11. The body whorl has semilunar riblets. 12. "Strobilopterus " is distinguishable by its outer surface that has pustules and semilunar scales. 13. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. 14. The inner ear underwent multiple deformations affecting the cochlear duct, semilunar canal, and otic capsule portions. 15. Both chambers are in diastole, the atrioventricular valves are open, and the semilunar valves remain closed. 16. The semilunar aortic valve is at the base of the aorta and also is not attached to papillary muscles. 17. This results in the slight increase in aortic pressure caused by the elastic recoil of the semilunar valves and aorta. 18. The posterior oblique originates at the medial epicondyle and inserts along the mid-portion of the medial semilunar notch. 19. The forewings are dark yellowish-brown with a strongly reduced pattern of weakly semilunar submarginal fascia and blurred medial bands. 20. FAD is normally associated with Marfan syndrome, atrioventricular and semilunar valves due to elastolysis or breakdown and loss of elastic fibers.
