Select the INCORRECT statement.

Concerning the epididymis…

it has a head, body and tail

sperm are stored for up to several months in it

sperm are mature upon entering it

it takes 20 days for sperm to move along its length

Select the INCORRECT answer.

The duct of the epididymis…

connects the rete testis with the vas deferens

is lined with germinal epithelium

occupies the body and tail of the epididymis

contains smooth muscle in the wall

is lined with germinal epithelium

Select the INCORRECT statement.

Concerning the pelvic diaphragm…

it is composed in part by coccygeus

it is composed in part by levator ani

it supports the pelvic viscera

it does not contribute to faecal continence

Select the INCORRECT statement.

The prostate…

is seperated from the rectum by a fascial septum.

is pierced by the ducts of the seminal vesicles.

possesses lateral and median lobes

has a rich venous plexus associated with its fascial sheath.

is pierced by the ducts of the seminal vesicles.

(Each duct of the seminal vesicle joins the vas deferens to form the ejaculatory duct, just prior to entering the prostate.)

Select the most appropriate answer. Concerning the prostate:

is the size of an orange

surrounds the membranous urethra

has no function in man

has a stony hard constistency

none of the above

None of the above

Select the correct answer.

The seminal vesicles…

store spermatozoa

are surrounded by the corpora cavernosa

have smooth muscle in their walls

empty into the prostatic urethra

secretion has a role in the activation of sperm

have smooth muscle in their walls

Select the correct answer.

The seminal vesicles…

consist of many coiled tubes

lie medial to their corresponding vas deferens

lie against the lateral surface of the bladder

are palpable by digital rectal examination when enlarged

The spermatic cord contains all the following, EXCEPT

vas deferens

ejaculatory duct

pampiniform plexus

cremaster muscle

testicular artery

ejaculatory duct

The spermatic cord has three fascial coverings (spermatic fascia) derived from the anterior abdominal wall. Name the correct order of these coverings from external (superficial) to internal (deep)?

external oblique, transversus abdominis/internal oblique, transversalis fascia

(The layers are known as the external spermatic, cremaster and internal spermatic fascias.)

A 22 year old man is suspected as having a testicular tumour, having found a lump upon self-examination. Should this tumour be malignant, to which nodes would the tumour metastasize initially?

Paraaortic nodes

Select the CORRECT statement. Concerning the testis... they descend from the anterior abdominal wall the are intraperitoneal before they descend share lymphatic drainage with the scrotum can be drawn superiorly in the cremaster reflex

can be drawn superiorly in the cremaster reflex (They descend behind the peritoneum. The correct answer is that they can be drawn superiorly by the cremasteric reflex.)

Select the INCORRECT statement. Concerning the testis: the testicular veins form the pampiniform plexus which helps regulate testicular temperature has lymphatic drainage into the para-aortic nodes the left testicular vein drain into the inferior vena cava the right testicular vein drain into the inferior vena cava the testicular arteries arise from the aorta

The left testicular vein drains into the inferior vena cava (drains into left renal vein)

Select the INCORRECT statement. Concerning the penis: the deep dorsal vein drains to the prostatic venous plexus the corpus spongiosum contains the spongy urethra the dorsal artery supplies the tissue of the corpora cavernosa the crura are attached to the ischiopubic ramus the narrowest part of the urethra is in the penis

the dorsal artery supplies the tissue of the corpora cavernosa (It is the deep arteries and not the dorsal arteries of the penis which supply the corpora cavernosa.)

Select the correct answer. The penis... comprises two cylinders of erectile tissue contains the corpora cavernosa which expands posteriorly to form the bulb of the penis has a lymph drainage to the external iliac nodes contains the ventral corpus spongiosum which expands to form the glans penis

contains the ventral corpus spongiosum which expands to form the glans penis (The corpus spongiosum is on the ventral side of the penis (dorsal and ventral surfaces of are named when the penis is in the erect position).)

Which structure can be felt as a firm, hard cord on the posterior aspect of the spermatic cord as it traverses the scrotum to the superfical inguinal ring?

Vas deferens/ ductus deferens

Select the correct statement. Each vas deferens... ends by opening into the prostatic urethra lies lateral to their corresponding seminal vesicle is a continuation of the canal of the epididymis stores sperm

is a continuation of the canal of the epididymis

The lymphatic drainage of both the vas deferens and seminal vesicles is to the internal and external iliac nodes. True or false?

True
