What is lumbar enlargement?
The spinal cord is enlarged in the cervical and lumbar regions, where the spinal nerves serving the limbs arise.
What is Cervical Spinal Stenosis?
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.
How many bones are their in a human vertibral column?
There are 33 bones in the spinal column. There are five regions in the column. In descending order there is the Cervical region which has 7 bone, Thoracic region which has 12 bones, Lumbar region which has 5 bones, Sacral region which has 5 bones (these bones are fused together), and the Coccygeal region that has 4 bones (these bones are fused together). The coccygeal region can actually have anywhere from 3-5 bones, but the average is 4.
What is the significance of the cervical and the lumbar regions?
They are sections of the spine. They are used in medical terminology to distinguish between the four areas of the spine and back: the cervical region (neck), the thoracic region (upper torso/shoulder blade area), the lumbar region (waist/low back area) and the sacral/coccygeal region (lowest part of back and tail bone/coccyx).It is often in these two areas, the cervical and the lumbar, areas that people have injuries, strains, sprains, and chronic pain. The cervical area is where whiplash occurs and the lumbar and lumbo-sacral areas are the most common regions for low back injuries and pain.
Why is there more white matter at the cervical level than at the sacral level?
Because by the sacral level, most descending tracts have already exited the spinal column.
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.
Which spinal region lacks autonomic preganglionic neurons?

What is lumbar enlargement?

What is the medical term meaning nerve pain caused by pressure on the spinal nerve roots in the neck region?

What are the part of spinal cord?
The parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
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.
What is Cervical Spinal Stenosis?
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.
What two tracts do the spinal cord have?
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.
What causes the cervical enlargement of the 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.
Which spinal curvature is the most superior one?
The cervical curvature is the most superior spinal curvature.
