Thoracic and sacral curves are present at birth also known as primary curves
The thoracic and sacral curves are the primary curves, as they are obvious at birth. The cervical and lumbar curves are secondary as they are modifications on the foetal position.
No, the cervical curvature is considered the secondary curvature, the primary curvatures are the thoracic and sacral curvatures. The lumbar curvature is also considered the Secondary Secondary curvature (yes that's two secondarys, as in the second secondary)

Thoracic and sacral curves are present at birth also known as primary curves
4 curves. two are primary curvatures, because they are present when we are born. they are 1. thoracic 2.sacral other two curves are secondary curvatures. they develop after the birth. 1. cervical , appears when a baby begins to raise its head. 2. lumber , develops when the baby begins to walk. cervical and lumber curvatures are concave in shape and thoracic and sacral curvatures convex in shape.
The primary curve was formed before birth but the secondary curve was formed after birth. Thats basically the difference between the two. hope that helps
nerve cells and spinal column
your two year old was diagnosed with a spinal cord syrinx what is the treatment?
i dont no
There are two main enlargements in the spinal cord, the Cervical enlargement, and an enlargement at the Conus Medullaris in the Thorasic section of the spinal cord.
Not really. The spinal cord runs through the spinal canal, which is anterior (in front of) the spinous processes, betwen two lamina and two pedicles, and posterior (behind) the vertebral body.
