abdominal cavity (ab DAHM uh nuhl KAHV i tee) (s) (noun), abdominal cavities (pl)
1. The space between the stomach area and the spine which contains a number of crucial organs: The abdominal cavity includes the lower part of the esophagus, the stomach, small intestine, colon, rectum, liver, gallbladder, pancreas, spleen, kidneys, adrenal glands, ureters, bladder, as well as associated tissues and blood and lymphatic vessels all of which are surrounded by the flat band of fibrous tissue below the skin that covers the underlying tissues and separates the different layers of tissue.
2. Etymology: from Latin abdomen, abdominis, "belly" and from medical Latin abdominalis.

The stomach (which is in the abdominal area) is lined with thirty-five million glands that produce about three quarts (2.85 liters) of gastric juices daily. Hydrochloric acid makes up roughly five percent of these juices and, together with other acids and various enzymes, constantly works to digest food particles.

1. A hands-on evaluation of the abdominal cavity to identify abnormalities, if there are any, based on a change in size, shape, consistency, or sound on percussion of the organs found inside: Because Voni was experiencing pains in her stomach, Dr. Black performed an abdominal examination to see what was causing Voni's symptoms of discomfort.
2. The physical evaluation of a patient's midsection with visual inspection, auscultation, percussion, and palpation: An abdominal examination includes the visual examination of the normally oval shape of the abdominal surface while the patient is lying on his or her back which may reveal abnormal surface features indicating the effects of a disease, surgery, or injury.

Below the surface, tumors, fluid accumulation, or hypertrophy of the liver or spleen may be seen as an abnormal surface feature.

Auscultation, or listening to sounds within the body, usually with a stethoscope, may reveal vascular sounds that provide information about arterial disorders, such as aortic aneurysms of the aorta and bowel sounds that indicate intestinal function.

In a pregnant patient, auscultation can detect fetal heartbeat and blood circulation in the placenta.

Percussion, the tapping of a part of the body for diagnostic purposes, helps to determination the condition of internal organs while palpation, or feeling the size, shape, or firmness of body parts, is used to detect areas of tenderness or rigidity, muscle tone and skin condition, and the shapes and sizes of organs or masses under the surface of the skin.

abdominal muscles (pl) (noun)
1. A large group of muscles in the front of the abdomen that assists in the regular breathing movement and supports the muscles of the spine while lifting and keeping abdominal organs, such as the intestines in place.
2. The group of four muscles which make up the abdominal wall consists of:

  • The external oblique (the most superficial of the four, a muscle from the fifth to twelfth ribs) whose fibers are directed downward and medially from the lower ribs to the linea alba (a fibrous band) and pelvis.
  • The internal oblique (a slanting, small, thin, deep muscle of the abdomen), whose fibers are directed upward and medially from the iliac crest (hip bone) and lumbodorsal fascia (loose tissue) to the lower ribs.
  • The rectus abdominis, a vertically oriented muscle from the crest of the pubis (pelvis) to the cartilages of the fifth, sixth, and seventh ribs and xiphoid process.
  • The transversus abdominis, whose fibers are oriented transversely (sideways or at an angle across something).

These muscles participate in a variety of functions, including flexion, side bending and rotation of the trunk, stabilization of the trunk in the upright posture, the expiratory phase of respiration, coughing, and Valsalva's maneuver.

The term "Valsalva's maneuver" is a maneuver in which the patient holds his or her breath or gives a voluntary cough or sneeze to produce pain.

These activities of holding the breath, coughing, or sneezing increase the pressure of the cerebrospinal fluid which enlarges the pressure against the already pressured nerve, causing pain and numbness. The location of this intensified pain also contributes to the medical diagnosis.

Both muscles acting together serve to flex the vertebral column, drawing the costal cartilages toward the pubis. One side acting alone bends the vertebral column laterally and rotates it, drawing the shoulder of the opposite side downward.
