Nerve supply of the bladder is explained in the figure below with differences between the autonomic and autonomous bladder.

---|---|
Damage above sacral plexus (Suprasacral) | Damage to sacral plexus |
UMN Type (Spastic) | LMN Type (Atonic) |
Reflex emptying of the bladder | Reflex activity lost |
Small capacity -> Hypertonic bladder empty suddenly | Overflow incontinence (No spinal reflex) |
Incomplete evacuation -> Residual urine (+) | High residual volume ( >200-300 cc ) |
