TL;DR: Despite the importance of the rabbit (Oryctolagus cuniculus) in reproductive research, no comprehensive account of the anatomical organization of the female reproductive tract is presently available.
Abstract: Background: Despite the importance of the rabbit (Orycto- lagus cuniculus) in reproductive research, no comprehensive account of the anatomical organization of the female reproductive tract is presently available. Methods: Based on gross dissection and on the electrical stimulation of striated muscles in 10 domestic female rabbits, it was the aim of this study to help fill this gap by describing the origin, insertion, and general action of muscles associated with the vaginal tract and with associated scent glands. Results: Compared with the better-studied rat or cat, the long vaginal tract of the rabbit is characterized by a well-developed and complex musculature. The bulbospongiosus, ischiocavernosus, constrictor ves- tibuli, and constrictor vulvae muscles, poorly developed or absent in the female rat or cat, were particularly conspicuous. Scent glands, including the newly identified preputial glands, were also a distinctive feature. Conclusion: These structures may represent specializations underlying the rapid copulation, rapid parturition, and well-developed chemical communication characteristic of the reproductive efficiency of the rabbit.

TL;DR: Muscles of the perineal region were dissected in 20 cats and pars cranialis of external anal sphincter gave origin to theconstrictor vestibuli muscle, and pars caudalis to constrictor vulvae muscle.
Abstract: Muscles of the perineal region were dissected in 20 cats. Levator ani muscle was composed of two parts: iliocaudalis and puboischiocaudalis; both parts inserted entirely on caudal vertebrae, as did the coccygeus muscle. A well developed band of smooth muscle, the pars analis of retractor penis (clitoridis), inserted on the anal canal to retract the anus. The external anal sphincter had pars caudalis and pars cranialis divisions, the latter covered paired anal sacs. In addition, a distinct sphincter encircled each anal sac duct. In the male, levator scroti muscle originated from external anal sphincter. There was no continuity between external anal sphincter and bulbospongiosus muscles. Cremaster muscles were absent in the cat. In the female, pars cranialis of external anal sphincter gave origin to the constrictor vestibuli muscle, and pars caudalis to constrictor vulvae muscle. Bulboglandularis muscles were present in both sexes. Urethralis, ischiourethralis, and ischiocavernosus muscles in the cat were similar to other quadripeds.
