________ Right Recurrent Laryngeal Nerve

Question

________ Right recurrent laryngeal nerve
A)Ductus arteriosus
B)Septum primum
C)Sixth pharyngeal arch artery
D)Sinus venosus
E)Umbilical vein

Accepted Answer

The right recurrent laryngeal nerve hooks around the right subclavian artery, which is derived from the fourth pharyngeal arch artery on the right side. However, the question mentions the sixth pharyngeal arch artery, which is related to the development of the ductus arteriosus and the pulmonary arteries. The left recurrent laryngeal nerve hooks around the aortic arch, and this arch is closely related to the sixth pharyngeal arch artery's development. The confusion might stem from the developmental intricacies of these structures, but the right recurrent laryngeal nerve's course is not directly related to the sixth pharyngeal arch artery. The correct developmental correlation for the right recurrent laryngeal nerve involves its relationship with the right subclavian artery, which is not an option provided here. Therefore, the question as posed does not accurately reflect the anatomical development of the right recurrent laryngeal nerve based on the provided options.
