Use of electrical stimulation to compete with pain stimuli for transmission to the spinal cord; may be delivered through the skin or by an implantable device. Relief from pain by application of low-intensity electric currents locally or through implanted electrodes.  

An abnormal cardiac sound produced by pumping of blood into the aorta or pulmonary arteries that stops prior to the closure of the aortic or pulmonic valves. A systolic murmur that is most intense at the time of maximum flow of blood from the heart. This murmur is associated with pulmonary and aortic stenosis.  

The unabsorbed food fragments that are passed through the digestive tract. Waste matter eliminated from the body, especially excrement.

Conditions produced from sources outside of the body; disease that is caused by events outside the body such as infections or traumatic injury. Originating outside a body or structure, as infection. Able to grow outside the body, commonly in reference to parasites or microorganisms.  

Characteristic of body tissues that resonate echoes of sound which are captured under ultrasound examination. Capable of producing echoes, i.e., of intensely reflecting sound waves rather than transmitting them. In ultrasound scanning, the term “echogenic” is used to describe a structure that produces reflections (echoes) of ultrasound waves.
