When the diaphragm contracts, does it affect the aorta?
a. Yes, because the aorta passes through the aortic hiatus when entering the abdomen so, the diaphragmatic muscle will constrict the hiatus
b. Yes, because the aorta passes through the aortic hiatus which is formed by the diaphragm on one side and the vertebral column on other side, the contractions of the muscle will push the aorta towards the vertebral column and minimize the diameter of the aorta
c. No, because the aorta passes through the aortic hiatus, which is a tendinous one, not muscular, and it’s located posterior to the xifoid process of the sternum
d. No, because the aorta has nothing to do with the diaphragm
e. No, because the aortic hiatus is located between the median arcuate ligament anterior, vertebral column posterior and diaphragmatic crura lateral, basically posterior the muscular part of the diaphragm, this way the contractions of the muscle do not affect the aorta
The most accurate answer is:
e. No, because the aortic hiatus is located between the median arcuate ligament anterior, vertebral column posterior, and diaphragmatic crura lateral, basically posterior to the muscular part of the diaphragm. This positioning means that contractions of the diaphragm do not significantly affect the aorta.
