Skin
Camper (Superficial fatty), Scarpa (Deep Membranous),
Gallaudet (External oblique fascia)
Internal Oblique fascia
Transversus abdominis
Transversalis fascia
Properitoneal space and fat
Parietal peritoneum

4

SkIn
Dartos
Colles
External spermatic fascia
Cremasteric fascia
Does not reach the scrotum
Internal spermatic fascia
Properitoneal space and fat
Tunica vaginalis

5

The superficial fatty layer is the ____ muscle of the scrotum

Superficial fatty (camper) : dartos

6

The colles fascia is equivalent to the _____ in the abdominal wall

Scarpas

Deep Membranous (scarpa) : Colles

7

Gallaudet fascia is also the ____ in the scrotum

external spermatic fascia

8

The tunica vaginalis is equivalent of ___ in the abdomen

parietal peritoneum

9

This layer of the abdominal wall does not reach the scrotum

transversus abdominis

10

This is equivalent of the transversalis fascia in the in the internal spermatic fascia

transversalis fascia

11

What is the length of the inguinal canal?

4-6 cm in length

12

What are the walls of the inguinal canal?

Anterior: External oblique aponeurosis

Posterior: Medial - Conjoint, Lateral - transversalis fascia and TA muscle

Lateral: Internal oblique

Medial: Conjoint tendon

Superior: arching fibers of IO and TA muscles

Inferior: Inguinal and lacunal ligamnet

13

This lies immediately above and medial to the pubic tubercle; triangular opening

superficial inguinal ring

14

located between the pubic tubercle and the anterior superior iliac spine

deep inguinal ring

15

Contents of the femoral sheath

1. Femoral artery
2. Femoral vein
3. Lymphatics

16

The inguinal ligament is also called

Poupart's ligament

17

the conjoint tendon is composed of _____

Internal Oblique
Transversus Abdominis

18

[true/false]

the spermatic cord passes through the inguinal canal

true

19

What are the contents of the spermatic cord?

3 fasciae: external, cremasteric, internal spermatic fascia
3 arteries: testicular, cremasteric, vas deferens
3 veins: pampiniform, cremasteric, deferential
3 nerve: autonomic, genital branch of genitofemoral nerve, ilioinguinal nerve
Vas deferens
Lymphatics

20

the lacunar ligament under the inguinal ligament is called

Giembernat's

21

the nerve inside the triangle of doom

Genital branch of genitofemoral nerve

22

the arteries and veinsinside the triangle of doom

iliac artery and vein
gonadal vessels

23

the medial border of the triangle of doom is

ductus deferens

24

What are the borders of the triangle of pain

Inferolateral: iliopubic
Lateral: peritoneum
Superomedial: gonadal vessels

25

What are the arteries and veins containing the triangle of pain

deep circumflex iliac artery and vein

26

What are the nerve inside the triangle of pain

Femoral nerve
Femoral branch of the genitofemoral nerve
anterior cutaneous nerve
lateral femoral cutaneous nerve

27

the circle of death is composed of these arteries

1. External iliac arteries (from common iliac)
2. Internal iliac arteries (from common iliac)
3. obturator artery
4. Aberrant artery
5. Inferior epigastric

28

[sphincter/shutter action]

Tranversalis fascia

sphincter action

29

[sphincter/shutter action]

Transversus abdominis and internal oblique muscles

shutter action

30

This forms a sling that closes the internal ring under the muscular edge of the internal oblique muscle by contraction fo the transversus abdominis muscle. This acts as a sphincter.

transversalis fascia
