Q

The vaginal artery is a homologue of what artery in men?

A

25
Go through the layers of the abdominal wall?
Skin 🡪 Camper’s fascia (Fatty) 🡪 Scarpa’s Fascia (Membranous) 🡪 External Oblique 🡪 Internal oblique 🡪 Transversus abdominis 🡪 Transversalis Fascia 🡪 Parietal peritoneum
26
What structure runs along the midline of the rectus abdominis?
Linea Alba
27
Why is the Linea alba often used surgically to access the abdomen via a midline laparotomy?
It is avascular
28
What are the two attachment sites of the inguinal ligament?
ASIS + Pubic Tubercle
29
How is the inguinal ligament related to the external oblique?
The inguinal ligament is the free edge of the external oblique.
30
What structure pulls the testes down creating the layers of the scrotum (from the abdominal layers) as it does so?
Gubernaculum
31
The External oblique muscle corresponds to which layer of the scrotum?
External spermatic fascia
32
The Internal oblique muscle corresponds to which layer of the scrotum?
Cremasteric muscle
33
The parietal peritoneum corresponds to which layer of the scrotum?
Tunica vaginalis
34
What two conditions can arise from a patent processus vaginalis?
1) Hydrocele 2) Indirect inguinal hernia
35
Where would you go to palpate the deep inguinal ring?
Mid-point of the inguinal ligament
36
What blood vessels is used clinically to demarcate an indirect from a direct inguinal hernia?
Inferior epigastric vessels (Indirect inguinal hernia is lateral to inferior epigastric artery, direct is medial to the vessels)
37
What two muscles in the scrotum work to elevate the testes?
1) Dartos muscle 2) Cremasteric muscle
38
What is the difference between the Dartos and Cremasteric muscles?
Dartos is under autonomic control (in cold environments it contracts to wrinkle the scrotum). Cremasteric is under conscious control.
39
What is the afferent and efferent limb of the cremasteric reflex?
Afferent – Ilioinguinal nerve. Efferent – Genital branch of the Genitofemoral Nerve
40
What is the functional unit of the testes?
Seminiferous tubules
41
What cells in the seminiferous tubules assist with spermatogenesis?
Sertoli cells
42
What hormone stimulates the Leydig cells?
LH. (LH -> Leydig cells)
43
In response to LH what do the Leydig cells produce?
Androgens e.g. testosterone
44
What does the epididymis continue as?
Vas/Ductus Deferens
45
What two structures join together on the posterior side of the bladder to make the ejaculatory duct?
Ductus Deferens + Seminal Vesicle
46
Which part of the prostate does the ejaculatory duct open into?
Prostatic urethra
47
Which zone of the prostate is most commonly affected in prostate cancer?
Peripheral
48
Which zone of the prostate is most commonly affected in Benign Prostatic Hypertrophy?
Transitional
49
The ejaculatory duct opens up in the prostatic urethra but which specific part of the prostatic urethra does it open up into?
Seminal colliculus
50
What is the function of the bulbourethral glands?
Lubrication of the urethra and production of pre-ejaculate
51
What are the 4 parts of the male urethra?
Preprostatic, prostatic, membranous, spongy
52
Which part of the penis is most susceptible to trauma when catheterising?
Membranous – due to the sharp change in angle
53
The attached end of the penis is called the root. What 3 structures make up the root of the penis?
1 Bulb and 2 Crura (Crus singular)
54
The bulb of the penis continues as what structure?
Corpus Spongiosum
55
What does the crus of the penis continue as?
Corpus cavernosa
56
What travels within the corpus spongiosum?
Urethra
57
What muscle covers the crus and helps to maintain an erection by prevention blood from leaving the penis when it contracts?
Ischiocavernosus
58
Describe the course of the pudendal nerve?
Leaves the pelvic cavity via the greater sciatic foramen 🡪 wraps around the ischial spine 🡪 re-enters the pelvic cavity via the lesser sciatic foramen
59
What is the sympathetic innervation of the pelvis?
Sacral Splanchnic nerve
60
What is the parasympathetic innervation of the pelvis?
Pelvic splanchnic nerve (Pelvic – Parasympathetic. The only parasympathetic splanchnic nerve)
61
What nerve supplies the cremasteric muscle?
Genital branch of the genitofemoral nerve
