Fig. 2From: Botulinum toxin A injection into the anterior belly of the digastric muscle increased the posterior width of the maxillary arch in developing ratsAnthropometric measurements in the maxillofacial bone of rats. (1) Ramus height I: distance between the Cd and Gn. (2) Ramus height II: distance between the Co and Gn. (3) Ramus height III: distance between the Co and antegonial notch. (4) Corpus height: distance between the mandibular alveolar point and Me. (5) Mandibular plane angle I: angle between the line of Cd-Gn and Gn-Me. (6) Mandibular plane angle II: angle between the line of Go-Gn and Gn-Me. (7) Total mandibular length: distance between the Cd and infradentale. (8) Corpus length: distance between the Go and infradentale. (9) Zygomatic arch width: distance between the bilateral Zy. (10) Maxillary point (key ridge) width: distance between the bilateral key ridge point. (11) Mandibular molar width: distance between the bilateral mesiobuccal cusps of the mandibular first molars.
