How would you describe spina bifida?
Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way.
What does occulta mean?
Occulta = Latin: “hidden.” (Unlike in “open” spina bifida, the defect in spina bifida occulta is not visible.) Spina bifida occulta is a malformation of one or more vertebrae (bones of the spine). It is sometimes called “closed” spina bifida.
What is the pathophysiology of spina bifida?
This congenital pathology is caused by the maldevelopment of the ectodermal, mesodermal, and neuroectodermal tissues. The spina bifida is a congenital anomaly that arises from incomplete development of the neural tube. It is commonly used as a nonspecific term referring to any degree of neural tube closure.
What is the meaning of Meningomyelocele?
Myelomeningocele is a birth defect in which the backbone and spinal canal do not close fully before birth. The condition is a type of neural tube defect (NTD).
What is spina bifida caused by?
Doctors aren’t certain what causes spina bifida. It’s thought to result from a combination of genetic, nutritional and environmental risk factors, such as a family history of neural tube defects and folate (vitamin B-9) deficiency.
What causes spina bifida occulta?
Environmental risk factors for spina bifida include maternal folate deficiency very early in pregnancy, maternal health conditions like diabetes or obesity, and maternal use of certain medications early in pregnancy.
Where does spina bifida occulta occur?
Spina bifida occulta (SBO) is a common malformation of the spine. It occurs during a baby’s development in its mother’s womb, usually in the first month of pregnancy. In people with this condition, the bones of the spine, called vertebrae, don’t properly close.
What kind of mutation causes spina bifida?
The team found that when the mutated Vangl2 gene was present in just 16% of developing spinal cord cells, spina bifida occurred. Their results indicate that the cellular signalling process is surprisingly vulnerable to uninheritable mosaic mutations.
What is spina bifida PDF?
Definition: Spina bifida is a birth defect that falls under the category of neural tube defects. The neural tube is the embryonic structure that eventually develops into the baby’s brain and spinal cord and the tissues that enclose them.
What chromosome causes spina bifida?
The best-studied of these genes is MTHFR, which provides instructions for making a protein that is involved in processing the vitamin folate (also called vitamin B9). A shortage (deficiency) of this vitamin is an established risk factor for neural tube defects like spina bifida.
