Located behind the ear, posterior to the anterior border of the ear canal. Opened anteriorly by the large foramen cerebellum. Superiorly it connects with the lambdoid groove at a point located 1 cm above the posterior border of the posterior belly of the sphenoid bone. In front it connects with the suture above the upper edge of the greater horn of the hyoid bone. Below it connects with the occipital notch of the occipital bone.
The carotid groove (lat. sulcus caroticus) is a superficial groove of the neck, formed as a result of fusion of the hyoid bone with the cricoid and thyroid cartilage.\n\nIt has a groove on the lateral surface - the groove of the sternocleidomastoid muscle, in front of the groove - the median groove of the tongue.
