1
Q

What does the vesico-ureteric mechanism?

A

Protects the nephrons from any damage secondary to retrograde transmission of back pressure or infection from the bladder

2
Q

What rate does the bladder fill at?

A

0.5-5mls/min

3
Q

What are the 2 components of the urinary tract?

A

Upper tract

  • Kidneys and ureters
  • A low pressure distensible conduit with intrinsic peristalsis

Lower tract

  • Bladder and urethra
  • A low pressure storage of urine
4
Q

A

Hypogastric nerve
Sympathetic
T10-S2

5
Q

What nerves are involved in the voiding of urine?

Pelvic nerve
Parasympathetic
S2-S4

6
Q

What nerves are involved in the voluntary control of the bladder?

A

Pudendal nerve
Somatic
S2-4

7
Q

What cortical activity is involved in the filling of the bladder?

A

Cortical activity activates a reciprocal guarding reflex by Rhabdosphincter contraction; increase sphincter contraction & resistance.
-Activates symptathetic pathway
-Reciprocal inhibition of the parasympathetic pathway
M
-Mediates contraction of bladder base and proximal urethra

8
Q

What occurs during bladder emptying?

A

Cortical influence from pontine micturition centre leads to activation of parasympathetic pathway and inhibition of the sympathetic pathway
