Stereological study of the elastic fiber and smooth muscle cell system in the bovine and buffalo penis

摘要: ABSTRACT.- Ribeiro I.C.A., Abidu-Figueiredo M., Costa F.B., Pereira-Sampaio M.A. & Chagas 2013. Stereological study of the elastic fiber and smooth muscle cell system in bovine buffalo penis. Pesquisa Veterinaria Brasileira 33(Supl.1):107-112.

E-mail: chagas.m@gmail.comSamples ten penises Mediterranean buffaloes Red Sindhi cattle were used. The thickness tunica albuginea (TA), distribution cells (SMC) volume density (Vv) fibers TA, corpus cavernosum (CC) spongiosum (CS) evaluated. Vv bo-vine penis was respectively 4.07% ±0.88% 3.36% ±1.21% TA; 17.32% ±2.21% 13.14% ±1.27% (CC), 26.58% ±4.31% 31.36% ±3.67% (CS). CC presen-ted higher than bovine, while CS smaller cattle. TA showed a significant difference among species studied. arrangement SMC water suggests that this pattern is common to animals have fibroelastic penises.
