Best answer: Where does the spinal cord terminate?

The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

At which level does the spinal cord terminate?

The spinal cord terminates in the lumbar spine. The exact point of termination varies among individuals; most commonly, it terminates at the level of the L1 or L2 vertebrae.

Where does the spinal cord end in a fetus?

During normal fetal development, the conus medullaris (CM), which is situated at the sacral region of the vertebral column, ascends to its final location at birth proximal to the L2 vertebra7; however, the precise timing of this ascent is unknown and disputable, and the literature provides controversial data.

Why does the spinal cord end at L2?

Although the spinal cord cell bodies end around the L1/L2 vertebral level, the spinal nerves for each segment exit at the level of the corresponding vertebra. For the nerves of the lower spinal cord, this means that they exit the vertebral column much lower (more caudally) than their roots.

Individuals born with spina bifida (myelomeningocele) face serious physical and social consequences, including paralysis, insensate skin, and potential social ostracism associated with loss of bowel and bladder control. Over time, muscle paralysis can produce contractures, joint dislocations, and spinal deformity.

What are the chances of having a second baby with spina bifida?
