I noticed this also. I looked at a few resources, and it looks like the inferior gluteal can branch off from either the anterior or posterior division of the IIA. I guess, the most important thing is to figure out where it actually goes. Not sure how you would go about this on an angiogram though.
Fantastic video. With regards to people's questions regarding the inferior gluteal artery, I quote Hollinshead, 5th edition p648: There is great variation in the precise branching patter of the internal iliac artery. Nice major types of branching and 49 subtypes have been described. . . . Of the two gluteal arteries the inferior is usually given off by the anterior trunk of the internal iliac and the superior gluteal artery is usually given off by the posterior trunk.
I really like your video but there is a MISTAKE and people should know if they are using this to study. Like others have stated, the inferior gluteal a. is a branch off of the anterior trunk NOT the posterior trunk
I’m just going to defend Dr. Pickering here. Many anatomists nowadays refuse to classify the branches of the internal iliac artery because of its sheer vast variation. Indeed, although it is still clasically classified thus, many accept that the inferior gluteal artery can quite often arise from the posterior trunk of the internal iliac artery. So its not “wrong”, as many state, but is not clasically described thus. Anatomy is variation, it is not the textbook - flexibility people!!!
Ran out of characters sorry. It all comes down to how you learn them. If your professor will test you on the divisions and prefers adding the visceral division then by all means do it. A good question to your professor would be why add the visceral division to the anterior and posterior divisions which define location instead of defining the divisions for WHAT they supply: Muscle and Visceral divisions...hope that helps, cheers.
It's such a simplified video, though I think it would be better that you give the most accepted anatomical features. More so the variations of the inferior gluteal. Thank you, though, Dr.
It's not a matter of right or wrong rather how you prefer to separate the branching. You can call the nerves supplying the viscera a separate visceral division or you can include them in the anterior division because they are in fact 'anterior.' He uses "posterior and anterior division" method to denote location. If you want to separate them based on what they supply then ya you can use visceral division although it would make more sense to divide them into muscular and visceral divisions..
He said that in women there's no inferior vesical artery; however, Thieme Anatomy Atlas says that there's actually an inferior vesical artery in women that irrigates the urinary bladder. Another thing is that he drew the inferior gluteal artery from the posterior trunk of the internal iliac artery. I know all this is highly variable, but it's usually the case that inferior gluteal artery comes from the anterior trunk as the terminal branch of the anterior trunk, and not from the posterior.
Coccygeus Muscle originates from ischial spine and inserts into lower end of sacrum and coccyx bone_ (Snell Clinical Anatomy).. He mixed the attachements..
Please make a CORRECTION: Inferior Gluteal Artery arises from the Anterior Trunk(& NOT from the posterior trunk as shown in the video). Please refer to the wikipedia article: en.wikipedia.org/wiki/Inferior_gluteal_artery
ok man is accepted the divisions but posteriorly we have superior gluteal artery, iliolumbar artery and lateral sacral artery. inferior gluteal is from anterior branch
