General Flashcards
Fibromuscular and glandular organ shaled like an inverted cone surrounding the prosthetic urethra
Prostate gland
To what structure is the fibrous sheath of the prostate gland attached to?
What attaches it?
Posterior aspect of the pubic bones.
Pubopeostatic ligaments
Lie on wither side of the midline of the prostate gland and are condensations of pelvic fascia
Puboprostatic ligaments
What pierces the upper parts of the posterior surface of the prostate gland?
Ejaculatory ducts (2)
The ejaculatory ducts open into the prostatic urethra at the ____________ margins of the prostatic utricle.
Lateral
What are the parts of the prostate gland?
Base
Apex
The base of the PG lies superiorly against what structure?
Neck of urinary bladder
The apex of the PG lies inferiorly against what structure?
Urogenital diaphragm
Superior relations of the PG
Base: continuous with the neck of the urinary bladder
Urethra enters center of the base of the prostate
Inferior relations of the PG
Apex lies on the upper surface of the urogenital diaphragm
Urethra leaves the prostate just above the apex kf the anterior surface
Anterior relations of the PG
Symphysis pubis
Separated by extraperitoneal fat in the retropubic space
Other name for the retropubic space
Cave of retzius
Posterior relations of the PG
Anterior surface of the rectal ampulla
Separated by the rectovesical septum
Other name for the rectovesical septum
fascia of Denonvillier
Lateral relations of the PG
Anterior fibers of the levator ani
Part of the PG that is palpated during DRE
Posterior part of PG
Lobes of the PG
- Anterior
- Median/Middle
- Posterior
- Lateral Left
- Lateral Right
Lobe of the PG which lies in front of urethra and is devoid of glandular tissue
Anterior lobe
Lobe of PG which is situated bet urethra and ejaculatory ducts. It’s upper part is related to the trigone of the bladder and is rich in glands.
Median/Middle lobe
Lobe of the PG which is situated behind the urethra and below the ejaculatory ducts. It contains glandular tissue.
Posterior lobe
Lobe of PG that lie on either side of the urethra and is separated by a shallow vertical groove on the posterior surface of the prostate. It contains many glands.
Lateral left and right lobes
Secretion of the prostate gland
Thin, milky fluid containing citric acid and acid phosphatase
For what is the secretion of the prostate gland?
Its alkaline secretion is for neutralizing the acidity in the vagina.
Two lobulated organs which consist of much-coiled tube embedded in CT.
Its upper ends are widely separated and the lower ends are close together.
Seminal vesicles
Medial relation of the seminal vesicles
Vas deferens
Anterior relation of the seminal vesicles
Urinary bladder
Posterior relation of the seminal vesicles
Rectum
Inferior end of the seminal vesicles narrows to join what structure? These structures, together, make up what structure?
Vas deferens
Ejaculatory ducts
What is the function of the secretion of seminal vesicles?
Nourishment of spermatozoa
Added to the seminal fluid
Formed by union of the vas deferens and the duct of the seminal vesicle.
Ejaculatory ducts
The ejaculatory ducts pierce the _________ surface of the prostate and open into the ____________, close to the margins of the prostatic utricle.
Posterior
Prostatic part of the urethra
What is the function of the ejaculatory ducts?
Drain seminal vesicle fluid into the prostatic urethra
A thick-walled tube about 45cm long.
Vas deferens
Forms the ejaculatory duct together with the ducts of the seminal vesicle.
Vas deferens
Trace the course of the vas deferens.
The vas deferens arises from the ______ end of the ____________.
It then passes ____________ through the ___________.
It emerges from the _________ and passes around the _______ margin of the ___________.
(This indicates what type of hernia?)
It then passes ___________ & _____________ on the ________ wall of the pelvis and crosses the _______ in the region of the ___________.
It runs _________ & ___________ on the __________ surface of the bladder, where it ends on the _________ of the VD.
Lower; tail of the epididymis
Superiorly; inguinal canal
Deep inguinal ring; lateral; inferior epigastric artery
Downward and backward; lateral; ureter; ischial spine
Medially and downward; posterior; ampulla
What is the function of the vas deferens?
Convey mature sperm from the epididymis to the ejaculatory duct and urethra.
Covering of the PG
Loose connective tissue
Length of prostate gland
3cm long
