THE INNERVATION OF INFRAHYOID MUSCLES / 解剖学报

ABSTRACT

Among the 100 cases studied,all showed that prethyroid muscles are innervated by the upper and lower nerve branches from the ansa hypoglossi.Although the position and height of the site of entrance of the nerve into the muscle is not constant,yet it is advisable to cut the prethyroid muscles at the level of the height of isthmus of thyroid gland during the operation of thyroid gland,in order to avoid or at least to decrease the possibility of the injury of the nerve supply of the muscles.
