Second trimester: Baby sucks, swallows, blinks and dreams

During the second trimester, your baby's brain is directing steady contractions of the diaphragm and chest muscles (think of them as practice breathing movements). Baby's first sucking and swallowing impulses kick in around 16 weeks. By 21 weeks, your baby's natural reflexes will allow him to swallow several ounces of amniotic fluid every day. And all of that swallowing means baby's tasting, too, another sense that's now in full gear.
At around 18 weeks of pregnancy, you'll feel baby's first kick (but don't worry if it takes a few weeks longer — that's common, especially among first-time moms). Around the same time, your baby's nerves become covered with myelin, a protective insulation that speeds messages between nerve cells (myelin continues to grow until your baby's first birthday). And at 24 weeks, another big reflex occurs: Blinking.
At the tail-end of trimester two, your little one's brainstem (controlling heart rate, breathing, blood pressure) is almost entirely mature, resting just above the spinal cord but below the cerebral cortex (the last area to mature). By now, the fetal nervous system is developed enough so your baby is startled by loud noises outside the womb — and may even turn his head toward the sound of your voice! Another exciting development: At 28 weeks, fetal brainwave activity features sleep cycles, including REM (the stage when dreaming occurs).

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 discussion related to each of the major

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 Zinc plays a role in many aspects of the bod
