Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1]
The effect of pregnancy on platelet count is unclear, with some studies demonstrating a mild decline in platelet count and other studies that show no effect. [24] The white blood cell count increases with occasional appearance of myelocytes or metamyelocytes in the blood. [24] During labor, there is a rise in leukocyte count.

During pregnancy, the enlarged abdomen and gravid uterus place additional strain on lumbar muscles and shift the pregnant woman's center of gravity. These postural compensations culminate in an increased load on both lumbar spinal musculature and the sacroiliac ligaments, manifesting as low back pain and/or pelvic girdle pain. [14]
The CSF-filled central chamber is continuous from the telencephalon to the spinal cord, and constitutes the developing ventricular system of the CNS. Because the neural tube gives rise to the brain and spinal cord any mutations at this stage in development can lead to fatal deformities like anencephaly or lifelong disabilities like spina bifida.
Lumbarization is an anomaly in the spine. It is defined by the nonfusion of the first and second segments of the sacrum. The lumbar spine subsequently appears to have six vertebrae or segments, not five. This sixth lumbar vertebra is known as a transitional vertebra. Conversely the sacrum appears to have only four segments instead of its ...
In the first scenario, it can be due to a genetic condition, trauma to the spine, pregnancy in women, increased abdominal fat, or a sedentary lifestyle (sitting too much causes muscle imbalances and is the most common reason for this issue) and in the second scenario, the estrogen weakens the muscles in the area.
