Which myotome pattern includes bladder function?

The myotome pattern that includes bladder function is associated with the S4 segment of the spinal cord. This area is part of the sacral region and plays a critical role in innervating structures related to pelvic function, including the bladder. The S4 nerve roots specifically contribute to the autonomic and somatic control of bladder sphincters, thus influencing urinary retention and the ability to void.

Understanding the function of myotomes is important in assessing spinal cord injuries or neurological conditions that may affect bladder control. Knowledge of which spinal segments control specific functions helps in guiding rehabilitation and treatment strategies for patients with dysfunctions in this area.
