title: Topographical representation of masticatory muscles in the motor trigeminal nucleus in the rabbit: A HRP study.
abstract: Myotopical localization of masticatory motoneurons was studied in rabbit by means of the horseradish peroxidase (HRP) method. As described by Meessen and Olszewsky [6], the motor trigeminal nucleus of rabbit is divided into 3 divisions; caudoventromedially alpha, rostroventromedially beta and dorsolaterally gamma nuclei. Within the alpha nucleus, the anterior digastric motoneurons are located ventromedially and the mylohyoid motoneurons dorsolaterally. Lateral pterygoid motoneurons are situated in the beta nucleus. Within the gamma nucleus, the temporal, masseter and medial pterygoid muscles are represented medially, centrally and ventrolaterally, respectively.
