Answer 1

1. General structure and function of the nervous system. The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
2. Benefit sleep provide to the nervous system and to the body in general. During sleep, your sympathetic nervous system – which controls your fight or flight response – gets a chance to relax. Studies have shown that when we're deprived of sleep, sympathetic nervous system activity increases, which is also mirrored by an increase in blood pressure.
3. How sleep disturbances effects to your physical, mental and emotional health. Lack of sleep is linked to a number of unfavorable health consequences including heart disease, type 2 diabetes, and depression. Some psychiatric conditions can cause sleep problems, and sleep disturbances can also exacerbate the symptoms of many mental conditions including depression, anxiety, and bipolar disorder.
