Where is the pontine micturition center?

medial dorsal pons
The Pontine micturition center(PMC) is located in the medial dorsal pons, close to, or includes the lateral dorsal tegmental nucleus and locus coeruleus. [4] Upon stimulation, PMC exerts dual effects of producing detrusor muscle contraction and urethral sphincter relaxation with consequent micturition.

What does the pontine storage center do?

The Pontine micturition center (PMC, also known as Barrington’s nucleus) is a collection of neuronal cell bodies located in the rostral pons in the brainstem involved in the supraspinal regulation of micturition. When activated, the PMC relaxes the urethral sphincter allowing for micturition to occur.

Where is the control center for micturition?

brain stem
The pontine micturition control centre is in the brain stem. It is responsible for the co-ordination of the sphincter relaxation and the detrusor contraction. It works like a ‘switch’ controlling storage and voiding.

What part of the brain controls micturition?

The pons is responsible for coordinating the activities of the urinary sphincters and the bladder. The mechanical process of urination is coordinated in an area of the pons known as the pontine micturition center (PMC).

Where is the pontine micturition center located in the brain?

Anatomical terms of neuroanatomy. [edit on Wikidata] The Pontine micturition center (PMC, also known as Barrington’s nucleus) is a collection of neuronal cell bodies located in the rostral pons in the brainstem involved in the supraspinal regulation of micturition.

Is the pontine micturition center essential for bladder dysfunction?

Brainstem Lesions Although the pontine micturition centeris essential for micturition, the rarity of brainstem lesions in clinical practice makes it less common to encounter bladder dysfunction secondary to brainstem lesions.

Where is the micturition center located in the body?

The pontine micturition center coordinates the activity of motor neurons of the urinary bladder and the urethral sphincter (the nuclei of both are located in the sacral spinal cord), receiving afferent input via the periaqueductal gray.

Where is the PMC located in the pontine tegmentum?

The PMC in the pontine tegmentum is the site of the coordination of the spino-bulbo-spinal micturition reflex (Barrington, 1921; Fowler et al., 2008; see Chapter 7). The PMC is located in or adjacent to the locus coeruleus, and the projecting fibers from the PMC to the sacral preganglionic cells are thought to be glutamatergic.
