The hypothalamus controls body temperature, thirst, appetite, sleep patterns, and other processes in our bodies that happen automatically. So drink up folks and enjoy the rest of your life. Vitamin D is often called the sunshine vitamin because we produce it when exposed to sunlight. It was done in 20min, I could have fallen asleep but I chose to watch the monitor. I'm an athlete, my girlfriend is a dancer, how will this benefit us? Share Reply to Monique Robillard.
Focusing on Function
In children, low levels of exposure have been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells.
It is important to recognize all the ways a child can be exposed to lead. Children are exposed to lead in paint, dust, soil, air, and food, as well as drinking water. If the level of lead in a child's blood is at or above the CDC action level of 5 micrograms per deciliter, it may be due to lead exposures from a combination of sources.
Infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water. Lead can accumulate in our bodies over time, where it is stored in bones along with calcium. During pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough dietary calcium. Lead can also cross the placental barrier exposing the fetus to lead.
This can result in serious effects to the mother and her developing fetus, including:. Lead can also be transmitted through breast milk.

This information applies to most situations and to a large majority of the population, but individual circumstances may vary.
Some situations, such as cases involving highly corrosive water, may require additional recommendations or more stringent actions. Your local water authority is always your first source for testing and identifying lead contamination in your tap water. Many public water authorities have websites that include data on drinking water quality, including results of lead testing.
EPA requires all community water systems to prepare and deliver an annual water quality report called a Consumer Confidence Report CCR for their customers by July 1 of each year. Contact your water utility if you'd like to receive a copy of their latest report. If your water comes from a household well or other private water supply, check with your health department, or with any nearby water utilities that use ground water, for information on contaminants of concern in your area.
EPA's Public Notification Rule requires public water systems to alert you if there is a problem with your drinking water. Homes may have internal plumbing materials containing lead. Since you cannot see, taste, or smell lead dissolved in water, testing is the only sure way of telling whether there are harmful quantities of lead in your drinking water. In infants, signs of a vitamin B12 deficiency include failure to thrive , problems with movement, delays in reaching the typical developmental milestones, and megaloblastic anemia.
Large amounts of folic acid can hide a vitamin B12 deficiency by correcting megaloblastic anemia, a hallmark of vitamin B12 deficiency. But folic acid does not correct the progressive damage to the nervous system that vitamin B12 deficiency also causes.
For this reason, healthy adults should not get more than 1, mcg of folic acid a day. Scientists are studying vitamin B12 to understand how it affects health. Here are several examples of what this research has shown:. Vitamin B12 supplements along with folic acid and vitamin B6 do not reduce the risk of getting heart disease. Scientists had thought that these vitamins might be helpful because they reduce blood levels of homocysteine , a compound linked to an increased risk of having a heart attack or stroke.
As they get older, some people develop dementia. These people often have high levels of homocysteine in the blood. Vitamin B12 with folic acid and vitamin B6 can lower homocysteine levels, but scientists don't know yet whether these vitamins actually help prevent or treat dementia. Advertisements often promote vitamin B12 supplements as a way to increase energy or endurance.
Except in people with a vitamin B12 deficiency, no evidence shows that vitamin B12 supplements increase energy or improve athletic performance. Vitamin B12 can interact or interfere with medicines that you take, and in some cases, medicines can lower vitamin B12 levels in the body. Here are several examples of medicines that can interfere with the body's absorption or use of vitamin B Tell your doctor, pharmacist , and other healthcare providers about any dietary supplements and medicines you take.
They can tell you if those dietary supplements might interact or interfere with your prescription or over-the-counter medicines or if the medicines might interfere with how your body absorbs, uses, or breaks down nutrients. People should get most of their nutrients from food, advises the federal government's Dietary Guidelines for Americans.
Foods contain vitamins, minerals , dietary fiber and other substances that benefit health. In some cases, fortified foods and dietary supplements may provide nutrients that otherwise may be consumed in less-than-recommended amounts. For more information about building a healthy diet, refer to the Dietary Guidelines for Americans and the U. Department of Agriculture's MyPlate. All neurons relay information to each other through a complex electrochemical process, making connections that affect the way we think, learn, move, and behave.
When you learn things, messages travel from one neuron to another, over and over. Then the brain creates connections or pathways between the neurons, so things become easier and you can do them better and better.
In young children, the brain is highly adaptable. In fact, when one part of a young child's brain is injured, another part may learn to take over some of the lost function. But as we age, the brain has to work harder to make new neural pathways, making it more difficult to master new tasks or change established behavior patterns. That's why many scientists believe it's important to keep challenging your brain to learn new things and make new connections — it helps keep the brain active over the course of a lifetime.
Memory is another complex function of the brain. The things we've done, learned, and seen are first processed in the cortex, and then, if we sense that this information is important enough to remember permanently, it's passed inward to other regions of the brain such as the hippocampus and amygdala for long-term storage and retrieval.
As these messages travel through the brain, they create pathways that serve as the basis of our memory. Different parts of the cerebrum are responsible for moving different body parts. The left side of the brain controls the movements of the right side of the body, and the right side of the brain controls the movements of the left side of the body.
When you kick a soccer ball with your right foot, for example, it's the left side of your brain that sends the message allowing you to do it. A part of the peripheral nervous system called the autonomic nervous system is responsible for controlling many of the body processes we almost never need to think about, like breathing, digestion, sweating, and shivering.
The autonomic nervous system has two parts: The sympathetic nervous system prepares the body for sudden stress, like if you see a robbery taking place. When something frightening happens, the sympathetic nervous system makes the heart beat faster so that it sends blood more quickly to the different body parts that might need it.
It also causes the adrenal glands at the top of the kidneys to release adrenaline, a hormone that helps give extra power to the muscles for a quick getaway.
This process is known as the body's "fight or flight" response. The parasympathetic nervous system does the exact opposite: It prepares the body for rest.
It also helps the digestive tract move along so our bodies can efficiently take in nutrients from the food we eat. Your eyes may watch as your best friend walks toward you — but without the brain, you wouldn't even recognize her.
Pepperoni pizza sure is delicious — but without the brain, your taste buds wouldn't be able to tell if you were eating pizza or the box it came in. None of your senses would be useful without the processing that occurs in the brain. Because the brain controls just about everything, when something goes wrong, it's often serious and can affect many different parts of the body.
Inherited diseases, brain disorders associated with mental illness, and head injuries can all affect the way the brain works and upset the daily activities of the rest of the body. A tumor is an abnormal tissue growth in the brain.
A tumor in the brain may grow slowly and produce few symptoms until it becomes large. Or a tumor can grow and spread rapidly, causing severe and quickly worsening symptoms. Brain tumors can be benign or malignant. They usually grow in one place and may be curable through surgery if they're located in a place where they can be removed without damaging the normal tissue near the tumor. A malignant tumor is cancerous and more likely to grow rapidly and spread.
CP affects the motor areas of the brain. A person with cerebral palsy may have average intelligence or can have severe developmental delays or mental retardation. Cerebral palsy can affect body movement in many different ways. In mild cases, a person may have minor muscle weakness in the arms and legs.
In other cases, there may be more severe motor impairment — a person may have trouble talking and performing basic movements like walking. Epilepsy is a condition of the nervous system that can lead people to have seizures.
