As Cara worked at her dissection, she became frustrated that several of the structures she had to learn about had more than one common name. Provide another name for each of these structures: a. atrioventricular groove, b. tricuspid valve, c. bicuspid valve (give two synonyms), and d. atrioventricular bundle.

Hi, everyone. Welcome back. Let's look at our next question, which of the following terms is accurately matched with a corresponding structure. So we've got four different pairs here and we'll go through them one by one. We recall the only one will be a correct pairing. So choice A says coronary sulcus and Tricuspid valve. Well, the corner sulcus is the groove, the major groove on the outside of the heart between the atria and the ventricles. While the tricuspid valve is located between the right atrium and the right ventricle. So these are not correctly paired. The tricuspid valve is not in the coronary sulcus. So we'll cross that out and move on to B B says atrioventricular sulcus and atrioventricular groove. Well, these are different names for the same thing. They also are the same as the Coronary circus we mentioned in the previous choice. So they're all the same structure. So we'll go ahead and choose that as our correct answer as these are different names for the same structure. So that would be a correct pairing. Let's be thorough and keep going here. Choice C says right atrioventricular valve and bicuspid valve. Well, the right a ventricular valve is another name for the tricuspid valve. We've already run across and it is not the same thing as the bicuspid bell, which is between the left atrium and ventricle. So they're corresponding structures but on the opposite sides of the heart. So not uh correct matching. So we'll cross that off and finally choice d the bundle of hiss and the mit valve. Well, the microvalve is another name for the bicuspid valve that valve between the left atrium and vegetables. While the bundle of his is something completely different. Um It's a collection of heart muscle cells that are specialized for electrical conduction and it transmits from the A V node to the ventricles and helps to coordinate the beating of the different parts and the other, the contraction of the different parts of the heart. So a completely different thing than the bicuspid valve or the micro valve. So choice D also not a correct match. So again, the term accurately matched with its corresponding structure is choice B the atrioventricular sulcus with the atrioventricular groove, they are one and the same thing. See you in the next video.
