I am a head and neck surgeon . I wish to know how common is it to find a 3rd head of sterno cleido mastoid(SCM).Ialso would like to know the incidence of levator gladulae throidae.
I hope you are still amoung our members.
I was disecting Humen crpses for 7 years.
Total of arround 200 corpses , and I saw maybe once a third head from the first rib.
