The cervical region has more white matter because the cervical region works the upper limbs of the body (brachial plexus). In order for our fingers to move quickly, precense of more myelinated axons (white matter) are needed. I hope this is the correct answer to your question.
The cervical region needs more myelinated axons to move your brachial radialis, to move your fingers more quickly.

The spinal cord is enlarged in the cervical and lumbar regions, where the spinal nerves serving the limbs arise.

The parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
the spinal cord is enlarged at the region from where the plexus originate so it is enlarged at the cervical from where the roots for brachial plexus originates the and thoracolumbar level where the cauda equina originates
C 5-8 and 1st thoracic region of your spinal cord pass impulses or messages to your neck, arm and hand muscles. This forms a cervical budge in the cord. Another is found in the lumbar region for the legs.
Cervical Spinal Stenosis is the narrowing of the spinal canal in the neck. The spinal canal is an open area in the bones that make up the spinal column.
ascending (sensory/afferent) and descending (efferent/motor) tracts.Addition: Other than these two types of tracts, the white matter of spinal cord also contains "associative tracts" containing short ascending and descending fibres which coordinate the function of the different regions of spinal cord.
The cervical enlargement occurs at vertebrae C3 through T2 and represents a bulge in the spinal cord that has increased neural input and output to the upper extremities.
The cervical curvature is the most superior spinal curvature.
No. The Spinal cord or column should have nature curvatures. Natural curvature occurs at all 5 regions of the spine (cervical, thoracic, lumbar, sacral and coccygeal region). However, too much curvatures can cause problems, such as scoliosis.
