“…However, in rats, carnivores and primates, these neurons are located in the dorsomedial nucleus of the ventral horn of the SC lumbo-sacral segments (Dekker et al, 1973;Konishi et al, 1978;Sato et al, 1978;Yamamoto et al, 1978;Breedlove and Arnold, 1980;Nakagawa, 1980;Kuzuhara et al, 1980;Schrøder, 1980Schrøder, , 1981Breedlove et al, 1983;Roppolo et al, 1985;Katagiri et al, 1986;McKenna and Nadelhaft, 1986;Holstege and Tan, 1987;Peshori et al, 1995;Marson and Carson, 1999;Tang et al, 1999;Verroneau-Longueville et al, 1999;Holstege, 2005).…”

“…The BSM originates from the tunica albuginea lateral to the penis corpus spongiosum and terminates on the median septum of the perineum (Schaller, 1992), and it is innervated by the pudendal nerve as it has already been demonstrated in the cat (Martin et al, 1974;Yamamoto et al, 1978;Ueyama et al, 1984;Holstege and Tan, 1987), in the rat (Schrøder, 1980;Katagiri et al, 1986;Mc Kenna and Nadelhaft, 1986), in the monkey (Roppolo et al, 1985), and in the human foetouses (Yucel and Baskin, 2003).…”

The location, number, and size of the neurons innervating the bulbospongiosus muscle (BSM) were studied in male pigs, by means of Fast Blue (FB) retrograde transport. After injection of FB into the left BSM, labeled neurons were found bilaterally in the L2-S4 sympathetic trunk ganglia (STGs), in the caudal mesenteric ganglia (CMGs), in the microganglia of the pelvic plexus (PGs), in a dorsolateral area with respect to the central canal of S1-S3 segments of the spinal cord (SC) and in the S1-S4 ipsilateral and S2-S3 contralateral spinal ganglia (SGs). The mean number of labeled FB cells was 3,122 AE 1,968 in STGs, 979 AE 667 in CMGs, 108 AE 104 in PGs, 89 AE 39 in SC and 77 AE 23 in SGs. The area of the multipolar neurons was 852 AE 22 lm 2 in the STGs, 878 AE 23 lm 2 in the CMGs and 922 AE 31 lm 2 in the PGs. The multipolar SC neurons had an area of 1,057 AE 38 lm 2 , while pseudounipolar SG cells had dimensions of 2,281 AE 129 lm 2 . Our research enables us to highlight two peculiarities regarding the innervation of the boar BSM: the very high number of labeled autonomic neurons and the particular localization of the motor somatic nucleus.

“…Neither were any fast conducting pelvic fibres found in S3 (Ryall & Piercey, 1970), the parasympathetic motoneurones of pelvic nerve being excluded from our sample because all of those we recorded were conducting with a-fibre conduction velocity. (iv) The locations of tail and non-pudendal motoneurones with crossed disynaptic inhibition overlapped and was more medial than that of pudendal motoneurones in S2 which were found in the same part of the ventral horn as indicated by Oliver et al (1970) and R. Mackel (personal communication) (see, however, Yamamoto et al 1978). Pudendal motoneurones appeared to be situated outside the area within which the distinct compound antidromic field potentials are evoked by stimulation of the ventral roots, and they were rather difficult to penetrate unless tracked for systematically.…”

5. In anaesthetized preparations crossed recurrent inhibition appeared, instead of the recurrent facilitation, in more than one half of the tested motoneurones.6. A comparison of the input from ipsilateral and contralateral afferents to identified motoneurones of tail muscles with the input to pudendal motoneurones led to the conclusion that crossed disynaptic inhibition is evoked specifically in tail motoneurones.7. Intracellular staining of sacral motoneurones with horseradish peroxidase revealed that the tail motoneurones and others with crossed disynaptic inhibition differ from the pudendal motoneurones in their location and in a number of morphological features; tail motoneurones are larger, they have differently directed dendrites and they show more extensively branched initial axon collaterals which appeared to ramify only within the ventral and lateral parts of the ipsilateral ventral horn.8. One Renshaw cell which was stained with horseradish peroxidase was found to project contralaterally, after giving a number of axon collaterals ipsilaterally.

“…Porém em alguns mamíferos como no gato (Martin et al1974, Yamamoto et al 1978, Ueyama et al 1984; no rato (Schröder 1980, Katagiri et al 1986, McKenna & Nadelhaft 1986) e em Humanos (Yucel & Baskin 2003), este músculo origina-se na túnica albugínea, lateral ao corpo do pênis e insere na fáscia do bulbo do pênis. Segundo Sachs (1982a;1983b) e Tang et al(1998, este músculo apresenta um envolvimento no mecanismo de ereção, respostas reϐlexas a estimulaçaõ da região genital, participando do processo urogenital e expulsão das últimas gotas da urina ou sêmen da uretra (McKenna et al 1991, Bancila et al 1999 como nos ratos e na viscacha.…”

Pesq. Vet. Bras. 32(2):183-187, fevereiro 2012 183 RESUMO.-Entre as espécies de roedores já estudadas podemos destacar a grande variação na morfologia do aparelho reprodutor masculino. Assim, considerando a importância ecológica dos roedores, e a grande representatividade numérica quanto geográϐica destes animais, bem como a escassez que aborda a anatomia reprodutiva, desenvolvemos este trabalho com um roedor histricomorfo da América do Sul, a viscacha. Este animal apresenta algumas característi-cas reprodutivas bem peculiares, desta forma descreveremos a anatomia macroscópica da musculatura perineal, e o papel dos músculos no comportamento copulatório desForma e função dos músculos perineais da viscacha (Lagostomus maximus) 1 Naira C.G. Among the rodent species studied we can highlight the wide variation in the morphology of the male reproductive system. Thus, considering the ecological importance of rodents, and the large number and geographical representation of this animal, as well as shortages regarding the reproductive anatomy, we developed this study with viscacha, a South American histricomorph rodent. As this species has some very peculiar reproductive features, we described the gross anatomy of the perineal muscles and the role of copulatory behavior. The perineal region of viscacha is composed of ϐive muscles, three of which are arranged in the superϐicial genitourinary diaphragm, as Musculus ischiocavernosus, M. bulbocavernosus and M. bulbospongiosus, and the muscles that lie at the pelvic diaphragm, M. levator ani and M. retractor penis. Therefore, we emphasize that the study of the pelvic ϐloor in wild animals is of great value, then contribute to a better understanding of the mechanisms related to erection and ejaculation or collaborate with studies on the reproduction of animals.
