Tough and resilient, protection is its number one job. Think of a parka you may wear in the winter. The inside is lined with soft fleece, providing a layer of warmth. But the outside is made of a strong waterproof material that lets nothing through. ]]> 2019-02-26 17:59:04 UTC https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335525769 dermis sluc0240 https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335529460 The dermis is the second and thickest layer of the three major layers of layers of skin, located between the epidermis and subcutaneous tissues, also known as the subcutis and the hypodermis. The dermis contains blood vessels, lymph vessels, hair follicles, and glands that produce sweat, which helps regulate body temperature, and sebum, an oily substance that helps keep the skin from drying out. Sweat and sebum reach the skin's surface through tiny openings in the skin that act as pores.]]> 2019-02-26 18:00:37 UTC https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335529460 hypodermis sluc0240 https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335534151 The hypodermis (subcutaneous layer, or superficial fascia) lies between the dermis and underlying tissues and organs. It consists of mostly adipose tissue and is the storage site of most body fat. It serves to fasten the skin to the underlying surface, provides thermal insulation, and absorbs shocks from impacts to the skin.]]> 2019-02-26 18:05:35 UTC https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335534151 collagen and the skin sluc0240 https://padlet.com/sluc0240/5dw1vhpyttu4/wish/335534209
  • Collagen is the most abundant protein in the body, and gives structure to your skin, bones, muscles, and all other connective tissue.As the most abundant protein in the body, collagen is available in your muscles, skin, blood, bones, cartilage, and ligaments.Other lifestyle habits that can bring collagen production to a screeching halt include smoking, sun exposure, and an unhealthy diet. Some health conditions may also deplete your collagen storage.

    A papule is an area of abnormal skin tissue that is less than 1 centimeter around. A papule has distinct borders, and it can appear in a variety of shapes. Papules are often called skin lesions, which are essentially changes in the color or texture of your skin. Sometimes, papules cluster together to form a rash.In most cases, papules are not serious and can be relieved with home treatments. However, if the papules appear soon after you start a new medication, consult your doctor immediately.
