sphincter muscles surrounding the urethra. These muscles can be consciously contracted to prevent the flow of urine until the person decides to release it.
Urination is both a voluntary and involuntary process. The act of releasing urine is primarily under voluntary control, allowing us to choose when and where to empty our bladder. However, the reflex to empty the bladder when it becomes full is an involuntary process controlled by the nervous system.
Voluntary muscles are under conscious control and are responsible for movement in the body. They allow us to perform activities such as walking, running, and picking up objects. These muscles can be activated and controlled at will.
Neural control of urination involves the coordination of the bladder muscles and sphincters by the nervous system to regulate the storage and release of urine. The process involves complex interactions between the brain, spinal cord, and peripheral nerves to initiate and control the urination reflex. Disruption in this neural control can lead to urinary incontinence or retention issues.
The brainstem controls the involuntary muscles and the cerebellum controls the voluntary muscles.
