The seminal vesicles (also called vesicular glands [1] or seminal glands) are a pair of convoluted tubular accessory glands that lie behind the urinary bladder of male mammals. They secrete fluid that largely composes the semen. The vesicles are 5–10 cm in size, 3–5 cm in diameter, and are located between the bladder and the rectum.
A histopathologic diagnosis of prostate cancer is the discernment of whether there is a cancer in the prostate, as well as specifying any subdiagnosis of prostate cancer if possible. The histopathologic subdiagnosis of prostate cancer has implications for the possibility and methodology of any subsequent Gleason scoring . [ 1 ]
The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
Vessels surrounding the vas deferens, some of the vessels in the seminal vesicle, and a vessel from the posterior surface of the prostate drain into the external iliac lymph nodes. [4] Some of the seminal vesicle vessels, prostatic vessels, and vessels from the anterior prostate drain into internal iliac lymph nodes. [4]
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus. [3]
radical prostatectomy - complete removal of prostate and seminal vesicles (a treatment for prostate cancer). Blood tests for prostate specific antigen (PSA), digital rectal examination , ultrasound scanning of the prostate via the rectum , fine needle aspiration or medical imaging studies (such as magnetic resonance imaging ) are not useful for ...
Pattern 1 - The cancerous prostate closely resembles normal prostate tissue. The glands are small, well-formed, and closely packed. This corresponds to a well differentiated carcinoma. Pattern 2 - The tissue still has well-formed glands, but they are larger and have more tissue between them, implying that the stroma has increased. This also ...
Prostasomes are extracellular vesicles (40-500 nm in diameter) secreted by the prostate gland epithelial cells into seminal fluid. [1] They possess an unusual lipid composition and a tight and highly ordered structure of their lipid bilayer membrane, resembling that of lipid raft domains. Prostasomes appear to improve sperm motility and protect ...
