Skin Disease

The disease's name is dyshidrotic eczema. The cause of this pattern of eczema is not fully understood but in some cases there is a history of allergic contact dermatitis especially to nickel. Very often no specific allergen is found despite extensive patch testing. This form of eczema is aggravated by stress. Dyshidrotic eczema appears as intensely itchy blisters on the hands, fingers and soles of the feet. Hand eczema occurs most frequently in persons who frequently have their hands immersed in water, such as food preparers, nurses, or florists. The warm, moist conditions in shoes provide an ideal situation in which foot dermatitis may also flourish. These eruptions often become chronic and can be severe. Chronic hand-and-foot eczema is similar to other forms of dermatitis in appearance. It may have itchy, scaly patches of skin that flake constantly. Or your hands may become red, cracked and painful. In some cases, the rash worsens into weepy bumps. Clearing up your hand eczema depends largely on how you change your day-to-day habits. You need to keep your hand moisturized. Yet, in lotions there is more water there is in a lotion or other moisturizer, the more likely it is to worsen your hand eczema. So-called "cream" moisturizers contain more water than oil. When the water evaporates they have a net drying effect on the skin. (They are called cream moisturizers because they are white in color.) So the very best moisturizer for hand eczema is a greasy one. It has very few ingredients, holds the skin's natural moisture in and provides a protective barrier to keep irritants out. Another way to treat it is by avoid scented lotions & soaps. Always keep your hands dry but moisturized at the same time. There aren't any real treatments for it but i have this disease and i just but double antibiotic and some of my Triamcinolone acetonide for my regular ezema.

What is the significance of brain plasticity? How does the mapping of the brain explain various fetishes?

The significance of brain plasticity is  for the ability of the brain to reorganize neural pathways based on new experiences.It can change with new experiences and allows us to obtain more knowledge.
The way the brain is mapped out is why people have certian fetishes. The most common fetish is feet because it is right next to the genitalia area of the brain. The next two common fetishes are legs and trunk(abs) and i think those are actually more common than feet because feet are ugly to me! lol But the throat, teeth, tounge and mouth area are farthest from the genitalia area in the brain they are more of the rare fetishes.

Sense of taste

Taste not only is from your taste buds which are the bumps on you tounge but taste also comes from your nose. I never really noticed this until our jelly bean lab. Our throats also have taste recptors but the tounge has more. The nose just increases the taste of the food or drink or undesirable flavor with a scent of the item being tasted. That is why when you are sick you tend not to taste your food as well because you r nose is stuffed with boogers. For example when you are eating pizza i notice when i am sick i don;t taste the spices as much but when m nose is fine i taste almost every ingredient in the pizza. And this is all due to flavor being sensed by smell. On the tounge you have 4 most common taste which are salt, sweet, bitter and sour.

visual blog

Due to perception we are able to view things in different ways. We view objects by distinguishing a forground and a back ground. And Professor Edgar Rubin has this famous illuison of two faces in the black back ground and a vase in the white background. I have seen this picture numerous amount of time so I automatically see both the faces and the vase. BUt if i remember correctly when i had first seen this illusion i thought there were only a vase and i saw this picture on the back of the apple jacks cereal box. (: The other illuison on the web site was of the two tables. At first glance it looks like one is longer and narrow while the other one is shorter and widers. But when placed together they are exactly the same size.It was just the way they were set up that made them look differently.
The other picture of the two men one that is close up and the other one that is in a distance was really tricky for me! They look completely differentl but in reality they are the same size! The smiling ladies was scary when you flipped them over because when they were upside down it looks at first glance that both are smiling but really they have messed up on of the faces by lipping the smile and eyes which looks super scary too me...

Why is it important that the body have two control systems rather than one?

Why is it important that the body have two control systems rather than one?

The bodies two control systems are the endocrine and nervous system. The nervous system includes the brain, spinal cord, nerves, and nerve networks. These parts are all essential to life and communication throughout the body. The endocrine system uses glands in the body to secrete hormones, meaning it also helps with communication. The hormones can regulate metabolism, growth, blood pressure, and digestion. These two systems interact in various ways. The hypothalamus connects both of these systems. They are important because they deal with different parts of the body. However, they both send important information throughout the body. They keep humans living and healthy, by working together.
