First trimester: Baby starts moving

A mere 16 days after conception, your fetus's neural plate forms (think of it as the foundation of your baby's brain and spinal cord). It grows longer and folds onto itself, until that fold morphs into a groove, and that groove turns into a tube — the neural tube.
Once the neural tube closes, at around week 6 or week 7 of pregnancy, it curves and bulges into three sections, commonly known as the forebrain, midbrain and hind brain. Just to the rear of the hindbrain sits the part that will soon turn into your baby's spinal cord. Soon, these areas bubble into those five different regions of the brain that we're most familiar with: the cerebrum, cerebellum, brain stem, pituitary gland and the hypothalamus. Of course, all of these fetal brain areas need more time to be fully up and running!
At the same time, special neural cells form and move throughout the embryo to form the very beginnings of nerves. Your baby's nervous system is made up of millions upon millions of neurons; each of these microscopic cells have itty-bitty branches coming off of them so that they can connect and communicate with each other. With this comes baby's first synapses, which essentially means baby's neurons can communicate and create early fetal movements...like curling into the fetal position.
Other movements follow quickly, with your fetus wiggling his developing limbs at around 8 weeks. By the end of the first trimester, your baby-to-be has garnered quite a repertoire of motion, though you won't be able to feel it quite yet. And at about the same time as baby first wiggles his limbs, he begins to develop the sense of touch.

Benefits of Minerals ..2

Benefits of Minerals ..1 Brought to U.... http://successgain.us       and      http://successgain.info 2.... Major vs. Trace Minerals Minerals that are considered vital to good health, fitness, and mental well-being are divided into two primary groups: major minerals and trace minerals. Major minerals are considered minerals that the body requires in relatively large amounts and include calcium, chloride, magnesium, phosphorus, potassium, and sodium, and sulfur. The human body requires major minerals in larger quantities and are considered macro-minerals. On the other hand, trace minerals are required by the human body in much lower quantities and are considered micro-minerals. Trace minerals include chromium, copper, iodine, fluorine, iron, manganese, molybdenum, selenium, and zinc. In both cases, consuming an adequate level of both the major and trace minerals is required for good health and wellness. For a more detailed discus...

Mineral Deficiency ...4

Mineral Deficiency ...4 Brought to U.... http://successgain.us       and      http://successgain.info 6...  Potassium deficiency Potassium is a mineral that functions as an electrolyte. It’s required for muscle contraction, proper heart function, and the transmission of nerve signals. It’s also needed by a few enzymes, including one that helps your body turn carbohydrates into energy. The best sources of potassium are fruits and vegetables. The most common cause of potassium deficiency is excessive fluid loss. Examples can include extended vomiting, kidney disease, or the use of certain medications such as diuretics. Symptoms of potassium deficiency include muscle cramping and weakness. Other symptoms show up as constipation, bloating, or abdominal pain caused by paralysis of the intestines. Severe potassium deficiency can cause paralysis of the muscles or irregular heart rhythms that may lead to death. 7... Zinc deficiency ...
