A graphic representation of the interface between skin epithelium and the underlying connective tissue the reticular dermis. The dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain.part from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins.

Most of us think of sleep walking or sleep eating as strange, but separate and distinct from obstructive sleep apnea, but a recent study showed that in a group of people with obstructive sleep apnea, almost 10% had one or more of the parasomnias (sleep walking, sleep eating, sleep hallucinations and paralysis, etc.).
Some common sleep disorders include sleep apnea (stops in breathing during sleep), narcolepsy and hypersomnia (excessive sleepiness at inappropriate times), cataplexy (sudden and transient loss of muscle tone while awake), and sleeping sickness (disruption of sleep cycle due to infection). Sleep apnea, obstructive sleep apnea, obstruction of the airway during sleep, causing lack of sufficient deep sleep, often accompanied by snoring. 2  Other forms of sleep apnea are less common. 3  When air is blocked from entering into the lungs, the individual unconsciously gasps for air and sleep is disturbed.
