Q

What parts of the renal system are supplied by somatic motor nerves?

A

Distal urethra and its external sphincter

18
Q

Where is pain from the kidney itself commonly felt?

A

“Loin” - posterior aspect of flank

19
Q

Where is pain from a calculus in the ureter felt?

A

From loin to groin

20
Q

Where is pain from the bladder felt?

A

Suprapubic region

21
Q

Where is pain from the urethra felt?

A

Perineum

22
Q

Visceral afferents from the kidney, ureters and part of the bladder run alongside what back to the spinal cord?

A

Sympathetic fibres

23
Q

Where do visceral afferents from the kidney enter the spinal cord?

A

T11-L1

24
Q

Where do visceral afferents from the ureters enter the spinal cord?

A

T11-L2

25
Q

Why do visceral afferents from the bladder travel back to the spinal cord in two different ways?

A

As it is partly in contact with peritoneum

26
Q

Visceral afferents from the bladder in contact with the peritoneum run alongside sympathetics/parasympathetics and enter at T11-L2

A

Sypathetics

27
Q

Visceral afferents from the bladder not in contact with the peritoneum run alongside parasympathetics back to which level?

A

S2-4

28
Q

Visceral afferents from the proximal urethra run alongside sympathetics/parasympathetics to S2-4?

A

Parasympathetics

29
Q

Somatic sensory fibres from the distal urethra are carried back to S2-4 within what nerve?

A

Pudendal nerve

30
Q

Visceral afferents from the testis run back to which levels of the spinal cord?

A

T10-11

31
Q

What type of nerve sense the stretch caused by bladder filling?

A

Visceral afferents

32
Q

The detrusor muscle contracting and internal urethral sphincter relaxing is under control of what nerve type?

A

Parasympathetics

33
Q

Relaxation of external urethral sphincter and levator ani muscles is carried out by what nerve type?

A

Somatic motor

34
Q

What are the nerve roots of the sciatic nerve?

A

L4-S3

35
Q

The femoral nerve is medial/lateral to the psoas major?

A

Lateral

40
Q

What nerve sits medial to the psoas major?

A
