VASQUEZ, Bélgica  and  DEL SOL, Mariano. MORPHOLOGIC STUDY OF THE BULBOURETHRAL GLAND OF THE RABBIT (Oryctolagus cuniculus). Rev. chil. anat. [online]. 2001, vol.19, n.2, pp.221-228. ISSN 0716-9868.

The purpose of this study was to learn about the rabbit bulbourethral gland morphology (Orictolagus cuniculus), to later proceed with their morphofunctional study. 5 rabbits specimens (Oryctolagus cuniculus) from the  Bioterio of the Medicine Faculty, Universidad de La Frontera, Chile, were chosen on their highest  reproduction period. Dissection was performed over the pelvic region with the help of a  ransor  magnifier glass. The genital apparatus was completely removed and their anatomical structures were exposed, specially   those conducts which ended at the urethra allowing the bulbourethral gland isolation. The samples were fixed in Bouin and later included in Paraplast. Serial cuts of 5 µm thick  were performed and later  stained for their histological and  histochemical study. The morphological study together at the pictures taken, were performed in a Carl Zeiss, Axiolab microscope with an MC 80 DX camera stand. Our results present the bulbourethral gland as an unique structure, surrounded by the bulboglandularis muscle and a fibrous capsule. Which in  itself has a cuboidal  form, extended in the anterior-posterior sense, with short ducts ended on the posterior wall of the urethra. The gland is related with the prostate and the paraprostate presenting much vasculararization. It presents  an alveolar type, covered by striated muscular and connective tissue, this last one is formed by elastic collagen fibers which penetrates in their interior dividing the gland in two lobules and subdividing each one of them in many smaller  lobulated forms. The histochemical study reveal the presence of glycogen grains, neutral and sulfated and non sulfated acid mucous substances. The morphological difference found at the cellular population of the rabbit  bulbourethral gland can be attributed  to the  secretory stage in which was found
