Breonna Mosely 7/17/2014 Dr. Ganser Endocrine system effects on Sleep Deprivation Deprived sleep is a universal widespread problem observed in both children and adults. Sleep is a vital process that helps in the functioning of learning‚ memory processing‚ cellular repair‚ and brain development. Statistics show that the average total hours of sleep have decreased per person to less than 7 hours per night over the past 3 to 4 decades. Many people experience sleep loss due pressures at work

infrequently for several years. In this particular disease‚ when one thing goes wrong in your immune system‚ that is the part of the body which fights off viruses‚ bacteria‚ and germs‚ our immune system is not able to function properly. Commonly our system produces proteins referred to as antibodies that defend the body from these invaders. Lupus is an autoimmune disease‚ which suggests that your system cannot tell the distinction between these foreign invaders and your body’s healthy tissues and creates

8th period Epinephrine (Adrenaline) (C9H13NO3) Adrenaline is a hormone that is produced in the adrenal medulla‚ which is in the inner adrenal gland. This gland sits atop the kidney. When put under stress this gland is stimulated by the nervous system and releases adrenaline into the blood stream. The release of adrenaline is a three step process. First‚ the hypothalamus produces hormones that stimulate the pituitary gland. Next‚ the pituitary gland then produces corticotropin hormones which are

Background Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells‚ smooth muscle cells are not striated‚ and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system‚ and do not contract voluntarily. Smooth muscle contracts slowly‚ and does not exhibit the characteristic “twitch” seen in skeletal muscle. In addition‚ smooth muscle is not prone to muscle fatigue‚ making it an ideal component of sphincter muscles
