The iPhone 6s and 6s Plus are made from a 7000 Series aluminum alloy, which is stronger and more durable than the 6000 series used in the previous-generation iPhones. Apple's also updated the devices with stronger glass, made using a dual ion exchange process.
Two important sacral nerves to the functioning of the bladder and bowel are the pudendal nerve and the pelvic splanchnic nerve. Through a series of reflexes and signals the nerves and the bladder and bowel coordinate with the pelvic floor muscles and external urinary and anal sphincters.
Nerve messages go back and forth between the brain and the muscles that control bladder emptying. If these nerves are damaged by illness or injury, the muscles may not be able to tighten or relax at the right time. In people with neurogenic bladder, the nerves and muscles donât work together very well. As a result, the bladder may not fill or empty the right way. Bladder muscles may be overactive and squeeze more often than normal and before the bladder is full of urine. Sometimes the muscles are too loose and let urine leak before youâre ready to go to the bathroom (incontinence).
