Chapter 17 Flashcards
Porstate anteriot relationship
Symphysis pubis
Pubic arch
Superior to prostate is
Seminal vesicles and bladder
Path of how semen is transported to outside
Epididymis Vas deferens Join seminal vesicles Ejaculatory ducts Urethra
Seminal vesicles
2 hollow, sacculated structures
Base bladder
Superior to prostate gland
Inferior to vas deferens and ureters
Prostate size and shape
Chestnut shape and size
Base of prostate is
Most superior part
Apex is
Most inferior part `
Ejaculatory ducts join urehtrea approx
Mid way through the prostate
Prostatic urethral divided into
Proximal and distal
Ducts
Transport seminal fluid
Seminal vesicles adds
Secretions to seminal fluid
Prostate adds
Secretions to seminal fluid
Urethra
Conduit for semen and urine
Prostaticovesical arteries come from
Internal illiac artery —> prostatic and inferior vesical artery
Inferior vesical artery supplies
The base of the bladder, seminal vesicles and ureter
Prostatic artery branches to
Capsular and urethral arteries
Supply prostate
Venous supply of prostate form
A network around the sides and base of prostate- deep dorsal penile vein draining into the internal iliac veins
2 regions of prostate gland
Fibromuscular region/stroma
Glandular regio
Fibromuscular region/stoma
Smaller sction
Anterior to the prostatic urethra
Less clinical significance
Glandular region
Posterior portion
Glandular region consists of what 4 zones
Peripheral
Central
Transition zone
Periurethral glandular tissue/zone
These zones have differing embryologic origins and susceptibilities to disease
Peripheral zone
Largest ~ 70% of glandular tissue
70% of cancers found here
posterior, lateral and apical regions of the prostate
Resembles “eggcup” holding the egg of the central gland
Central zone
25% of prostatic glandular tissue
5% of cancer located in Central Zone
Vas deferens and seminal vesicles
-enter at Central zone
Transitional zone
lateral aspects of the proximal prostatic urethra
~ 5% of glandular tissue
20 % of cancers
Second most common spot for cancers
