Pelvic Cavity

Question 1

Ureter vasculature

Answer 1

Inferior vesical & uterine vessels supply the
ureters in the pelvic region.

It also receives blood from renal, gonadal, common iliac, internal iliac, & superior vesical arteries.

Question 2

Ureter lymph drainage

Answer 2

Lymph drains into the lumbar, common iliac, external iliac & internal iliac lymph nodes.

Question 3

Ureter innervation

Answer 3

autonomic innervation is from the renal, aortic, superior/inferior hypogastric plexuses.

Question 4

Bladder vasculature

Answer 4

superior vesical (M/F), inferior vesical (M) & vaginal (F)

Question 5

Bladder lymph

Answer 5

Lymph drains to the external iliac (superior part) & internal iliac lymph nodes (inferior part) (M/F)

Question 6

Bladder innervation

Answer 6

Sympathetic – contracts internal urethral sphincter during ejaculation
• Hypogastric plexuses

Parasympathetic – motor to detrusor muscle and inhibitory to the internal sphincter of males
• Pelvic splanchnic
• Inferior hypogastric plexus Visceral sensory
• Inferior parts – follow parasympathetic fibers
• Superior parts – follow sympathetic fibers

Question 7

Female urethra vasculature

Answer 7

internal pudendal & vaginal arteries.

Question 8

Male urethra vasculature

Answer 8

prostatic branches of the inferior vesical & middle rectal (intramural part & prostatic); dorsal artery of the penis (intermediate & spongy)

Question 9

Female urethra lymph drainage

Answer 9

Lymph drains mainly to the sacral & internal iliac lymph nodes. A few vessels drain to the superficial/deep inguinal lymph nodes.

Question 10

Male urethra lymph drainage

Answer 10

Lymph drainage is to the internal iliac (intramural, some prostatic & intermediate parts), external iliac (some prostatic & proximal spongy part) & deep inguinal lymph nodes (distal spongy part).

Question 11

Female urethra innervation

Answer 11

Innervation: nerves arise from the vesical nerve plexus and the pudendal nerve. Visceral afferents from most of the urethra run in the pelvic splanchnic nerves, but the termination receives somatic afferents from the pudendal nerve.

Question 12

Male urethra innervation

Answer 12

autonomic nerves arise from the prostatic nerve plexus (prostate & intermediate parts) as well as the dorsal nerve of the penis (spongy part).

Question 13

ductus (vas) deferens vasculature

Answer 13

artery of the ductus (vas) deferens usually branches off the superior vesical artery but it may also come from the inferior vesical artery.

Question 14

ductus deferens lymph drainage

Answer 14

Lymph drainage is to the external iliac lymph nodes.

Question 15

Ductus deferens innervation

Answer 15

autonomic nerves composed mainly of sympathetic fibers derived from the larger pelvic plexus.

Question 16

Seminal vesicle vasculature and lymph drainage

Answer 16

inferior vesical & middle rectal arteries. Lymph drainage is to the external iliac (superior part) & internal iliac (inferior part) lymph nodes.

Question 17

Seminal vesicle innervation

Answer 17

from the prostate nerve plexus (autonomics).

Question 18

Ejaculatory duct vasculature and lymph

Answer 18

artery to the ductus (vas) deferens. Lymph drainage is to the external iliac lymph nodes.

Question 19

Prostate vasculaure

Answer 19

Prostate lymphprostatic arteries that originate mainly from the
inferior vesical but may also branch directly from the internal pudendal and middle rectal arteries. The prostatic venous plexus drains the deep dorsal vein of the penis.

Question 20

Prostate lymph

Answer 20

Lymph drainage is to the internal iliac mainly but also the sacral lymph nodes.
