- Puboprostatic
5
Q
Micturition
A
- Sphincter muscles relax and detrusor muscles contract
- Parasympathetic= pelvic splanchnic nerves from S2-s4 stimulates detrusor and inhibits sphincters
- Sympathetic= L1-L2 from hypogastric plexus, stimulates sphincters to contract
- Somatic= S2-S4 control of external sphincter
6
Q
Internal sphincter
A
- Smooth muscle
- Involuntary control
