Pudendal canal, Internal pudendal A, Pudendal Nerve

Question 1

Sites of pudendal Canal

Answer 1

At the splitting of operator internal fascia lower part. Beginning at the lesser sciatic foramen

Question 2

Ending of pudendal Canal

Answer 2

Ends by opening in deep perineal pouch

Question 3

Contents of pudendal canal

Answer 3

• Internal pudendal vessels
• Pudendal Nerve

Question 4

Beginning of internal pudendal artery

Answer 4

as one of the two terminals of the anterior division of internal iliac artery

Question 5

Course of internal pudendal Artery

Answer 5

1. It leaves the pelvis through greater sciatic foreman below piriformis muscle
2. it crosses ischial spine, then pass through lesser sciatic foreman to reach ischiorectal fossa
3. it then enters pudendal Canal and runs until it reaches and enters deep perineal pouch

Question 6

End of internal pudendal artery

Answer 6

Posterior to symphysis pubis, it divides into two terminals, dorsal artery of penis and deep artery of penis 🚹 / dorsal artery of clitoris and deep artery of clitoris 🚺

Question 7

enumerate branches of internal pudendal artery

Answer 7

• inferior rectal artery
• perineal artery
• artery of bulb
• urethral artery
• two terminals, dorsal artery and deep artery

Question 8

Course and branches of perineal A

Answer 8

1. enters Ischiorectal fossa by piercing, medial wall of pudendal canal.
2. It is then pierces perineal membrane to enter superficial perineal pouch
3. it divides into transverse perineal artery, which supplies the superficial and transverse perineal muscles And posterior scrotal artery 🚹/ labial artery 🚺, which supplies scrotum or labia majora

Question 9

course of artery of bulb

Answer 9

1. It arises in deep perineal pouch
2. it’s pierces perineal membrane
3. it enters bulb of penis and runs through corpus spongiosum on side of ureter 🚹 or supplies bulb of vestibule in female 🚺

Question 10

course of urethral A

Answer 10

1. Arises in deep perineal pouch
2. pierces perineal membrane
3. supplies urethra

Question 11

course of dorsal artery of penis or clitoris

Answer 11

pass on dorsal surface of penis or clitoris

Question 12

course of deep artery of penis or clitoris

Answer 12

enters corpus cavernosum

Question 13

Origin of pudendal nerve

Answer 13

One of two terminal branches of the sacral plexus (S2,3,4)

Question 14

Course of pudendal nerve

Answer 14

1. Leaves the pelvis through greater sciatic foreman
2. crosses sacrospinous ligament and enters through lesser sciatic foramen
3. it enters pudendal canal, accompanying internal pudendal vessels
4. In the pudendal canal, it gives inferior rectal nerve

Question 15

termination of Pudendal Nerve

Answer 15

It ends by dividing into two terminal branches:
* perineal nerve
* Dorsal nerve of penis/clitoris

Question 16

Innumerate branches of pudendal nerve

Answer 16

• Inferior rectal nerve
• perineal nerve
• dorsal nerve of penis/clitoris

Question 17

Branches of perineal nerve

Answer 17

2 terminal branches:
* posterior scrotal/labial branches
* muscular branches, supplying superficial and deep perineal muscles
