What is found within the carotid triangle and can be traced from the ECA medial to the hyoglossus muscle?
Genioglossus attaches anteriorly to the ____ _____ and then merges into the tongue, while geniohyoid is between the ____ and the _____. The mylohyoid is the most (superficial/deep) of these three.
mandible and the hyoid
Near the 3rd mandibular molar tooth we will identify the _______ ganglion suspended below the ____ nerve.
submandibular ganglion suspended below the lingual nerve
What other nerve will we trace to the sublingual region? It passes between the deep part of the submandibular gland and the hyoglossus muscle.
Near the superior end of the hyoglossus on the lateral side of the root of the tongue identify ___.
What is primarily found on the dorsal body of the tongue?
furrow running longitudinally along the dorsum of the body of the tongue
What is found on the dorsal surface of the root of the tongue? Where is this in relation to the terminal sulcus?
