The cell cycle is a cycle rather than a linear process because the two daughter cells produced repeat the cycle. This process contains two main phases, interphase , in which the cell grows and synthesizes a copy of its DNA, and the mitotic M phase, during which the cell separates its DNA and divides into two new daughter cells. Following cytokinesis, during G1 phase the cells monitor environment for the potential growth factors, grow larger and once achieve the threshold size rRNA and overall protein content characteristic for a given cell type they start progression through S phase. After complete synthesis of its DNA, the cell enters the G2 phase where it continues to grow in preparation for mitosis. Following interphase, the cell transitions into mitosis, containing four sub stages:

Treatment[ edit ] There is no known cure for nerve damage caused by spina bifida. Standard treatment is surgery after delivery. This surgery aims to prevent further damage of the nervous tissue and to prevent infection; pediatric neurosurgeons operate to close the opening on the back. The spinal cord and its nerve roots are put back inside the spine and covered with meninges. In addition, a shunt may be surgically installed to provide a continuous drain for the excess cerebrospinal fluid produced in the brain, as happens with hydrocephalus. Shunts most commonly drain into the abdomen or chest wall. Pregnancy[ edit ] Standard treatment is after delivery.
Healthy Diet During Pregnancy
The recommended dietary allowance RDA for pregnant women is 1. A prenatal vitamin may be your best consistent source, but B-2 can be found in milk and dairy products, with smaller amounts present in soybeans, grains, and pork. Thiamine B-1 Thiamine is important for metabolism and development of the brain, nervous system, and heart. The RDA for pregnant women is about 1.
This is a disabling birth defect which is also known as a split spine. We do not know the cause yet, but it is said it can be either environmental or genetic effect. Life Expectancy of Children with Spina Bifida Children who have less mobility are at the risk of metabolic syndrome such as obesity, insulin resistance and hyperlipidaemia as they cannot perform any physical activity in such conditions. Such situations can lead to increased risk of obesity in their adult age. They can be handled by medication but the effects of exercise programs are more effective.
