Question

1. which of the following may be caused by coronary thrombosis?

mitral valve insufficiency
pulmonary valve atresia
aortic valve stenosis
myocardial infarction

1. tim has epispadias, meaning there is:

a defect in the bottom of the urethra
a defect in the top of the urethra
a defect in testicles descending into scrotal sac
testicular torsion

Explanation:

• Question 63: Coronary thrombosis refers to the formation of a blood clot in a coronary artery. This can block blood flow to the heart muscle, leading to myocardial infarction (heart attack). Mitral valve insufficiency, pulmonary valve atresia, and aortic valve stenosis are valve - related disorders not directly caused by coronary thrombosis.
• Question 64: Epispadias is a congenital disorder where there is a defect in the top (dorsal) surface of the urethra. A defect in the bottom (ventral) surface of the urethra is hypospadias. A defect in testicles descending into the scrotal sac is cryptorchidism, and testicular torsion is a twisting of the spermatic cord.

Answer:

1. myocardial infarction
2. a defect in the top of the urethra
