Abstract
Surgical techniques were used to isolate the extrinsic bellies of the styloglossus and hyoglossus muscles from the body of the tongue for ch olera toxin HRP injection. An average of 53 styloglossus and 121 hyogl ossus motoneurons in the dorsal subdivision of the hypoglossal nucleus were demonstrated using tetramethyl benzidine histochemistry. Stylogl ossus motoneurons were restricted to the rostral 25% of the nucleus wh ile hyoglossus motoneurons occupied other regions of the dorsal nucleu s.
