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 of the spinal cord has more white matter because it is responsible for relaying information between the brain and the rest of the body, requiring a higher volume of nerve fibers for communication. This white matter consists of myelinated axons that facilitate fast transmission of signals, crucial for coordinating voluntary movements and sensory information in the upper body.

Cervical spinal stenosis is a narrowing of the spinal canal in the neck region, which can put pressure on the spinal cord and nerves. This can lead to symptoms such as neck pain, weakness, numbness, or tingling in the arms or hands. Severe cases may require surgical intervention to relieve pressure on the spinal cord.
The parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
There is more white matter at the cervical level compared to the sacral level because the cervical region has a higher concentration of ascending sensory pathways traveling from the body to the brain. These pathways require more white matter for transmission of these sensory signals. Additionally, the cervical region has a larger proportion of corticospinal tracts responsible for motor control, which also contribute to the increased white matter volume.
The disease Cervical Myelopathy is classified as a dysfunction of the spinal cord. As result, there can be multiple sources for Cervical Myelopathy, which include cervical stenosis, herniated discs, and sclerosis.
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.
The spinal column is divided into five main sections: the cervical, thoracic, lumbar, sacral, and coccygeal regions. The cervical region consists of seven vertebrae (C1-C7), the thoracic region has twelve (T1-T12), the lumbar region contains five (L1-L5), the sacral region is made up of five fused vertebrae (S1-S5), and the coccygeal region typically has four fused vertebrae forming the coccyx. Each section serves different functions and supports various parts of the body.
The thoracic region of the spinal cord lacks autonomic preganglionic neurons. Autonomic preganglionic neurons are found in the intermediolateral cell columns of the spinal cord at the thoracolumbar (T1-L2) and sacral (S2-S4) levels.
The lumbar enlargement is a region of the spinal cord that exhibits a widening in the lower back area. It serves as the main site for the spinal nerves that innervate the lower limbs. This enlargement is responsible for the increased nerve activity associated with controlling and coordinating movements of the legs and pelvis.
