The integument is the largest organ in the human body. It consists of the skin (epidermis and dermis) and associated appendages (hairs, nails, sweat and sebaceous glands) (Venus et al. 2011).
The epidermis is the outer layer of the skin. It is stratified squamous epithelial layer of ectoderm origin and it is devoid of blood vessels and consists of four layers: stratum corneum, stratum granulosum, stratum spinosum, and stratum basale. Keratinocytes are the major cells in the epidermis, but other cells are also present such as melanocytes, langerhans, and merkel cells. The dermis is a connective tissue layer of mesodermal origin below the epidermis and contains blood vessels, sensory structures, collagen, fibroblasts, and elastic fibers. Its
The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for
The outer germ layer is the ectoderm that forms the outer part of the body (the skin) and the nervous system. The endoderm, the inner germ layer, forms many inner structures, including the digestive tract and many glands associated with it. Lastly, the mesoderm is the middle layer which forms much of the skeleton and muscles.
There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat
The layers of the epidermis from deep to most superficial are the stratum basale, stratum spinosum, stratum grandulosum, stratum lacidum, and the stratum corneum. Each of these layers are unique due to the type of cells located in them which they are named after. They all together make up the epidermis, an avascular, superficial, and made up of epithelial cells.
Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.
Jacob Portman, a 16 year old boy, was very close to his grandfather as a child. His grandfather would show him pictures of strange people and places, and would tell Jacob fascinating stories about them. One particular story was about an old orphanage full of "peculiar" children, who all had something special, or peculiar, about them. He believed these stories as a child, but his father convinced him they were all just part of his grandfather's imagination. One day at work, however, Jacob received a distress call from his grandfather saying that "they" were here. Jacob rushes to his grandfathers house with the hopes of calming him down, and sees that the house was trashed. He eventually found his grandfather in the woods. He was near dead and
Dermis: one of the two layers of cells that form the skin. Specifically, it is the innermost layer.
The epidermis is the first layer of your skin and the only layer you actually see when you're walking down the street. If you're a surgeon, you probably see the dermis and subcutaneous fat as well, but for now, we are just covering the epidermis.
The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The vertebrate integumentary system is responsible for protection and thermoregulation. The skin covers the human body and also has appendages like hair and nails that all serve to protect the body from damage. The outer layer of the skin, the epidermis serves as a water resistant barrier protecting the body from absorption and leaking while we are swimming or when it is raining. This maintains homeostasis. This means that when we submerge ourselves in water we do not fill up with water and we also do not leak water. The skin serves to protect the body against pathogens and even damaging UV radiation too. The blood vessel and nerves in the dermis serve to warn us when we are in danger by signaling pain when the sun beats too much on a body
Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.
The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum
The dermis is the inner layer of the skin, and includes: hair follicles, nerves, sweat glands, small
Climate change is now a widely-accepted fact. We know that the earth is changing, and not necessarily for the better. Air quality is worsening, temperatures are increasing and fluctuating, greenhouse gases are rampant, and plants are changing their behavior. All of these add up to increased and worsening cases of asthma in children. Children are already more prone to sickness and disease, and climate change is only making it worse. According to the World Health Organization, 80% of the climate change health burden falls on children less than 5 years old. How tough is climate change for kids with asthma? There are several issues that climate change creates for young asthmatics.
Many of the companies face hardship when it comes to the careful selection of a network design. However, the company must select an efficient kind of network type. The design must conform to the merchandize involved in the transaction even if they are produced by the different companies. It is because, merchandises that happen to be in the same level, will be regulated and controlled similarly. Smaller businesses does not necessarily need to get assistance from a much bigger IT department. For such like an organization, a perfect network design is required to be up front all
