What causes the lumbar enlargement of the spinal cord?
The lumbar enlargement of the spinal cord corresponds to the mild increase in cross sectional area of the cord from the T11 level to the conus medullarisconus medullarisThe conus medullaris (Latin for "medullary cone") or conus terminalis is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower.https://en.wikipedia.org › wiki › Conus_medullarisConus medullaris - Wikipedia. It is enlarged due to the presence of the spinal nerve anterior rami which contribute to the lumbar and sacral plexuses.
What is the function of the cervical?
Your cervical spine consists of the first seven vertebrae in your spine. It provides support for the weight of your head, surrounds and protects your spinal cord, and allows for a wide range of head motions.
Why does the cervical enlargement occur?
As the spinal cord is shorter in length than the vertebral column, it extends from the C3 to T1/T2 vertebral levels, its greatest circumference (approximately 38 mm) at the C6 level. The cervical enlargement is a result of the increased volume of motor cells in the ventral horns of the grey matter.
What Is Cervical Enlargement? What Does Cervical Enlargement Mean?
Where is cervical enlargement of spinal cord?
Two enlargements of the spinal cord can be visualized: The cervical enlargement, which extends between C3 to T1; and the lumbar enlargements which extends between L1 to S2 (Figure 3.1). The cord is segmentally organized.
What causes cervical enlargement?
As the spinal cord is shorter in length than the vertebral column, it extends from the C3 to T1/T2 vertebral levels, its greatest circumference (approximately 38 mm) at the C6 level. The cervical enlargement is a result of the increased volume of motor cells in the ventral horns of the grey matter.
Why is there cervical enlargement in the spinal cord?
Two regions of the spinal cord are enlarged to accommodate the greater number of nerve cells and connections needed to process information related to the upper and lower limbs (see Figure 1.10B).

What is the main function of the cervical?
Your cervical spine consists of the first seven vertebrae in your spine. It provides support for the weight of your head, surrounds and protects your spinal cord, and allows for a wide range of head motions.
What is the significance of the two enlargements of the spinal cord?
Two regions of the spinal cord are enlarged to accommodate the greater number of nerve cells and connections needed to process information related to the upper and lower limbs (see Figure 1.10B).

What is the significance of cervical and lumbar enlargements?
The cervical and lumbar regions of the spinal cord show a larger diameter compared to the rest of the regions. The cervical enlargement and lumbar enlargement represent an increased amount of neurons in the gray matter and axons in the white matter that serve the upper limbs and lower limbs, respectively.
What is an enlarged spinal cord?
The lumbar enlargement (or lumbosacral enlargement) is a widened area of the spinal cord that gives attachment to the nerves which supply the lower limbs.
