Explanation:

1. What is the difference between cranial and spinal nerves?

• The main difference between cranial and spinal nerves is that cranial nerves arise from the brain and are distributed in the head, neck, and facial regions areas whereas spinal nerves arise from the spinal cord and are distributed in the other parts of the body such as the skin, skeletal muscles, and blood vessels.

1. What is spinal nerves and cranial nerves?

• Spinal Nerves. The nerves connected to the spinal cord are the spinal nerves. The arrangement of these nerves is much more regular than that of the cranial nerves. All of the spinal nerves are combined sensory and motor axons that separate into two nerve roots.

Answer 2

"CRANIAL NERVES" : Each of twelve pair of nerves which arise directly from the brain not from the spinal cord and pass through separate apertures in skull.
