Cervical Enlargement: Understanding the Widest Part of Your Spinal Cord

The widest part of the spinal cord is called the cervical enlargement.

This enlargement is associated with the origin of the nerves that control the upper limbs and is therefore larger in diameter compared to other segments of the spinal cord.
