1) The valve consisting of three cusps situated between the right atrium and right ventricle of the heart.
2) A valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps -- called also right atrioventricular valve.

1) The visualization of deep structures of the body by recording the reflections of echoes of pulses of ultrasonic waves directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
2) High frequency sound waves used to identify and examine internal organs and structures without the invasive hazards of X xays, dyes, or fluoroscopy.
3) A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

1) Thickened nails.
2) Extreme usually congenital thickness of the nails.

1) Thickening and loss of elasticity of the coronary arteries, leading to progressive insufficiency of the arteries (coronary disease).
2) A condition and especially one caused by atherosclerosis that reduces the blood flow through the coronary arteries to the heart muscle and typically results in chest pain or heart damage -- called also coronary disease, coronary heart disease.
3) A disease in which there is a narrowing or blockage of the coronary arteries (blood vessels that carry blood and oxygen to the heart). Coronary heart disease is usually caused by atherosclerosis (a build up of fatty material and plaque inside the coronary arteries). The disease may cause chest pain, shortness of breath during exercise, and heart attacks. The risk of coronary heart disease is increased by having a family history of coronary heart disease before age 50, older age, smoking tobacco, high blood pressure, high cholesterol, diabetes, lack of exercise, and obesity. Also called coronary artery disease and CAD.

1) Thin leaf-shaped cartilage, covered with mucous membrane, at the root of the tongue, which folds back over the entrance to the larynx, covering it, during the act of swallowing.
2) The flap that covers the trachea during swallowing so that food does not enter the lungs.

1) This carcinoma comprises less than 10% of all thyroid cancers. This specific type as significant diagnostic importance because of its aggressive nature and its close association with multiple endocrine neoplasia syndromes. Approximately 10% to 20% of medullary thyroid carcinoma is familial. Patients usually present with a thyroid nodule that is painless and firm. In the majority of cases nodal metastases is present at diagnosis. Surgery is the preferred treatment for both primary therapy and recurrent cases. It is generally not very sensitive to radiation and almost unresponsive to chemotherapy. - 2002
2) Cancer that develops in C cells of the thyroid. The C cells make a hormone (calcitonin) that helps maintain a healthy level of calcium in the blood.
