Explanation The two bulges are attached to the upper and lower limbs and are present in cervical and lumbar regions, respectively. The nerve roots that form spinal nerves serve the limbs attached to these bulges. These two bulges of the spinal cord are as follows: 1. Cervical enlargement: The bulge that is present in the cervical region is known as cervical enlargement. It makes the attachment of large nerves with the upper limbs. It starts from the fifth cervical vertebrae to the first thoracic vertebrae...
