Flashcards in Anatomy: Nerves Deck (37):
1

Where do sympathetic nerve fibres leave the spinal cord to innervate the urinary tract

T10 -L2

2

How do sympathetic nerves that innervate the kindey actually reach it

Within abdominopelvic splanchnic nerves

3

Where do the sympathetic nerves synapse

at the abdominal sympathetic ganglia

4

Which cranial nerves are parasympathetic

III, VII, IX, X

5

How do parasympathetic nerves that innervate the kidney and ureter reach them

within the vagus nerve

6

How do parasympatheitc nerve fibre which innervate the bladder reach the bladder

within pelvic splanchnic nerves

7

Where do pelvic splanchnic nerves leave the spinal nerves

S2, S3, S4

8

Which part of the renal system have somatic fibres going to them

those in the perineum (the urethra) ONLY

9

What stimulates contraction of the detrusor muscle

parasympathetic fibres from S2, 3 and 4 pelvic splanchnic nerves

10

What stimulates the interanl urethral sphincter to contract

sympathetic fibres

11

what stimulate the internal urethral spnincter to relax (in males)

parasympathetic fibres

12

What stimulates external urethral sphincter to contract

pudendal nerve (somatic motor) S2, 3, 4

13

What stimulaters the levator ani to contract

the nerve to the levator ani (S3, S4)

14

Where do visceral afferents from the kidneys enter the spinal cord

T11 to L1

15

Where do visceral afferent from the ureters enter the spinal cord

T11 to L2

16

Where do visceral afferent from the part of the bladder touching the peritoneum enter the spinal cord

enter at T11-L2
travel alongside sympathetic fibres

17

Where is pain from the superior surface of the bladder felt

suprapubic

18

Where does the visceral affertents drom the rest of the bladder enters the spinal cord

alongside parasympathetics on the S2, 3, 4

19

where are visceral afferents from the proximal urethra entering the spinal cord

alongside the parasympathetics at S2, 3, 4

20

Where do somatic sensory from the distal urethra entering the spinal cord

pudendal nerve at levels S2, 3, 4

21

Where do visceral afferents from the testes enter the spinal cord

T10-T11
