Bulging of the bladder into another part. Hernia of the bladder into the vagina. A bladder hernia, also known as a cystocele, is a condition where the bladder prolapses or falls out of its normal position. It is most commonly observed in women, particularly those whose vaginal support muscles have been weakened by multiple childbirths.…

Serious disturbance in cardiac rhythm, characterized by disorganized impulse conduction and ventricular contraction. Unconsciousness occurs and death may follow within minutes if defibrillation and other life-saving measures are not immediately provided. Rapid but ineffective movements of the ventricles of the heart that replace coordinated contractions, resulting in grossly diminished cardiac output. Grossly abnormal heartbeat, sometimes…

Localized dilation or saccular protrusion on the wall of the left ventricle of the heart occurring after a myocardial infarction. An inflated protrusion in the wall of the left ventricle of the heart (the chamber responsible for circulating oxygen-rich blood throughout the body). Typically arising from a myocardial infarction (heart attack), ventricular aneurysm can subsequently…

Ventres, belly-like part, as the bulging part of a muscle. The abdominal region. Any part resembling a rounded or belly-shaped structure, such as the contractile segment of a muscle.  

Any of several sinuses that collect blood from the dura mater covering the brain and drain it into the internal jugular veins. A large-capacity vessel that carries venous blood. Important venous sinuses are those of the dura mater draining the brain and those of the spleen.  

Stress exerted by the circulating blood on the walls of the veins. The pressure of the blood within the veins. It is highest near the periphery, diminishing progressively from capillaries to the heart. Near the heart the venous pressure may be below zero (negative pressure) owing to negative intrathoracic pressure. The pressure of blood inside…

Oxygen and carbon dioxide levels in venous blood.  

Technique of preparing X-ray images of a vein injected with a radiopaque contrast medium. X-ray examination of the veins after injection of dye that absorbs the x-rays. A radiographic procedure that shows the internal structures of veins after the patient receives an injection of contrast medium. X-ray examination to show up the course of veins…

Ray film of veins injected with a radiopaque contrast medium.  

Any of three muscles that form part of the quadriceps muscle of the thigh. Any of three muscles (vastus intermedius, vastus lateralis, and vastus medialis) that form part of the quadriceps muscle of the thigh.
