Evidence for the anatomical origins of hypoglossal afferents in the tongue of the leopard frog, Rana pipiens.
In this study, the origins of sensory neurons from the tongue that ascend in the hypoglossal nerve were identified and described in the leopard frog, Rana pipiens. Previous studies have shown that these afferents are used to coordinate the timing of jaw and tongue muscles, and are important in the motor control of feeding. These sensory neurons innervate the tongue bilaterally and appear to originate in the dorsal fungiform papillae of the tongue epithelium.
