(Almighty's peace on all), if anyone out here specially anatomists who often get to see variations in routine dissections help me know if someone has found bilateral cleido-hyoid muscle in neck dissection rather than omo-hyoid, as variation
i am currently working out a paper on an other variation, i shall keep in mind, will get back to you then, thank you
We see variations frequently in our cadavers. One of the most recent was a female whose left vertebral artery arose directly off the aortic arch instead of the left subclavian artery. I have not seen this variation in the hyoid muscles.
yes sir, its true that there are lot variations seen in most of cadavers, but most of the variations are unilateral, rarely is any variation seen bilaterally. may be there are many variations left unnoticed due to carelessness or lack of thorough knowledge of the area dissected. thank you for your reply, regards.
Vertebral artery origin from aorta is because of failure
of 7th cervical inter seg mental artery participation.this anomaly is not uncommon
7th intersegmental artery is consumed in formation of part of Subclavian artery.
