Human skin

The human body has many amazing qualities and so many of them are made up of small proteins. Keratin is the main component of your hair, skin, and nails. Integrin acts a sort of messenger. Cadherin acts a binder, creating the structure of cells. So many different proteins help make the world turn waiting the human body, but they do different things. These are three important proteins. Keratin to is very important to the human body. Keratin is a big factor in making up your…

Acne is a treatable skin condition, which affects individuals of all ages. It occurs when hair follicles become clogged with oil and dead skin cells. Each pore on the skin is an opening to a follicle and attached to the follicle is a strand of hair and a sebaceous gland that produces and secretes sebum. The sebum is responsible for lubricating and softening the skin. Excess sebum production, accumulation of dead skin cells, and the increase of bacteria in the pores can contribute to the…

The human body is exceptionally durable relative to its size, especially against the inevitable. Aging occurs in everything- people, animals- even bacteria. While not everything ages the same, every living thing undergoes changes as they get older. These changes can affect the brain, organs, and skin. The real question is: how does aging affect the human body? The study of aging and how it affects the human body and humans in general is called Gerontology (Gerontology 1). Gerontology started…

spots on the skin were caused by a worm, which is why they named it Ringworm. Later on they realized that it was not caused by a worm and was actually a fungus. Symptoms Ringworm causes a crusted and scaly rash that may appear as round red patches on the skin. It also causes patches of hair loss or scaling on the scalp, itching, and blister-like lesions. Diagnosis Ringworm is usually obvious due to the location and appearance. If it isn’t obvious or wants to be confirmed then skin…

The skin is organized in two parts: the epidermis and the dermis. The epidermis is the thin outer covering of the skin. It serves as a permanent protective barrier that helps to keep out everything from water to microorganisms. Additionally, it has the task to renew itself if cut or damaged in anyway. Furthermore, the epidermis also help to produce a water resistant protein called keratin, which helps the growth of hair and fingernails. The dermis is the inner layer of the skin that is mostly…

Animals are not toys that humans can just play with. Testing on animals is not okay, animals have feelings and families too. If we test on animals, they soon could go extinct and it could have a harmful impact on humans as well. If animals are tested on because there are new alternatives. Animal testing also isn’t always accurate. Testing on animals is savage and fiendish. Animal testing has been going on for years; since 384 BC. Animal testing was invented to see if specific chemicals and some…

occur in mouse and rabbits (Ito et al., 2007). The way the skin responds to a wound differs between mammals. Humans for example respond to deep skin wound by blocking the hair formation and instead it forms a scar (Reynolds et al., 1999). On the other hand, rodents regenerate their hair after a wound (Ito et al., 2007). These differences between mammals are due to different concentration of some growth factors that are found in the skin (Gay et al., 2013). Gay and his colleagues showed that…

animal, does not guarantee it will work the same on a human. In fact, “The FDA (Food and Drug Administration) reports that 92 percent of drugs approved for testing in humans fail to receive approval for human use”. Many drugs pass animal testing but then prove to be dangerous for humans. For example, Vioxx, an arthritis drug, was sold in the United States because it passed animal testing, but then ended up causing over 60,000 deaths in humans (Limitations and Dangers). On the other hand,…

Shampoo is a vastly known consumer product that we all benefit from. When our skin produces sebum (a greasy substance) it primarily protects our hair and hair follicles, but can also make our hair look unclean. Sebum is hydrophobic, which fundamentally means it can’t be washed away with water. This is where the widespread consumer product shampoo comes into the picture. Much like you would find in dishwashing or laundry products, you can find detergent in shampoo. “Detergents lower the surface…
