In radiography, a grid (2) or a lead sheet with an aperture.
See: collimator3. A thin disc pierced with an opening, used in a microscope, camera, or other optic instrument to shut out the marginal rays of light, thus giving a more direct illumination. [G. diaphragma]
