The whole morphology of the intrinsic laryngeal muscle and innervations of the cranial laryngeal nerve and recurrent laryngeal nerve of CS22 stage in Rhinolophus malayanus and E18.5 stage in Mus musculus. A Dorsal view of the hyolaryngeal cartilages, intrinsic laryngeal muscles, and vagus nerve of CS22 fetus of R. malayanus. B Lateral view of the hyolaryngeal cartilages, intrinsic laryngeal muscles, and vagus nerve of CS 22 fetus of R. malayanus. C Dorsal view of the intrinsic laryngeal muscles and vagus nerve of CS22 fetus of R. malayanus. D Lateral view of the intrinsic laryngeal muscles and vagus nerve of CS22 fetus of R. malayanus. E Dorsal view of the hyolaryngeal cartilages, intrinsic laryngeal muscles, cranial laryngeal nerve, and recurrent laryngeal nerve of E18.5 fetus of M. musculus. F Lateral view of the hyolaryngeal cartilages, intrinsic laryngeal muscles, cranial laryngeal nerve, and recurrent laryngeal nerve of E18.5 fetus of M. musculus. G Dorsal view of the intrinsic laryngeal muscles, cranial laryngeal nerve, and recurrent laryngeal nerve of E18.5 fetus of M. musculus. H Lateral view of the intrinsic laryngeal muscles, cranial laryngeal nerve, and recurrent laryngeal nerve of E18.5 fetus of M. musculus. The cranial laryngeal nerve and recurrent laryngeal nerve were visualized using the immunohistochemistry of the acetylated tubulin antibody. The left side of the hyolaryngeal morphology is shown in lateral view. See text for abbreviations
