Final answer:
The name of the curved portion of the vertebrae between the transverse process and the spinous process is called the lamina.
Step-by-step explanation:
The curved portion of the vertebrae located between the transverse process and the spinous process is called the lamina. The lamina is part of the vertebral arch and serves to complete the enclosure in which the spinal cord is housed. This structure serves as a connection point between the more laterally situated transverse processes and the midline-oriented spinous process, providing structural integrity to the vertebral arch and serving as an attachment point for muscles and ligaments. The curved portion of the vertebrae located between the transverse process and the spinous process is called the lamina.
