Las vesículas seminales son un par de glándulas tubulares, alargadas y muy tortuosas, ubicadas en la pared posterior de la vejiga urinaria paralela a la ampolla de los conductos deferentes. Un conducto excretor corto que parte de cada vesícula seminal se combina con la ampolla del conducto deferente para formar el conducto eyaculador. Histology. Histologically, the seminal vesicles are defined by their tortuous pathways, false lumens, pseudo-stratified columnar epithelium and cuboidal cells along the basal layer.

Vesicula seminalis histology

They ultimately provide around 70% of the total volume of semen. The seminal vesicle (SV) and vas deferens (VD) are ancillary but essential urogenital organs. Understanding their embryologic features and anatomy can be helpful in evaluating various disorders of these organs. Recently, cross-sectional imaging modalities, including ultrasonography, computed tomography, and magnetic resonance (MR) imaging, have been increasingly used for evaluation of the SV and VD. Shotgun Histology Seminal Vesicles Histology Histologically, the seminal vesicles are defined by their tortuous pathways, false lumens, pseudo-stratified columnar epithelium and cuboidal cells along the basal layer. The height of these columnar cells, and therefore activity, is dependent upon testosterone levels in the blood.

Reproductive system consist of two testes, in which different stages of spermatogenesis are observed, two tubular vas deferens, two vesicula seminalis, accessory A-E: abscess adenocarcinoma adenosis / atypical adenomatous hyperplasia adenosquamous carcinoma amyloid anatomy & histology atrophic adenocarcinoma atrophy atypical glands, suspicious for malignancy basal cell carcinoma basal cell hyperplasia benign prostatic hyperplasia biopsy blue nevus calculi carcinoma of seminal vesicle clear cell Two vesicula seminalis unite to connect with the ejaculatory ducts where two parameres (p) are segmented. The two mesomeres comprising ejaculatory ducts fuse to form the aedeagus (e). The distal end of the aedeagus is invaginated and connected with the gonophore (g). That part of gonophore is called phallotreme (pt). Using light and scanning electron microscopy, histology an d morphology of the male reproductive system of Coreus marginatus (Linnaeus, 1758) are identified and described.

The seminal vesicle is most easily identified by its central lumen that has been partitioned by the arcading of its mucosal folds. Smooth muscle surrounds the seminal vesicle. 40x.

De cada glándula parte un conducto excretor corto, los cuales se combinan con la ampolla del conducto deferente para formar el conducto eyaculador. Tumörfynd i omgivande strukturer (vesicula seminalis, blåshalsmuskulatur). Det finns data som indikerar att prognosen vid prostatacancer försämras vid samtidig förekomst av intraduktal cancer (IDC). Man kan därför överväga att rapportera sådana fynd även i prostatektomipreparat. Imaging Traditionally, the seminal vesicles were evaluated with seminal vesiculography.
