Q

How many sacral bones are there and at what age do they fuse to become one bone? Are there any variations?

A

5 - age 16-18

Sometimes 4-6 vertebrae, also sexually dimorphic - females have wider and shorter sacral bones

Q

What is the main difference between the male and female pelvis?

A

The male superior aperture is heart shaped with maximum width close to the sacrum, whereas in females the superior aperture is more rounded and the maximum width is further in front of the sacrum

Q

What are the contents of the spermatic cord?

A

Think FOAN:
3 fascial layers - external spermatic, cremasteric, internal spermatic fascia

3 other structures - pampiniform plexus, vas deferens, testicular lymphatics

3 arteries - deferential, testicular, cremasteric

3 nerves - genital branch of genitofemoral nerve, autonomic and visceral afferent fibres
(N.B. ilioinguinal nerve is not in the spermatic cord but runs next to it)

Q

What problems may arise from a ‘back street’ abortion?

A

Perforation of the uterus
Bleeding
Infection of the peritoneal cavity

18
Q

What are the two surrounding pouches in relation to the uterus called?

A

Anterior to uterus- uterovesical pouch

Posterior to uterus - rectouterine pouch (of Douglas)

19
Q

Define antiflexion

A

Body of uterus is bent forward on the cervix

20
Q

Define antiversion

A

The uterus is bend forwards at a 90 degree angle to the vagina

21
Q

How do spermatogonia divide?

A

By mitosis

22
Q

What are the names of the contractile cells which lie outside seminiferous tubules?

A

Peritubular myoid cells

23
Q

Where are Sertoli cells located?

A

On the basement membrane within seminiferous tubules

24
Q

What are Sertoli cells responsible for the formation of and why is this important?

A

The blood-testis barrier - important as it prevents autoimmune attack against the developing gametes

25
Q

How do primary spermatocytes divide?

A

1st meiotic division

26
Q

How to secondary spermatocytes divide? What do they become?

A

2nd meiotic division

Become spermatids

27
Q

Are mature spermatozoa on the luminal or basal edge of the seminiferous tubule?

A

Luminal

28
Q

Where are Leydig cells found?

A

Within interstitial tissue lying between seminiferous tubules

29
Q

What do Leydig cells produce?

A

Testosterone

30
Q

What tissue surrounds the penile urethra?

A

Corpus spongiosum

31
Q

What is the erectile tissue of the penis known as?

A

Corpus cavernosum

32
Q

What features of the corpus cavernosum allows for an erection?

A

Blood sinuses which allows for a large volume of blood to fill them, sinuses are separated by trabeculae of connective tissue and smooth muscle

33
Q

Describe the histological changes in the epithelium of the urethra from the proximal end towards the external urethral meatus

A

Pseudostratified columnar to stratified squamous urothelium

34
Q

How many layers of smooth muscle compose the wall of the ductus deferens?

A

3 layers

- middle circular, outer and inner longitudinal

35
Q

What epithelium lines the ductus deferens?

A

Pseudostratified columnar epithelium with stereocilia

36
Q

What are stereocilia?

A

Non-motile, apical modifications of the cells, distinct, but closely related to microvilli

37
Q

What is the role of the pampiniform plexus of veins draining the testicles?

A

To try and remove heat from the blood

38
Q

What is the clinical condition varicocoele?

A

Abnormal enlargement of the pampiniform plexus in the scrotum

39
Q

What sort of tissue forms the stroma of the prostate?

A

Fibromuscular tissue

40
Q

What clinical condition is associated with the stroma of the prostate?

A

Benign prostatic hyperplasia

41
Q

The prostatic secretion is produced by the cuboidal/low columnar epithelial cells. Do you know any clinical conditions with which they are associated?

A

Prostatitis

42
Q

In some of the secretory units of the prostate are amyloid bodies, which are eosinophilic bodies. What do they represent?

A

Inspissated (coagulated) secretion
