===Central Intregration===
===Central Intregration===
The co-ordination of the urethralis and detrusor muscles from information recieved from the stretch receptors occurs in the '''pons'''. This micturition centre also branches to the thalamus, cerebellum and cerebral cortex. It is the cerebral cortex that is responsible for voluntary control of micturition.

===The Muscles===
The motor components of the reflex are the [[Bladder - Anatomy & Physiology #Detrusor Muscle| Detrusor Muscle]], [[Bladder - Anatomy & Physiology #Internal Urethral Sphincter| Internal Urethral Sphincter]] and the [[Bladder - Anatomy & Physiology #External Urethral Sphincter| External Urethral Sphincter]]. They former two are supplied by the autonomic nervous system with the latter being of somatic innervation.
