BIO 160: Chapter 6: The integumentary system Flashcards Preview

The skin receives the most physical damage from the body, but it is more resistant than other organs and recovers from trauma. Epidermal cells are filled with rigid protein keratin and are bound by strong desmosomes to make this epithelial cell durable. There are few infectious organisms penetrating intact skin. Bacteria and fungi colonize the surface, but their amount is controlled by their relatively dry, slightly acidic (pH 4 to 6) and certain protective antimicrobial peptides (called Dermsidine and Defensin) .

The spiky layer consists of several layers of keratinocytes. For most skin this is the thickest layer, but for thick skin usually the stratum corneum is beyond that. The deepest cells of the spinous layer are still mitotic, but as they are pushed further they stop dividing. Instead, they produce more and more keratin filaments which cause the cells to flatten. Dendritic cells are also found throughout the spinous layer. Epidermal keratinocytes also bind together via tight junctions, which plays an important role in skin moisture retention.

The skin system includes skin, nails and toenails and other structures including glands. Unlike other body systems throughout the body system, the integument system is not limited to one area or area of ​​the body, instead the cover system covers the entire body. The dermis, the middle layer of the skin, includes blood vessels with two sublayers, reticular and papillary sublayers, both of which are elastic to the skin as during skin swelling under the skin during pregnancy Gives sex and elasticity. Skin stretch

The state of the skin is any condition that affects the skin system including the entire body surface of the organ system, such as skin, hair, nails, related muscles and glands. The state of the human integument system constitutes a wide range of diseases also known as skin diseases. Very few skin diseases account for most of the doctor's examination, but thousands of skin diseases are listed. Three common skin diseases caused by viral infections are herpes simplex, herpes zoster and tick.

The objective was to compare the ectoderm and digestive system of rats with the system of sugarcane toads. Introduction of the underlying system by Adam.com, Inc. It is defined as a wide system that hurts skin, hair, nails, sweat glands and sebaceous glands. It also includes special neuroreceptors that remind us of changes around us, such as touch, cold, fever, pain, and stress. - Introduction Aroma and aroma are said to be "derived from chemical stimulation, sense of taste and smell" (Rawson, 2003). In summary, despite the fact that these sensory systems are thought to be very different in physiology and anatomy, these sensations constitute a so-called chemical sensation. However, they have "regenerative ability and their susceptibility to aging and age related diseases" (Rawson, 2003).
