Why does the cervical region of the spinal cord have more white matter than the other regions of spinal cord?
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.

Why does the cervical region of the spinal cord have more white matter than other regions?
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.
Muscles of the neck and shoulder are innervated by spinal nerves from what region?
Cervical region
What is the medical term meaning nerve pain caused by pressure on the spinal nerve roots in the neck region?
cervical radiculopathyradiculopathyCervical radiculopathyCervical radiculopathy
What is Cervical Spinal Stenosis?
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.
What are the part of spinal cord?
The parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
Why is there more white matter at the cervical level than at the sacral level?
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.
What disease is cervical myleopathy?
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.
What two regions is the spinal cord enlarged?
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
What is the bulge in spinal cord containing cell bodies of motor neurons supplying upper limb?
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.
How many sections is the spinal column broken in to?
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.
Which spinal region lacks autonomic preganglionic neurons?
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.
What is lumbar enlargement?
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.
