Prostate Gland and Seminal Vesicles

vas deferens

one of two muscular tubes, each joining with its corresponding seminal vesicle to form an ejaculatory duct

seminal vesicles

The secretion of the _______ constitutes about 60% of the volume of semen

fructose

The seminal vesicles secrete a viscous fluid rich in ______

peripheral zone

The largest of the four zones that make up the posterior glandular portion of the prostate. Occupies the area lateral and posterior to the distal urethra

central zone

one of four zones of the glandular prostate; accounts for about 20% of the gland. Located at the superior edge bordering the bladder and seminal vesicles. The ejaculatory ducts course through this zone

periurethral glandular zone

one of fours zones of the glandular prostate. Consists of the this sue that lines the proximal prostatic urethra

ejaculatory ducts

two ducts that course through the prostate gland and empty into the prostatic urethra

hyperechoic

In the normal prostate, the central zone and the transition zone cannot be individually distinguished, whereas the peripheral zone may appear ______ and homogeneous in comparison

levator ani, obturator internus

The _____ and _____muscles support the prostate gland laterally

glandular

The ______ region is posterior and the largest portion of the prostate gland. Includes 4 zones

peripheral

The _______ zone occupies the posterior and lateral portions of the gland

prostatic urethra

The anterior fibromuscular stroma is located anterior to the ______ and is generally of less clinical significance because most pathology occurs in the glandular area

anterior

The fibromuscular region is located ______ to the prostatic urethra

alkaline

The prostate gland and seminal vesicles secrete _____ fluids that contribute to sperm viability

Denonvillier's fascia

a two layered fascia separating the prostate gland from the rectum

verumontanum

an area close to the center of the prostate; near the area where the ejaculatory ducts join the prostatic urethra

fibromuscular region

anterior and smallest portion of the prostate gland; located anterior to the prostatic urethra

semen

fluid that contains sperm and secretions of the glands associated with the male urogenital tract

prostate gland

gland surrounding the neck of the urinary bladder and male urethra. Supplies a secretion to semen

transition zone

one of the four zones of the prostate gland; accounts for only about 5% of glandular prostate. Has two lobes situated on the lateral aspects of the proximal prostatic urethra superior to the verumontanum. This zone borders the central zone posteriorly and laterally and the fibromuscular tissue anteriorly

seminal vesicles

paired glands at the base of the urinary bladder that are connected to the prostate gland. They empty into the distal portion of the vas deferens to form the ejaculatory ducts. They are convoluted pouch like structures that secrete an alkaline, viscous fluid rich in fructose, which contributes to sperm viability

prostatic urethra

portion of the male urethra surrounding by the prostate gland; it is adjacent to the urinary bladder
