The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear hairless. There are two general types of skin, hairy and glabrous skin (hairless). The adjective cutaneous literally means "of the skin" (from Latin cutis, skin). Because it interfaces with the environment, skin plays an important immunity role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discoloured and depigmented. In humans, skin pigmentation (affected by melanin) varies among populations, and skin type can range from dry to non-dry and from oily to non-oily. Such skin variety provides a rich and diverse habitat for bacteria that number roughly 1000 species from 19 phyla, present on the human skin. Structure
Human skin shares anatomical, physiological, biochemical and immunological properties with other mammalian lines, especially pig skin.
Premature infants who have been given large amounts of benzyl alcohol (99–405 mg/kg/day) have experienced "gasping syndrome". Although enoxaparin is used to prevent blood clots, pregnancy alone can raise a womans risk of clotting. Side effects

Boxed warning
The FDA issued a revision to the boxed warning for enoxaparin in October 2013. The revision recommends exercising caution regarding when spinal catheters are placed and removed in persons taking enoxaparin for spinal puncture or neuroaxial anesthesia. It may be necessary to delay anticoagulant dosing in these persons in order to decrease the risk for spinal or epidural hematomas, which can manifest as permanent or long-term paralysis. Persons at risk for hematomas may present with indwelling epidural catheters, concurrent use of medications that worsen bleeding states such as non-steroidal anti-inflammatory drugs (NSAIDs), or a past medical history of epidural or spinal punctures, spinal injury, or spinal deformations. The FDA recommends that at-risk persons be monitored for bleeding and neurological changes.
