Aortic arches development

Animation of the developing aortic arches. I made this video for an Embryology class @BYU-I using Motion 4. I basd the animation on the diagram made by Ben Bryner on the UMMS website. http://www-personal.umich.edu/~dsaddawi/med2008/resources/aortic%20arches.jpg

what is the blue part called?

[ryanktolman]

If your question is about the DARK BLUE part:

The parts of the dark blue "V" start out as the dorsal aortae (left dorsal aorta & right dorsal aorta) and the descending aorta (the bottom of the "V").

Segments of each dorsal aorta between the 3rd (red) and 4th (green) aortic arches disappear around the 5th week.

[ryanktolman]

@ryanktolman During 7th week, the right dorsal aorta (or the left side of the dark blue "V" in the video) separates from the descending aorta and connects the right 7th intersegmental artery (bottom-left-white part in the video) with the right 4th aortic arch (left-green part in the video) to eventually create the right subclavian artery.

SO… the right subclavian artery is made of: 4th+ a segment of the right dorsal + right 7th, which in the video is = green + dark blue + white right.

[ryanktolman]

@ryanktolman The top portions of the dorsal aortae (the "tips" of the dark blue V in the video) become the left and right internal carotid arteries.

The lower left segment of the dorsal aorta (lower-right-dark blue part in the video) becomes the descending descending aorta.

@Randayman If your question is about the BRIGHT BLUE part:

The bright blue part starts out as the truncus arteriosus. It eventually becomes the pulmonary trunk (bright blue part that's on top of the other bright blue part and connected to the 6th or pink aortic arch in the video) and the ascending aorta (bright blue part that's UNDER the bright blue pulmonary trunk and connected to the brown ascending aorta/aortic sac).

Hope that answered your question!

Go BYU-I. Using this for a med school study group - hope you don't mind! :)

@72potter  Glad to hear it's being used!

@ryanktolman

yes it did

thx doctor so much

this video is more than great
