What two regions is the spinal cord enlarged?

Answer 1

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

Answer 2

The spinal cord enlarges at the cervical and lumbosacral areas in order to accomodate the extra neurons involved with the motor control going to, and sensations coming from, the upper and lower limbs.
In the cervical spine, the neurons involved with upper limb motor control and sensory reception are found, and in the lumbosacral spine, these extra neurons can be found for the lower limbs. The thoracic and upper lumber spinal cord does not have the "extra" neurons associated with peripheral limb motor control and sensation making this area smaller.

Answer 3

The spinal cord enlarges in two places:

1. In the cervical area (C5-T1) which is where the brachial plexus (a large group of nerves which provide the nervous supply to the arms and some of the chest) extends from.
2. The Lumbosacral area (L2-S3) which is where the lumbosacral plexus ( a large group of nerves which provide the nervous supply to the lower part of the body) extends from

Answer 4

The spinal cord is enlarged in the cervical and lumbar regions.

Answer 5

cervical enlargement and lumbar enlargement

Answer 6

The cervical region of the spinal cord corresponds to the large nerves of the upper limbs. The cervical enlargement is due to the neutral input and output of those upper limbs.

Answer 7

The cord is wider at the area of nerves serving the arms and again at the legs.

Answer 8

cervical and lumbar

Answer 9

the lumbar and cervical regions
