What muscle attaches between the lateral side of the root of the tongue and the hyoid bone (greater horn and body)?
hyoglossus
What is found within the carotid triangle and can be traced from the ECA medial to the hyoglossus muscle?
lingual artery
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.
mental spines
mandible and the hyoid
superficial
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.
hypoglossal nerve
Near the superior end of the hyoglossus on the lateral side of the root of the tongue identify ___.
styloglossus
What is primarily found on the dorsal body of the tongue?
lingual papillae
furrow running longitudinally along the dorsum of the body of the tongue
median sulcus
What is found on the dorsal surface of the root of the tongue? Where is this in relation to the terminal sulcus?
lingual tonsils, posterior
Between the median and lateral folds on the anterior surface of the epiglottis is the ______ _______.
