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.
Sacral Nerves. The brain tells the bladder and bowel what to do by sending electrical signals to the muscles in the pelvic floor, the sphincters, the urethra as well as the bladder and rectal area. The messages or impulses sent by the brain to the pelvic area are carried by a system of special fibres called nerves.
Mechanism of Action. GnRH, secreted in pulses from the hypothalamus, stimulates pituitary release of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH subsequently stimulates testosterone secretion, predominantly by the testes (Figure 1).(Enlarge Image). Figure 1. Figure 1. Endocrine control of the prostate gland.echanism of Action.
