Reesha and Jasmine

1. Label the following diagram

2. Which 3 arteries are contained in the SPERMATIC CORD?

1. Testicular A.2. Ductus Deferens A.3. Cremasteric A.

3. TABOO

One of your team members come up and complete the following task:

Get your team mates to guess the word on the card we give you WITHOUT SAYING THE WORD

1. Which lymph nodes do the testes drain to?A. InguinalB.External IliacC.Para-AorticD.EpigastricE. Hypogastric

4. 2 Part question:

2. Why?

Testes develop in the abdominal cavity and descend into the scrotum during development. During descent they drag their blood supply and lymph drainage with them. Thing is relevant when considering metastatic or infective spread from the testes

5. Which structures can be felt on a PR exam?

1. Anal Canal2. Inferior Rectum3. Sacrum4. Coccyx5. Sacral Lymph Nodes6. Prostate

6. Label the following diagram

7. Which structures are difficult to pass during catheterisation?

Preprostatic

Prostatic

Bulbo-urethral gland (Cowpers)

Membranous (non distensible)

Penile

Navicular fossa

Perineal membrane

External urethral sphincter

Levator ani

8. Pictionary

One of your team members come up and complete the following task:

Get your team mates to guess the word on the card we give you BY DRAWING THEM OUT

9. Match the following

EMISSION

EJACULATION

ERECTION

SOMATIC

SYMPATHETIC

PARASYMPATHETIC

10. Define PRIAPISM

A.Permanently stimulated erection, which

continues >4 hrs after ejactulation

B.Non-stimulated persistent painful erection, which

lasts >4 hrs

C.Erection unable to be maintained due to pain

D.Persistent painful erection lasting >6 hrs

E. Persistently flaccid penis

11. Name the 3 layers which make up the scrotal sac?

1. Internal spermatic fascia2. Cremasteric fascia3. External spermatic fascia

12. Label the following diagram

13. EEEKKKKK!!!

Using your anatomical knowledge to explain how a perineal infection can spread to the lower abdominal wall?

14. Taboo

One of your team members come up and complete the following task:

Get your team mates to guess the word on the card we give you WITHOUT SAYING THE WORD

15. How does your erection work?

PARASYMATHETIC innervation is responsible for your hard on.

Do you know which route parasympathetic stimulation arrives at your penis?

Take these cards, select the right components and put them in the right order.

This is important to know during COLORECTAL or PROSTATIC surgery as damage can occur anywhere along this route and lead to pretty flaccid consequences :/

16. Answer the following questions…

1. Which nerve provides SOMATIC innervation to the penis?

3. Where can this N. be anaesthetised?

2. Describe its route (3)

PUDENDAL

• Travels inferior to pelvic floor• Via deep perineal pouch• Through pudendal canal

a. ISCHIAL SPINE -> unilateral anaesthesiab. MIDLINE SUSPENSORY LIGAMENT -> bilateral

anaesthesia

4 left to do

Processus vaginalis and weak spot for indirect hernias

Prostate venous drainage -> metastatic spread to vertebral bodies

2 muscles for erection and ejaculation Structure of Blood supply and venous drainage

to penis + how they are involved in maintaining an erection Helicine arteries Arterio-venous anatamoses Venous plexus
