Because by the sacral level, most descending tracts have already exited the spinal column.
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.
The white matter is located on the outside of the gray matter in the spinal cord.
White matter appears white in the brain because it is made up of nerve fibers covered in a fatty substance called myelin. Myelin reflects light, giving white matter its white color.
The hippocampus is primarily composed of gray matter, which consists of cell bodies, dendrites, and synapses. White matter, on the other hand, is made up of myelinated axons.
The corpus callosum is composed of white matter.
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 parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
The cervical region of the spinal cord contains the most white matter. This is primarily due to the presence of ascending and descending nerve fibers that carry sensory and motor information between the brain and the rest of the body. As you move down the spinal cord to the thoracic and lumbar regions, the amount of white matter decreases while the gray matter increases, reflecting the local processing of information in those areas.

It is superficial to the white matter.

The white fluid in the uterus is called the cervical fluid. It changes throughout the menstrual cycle and is a primary fertility sign.
The white matter consist of myelinated nerve fibers.
Gray matter doesn't fit. White matter is white because it has myelin covering the axons. And the myelin fiber tract is "white" for the same reason.
White Fang is generally considered to be suitable for readers at a middle school reading level. The vocabulary and themes in the book are accessible to young readers, but the content may still be challenging due to the complex emotions and subject matter.
