Answer 1

Do you have a guess?

Answer 2

The dorsal root contains sensory fibers that control information like pain and temperature sensations, while the ventral root is made up of motor fibers that send electrochemical signals to the body’s muscles and glands. These impulses control the following:

Muscular contractions
Hormone synthesis
Gland secretion

As for in the case of Lumbar Nerve 1, it innervates:

Quadratus lumborum
Iliopsoas muscle

Which means your lower body's movement will be affected. :D
