Spinal nerves and Cranial nerves

Answer 1

2. Cranial nerve is types of nerves of the peripheral nervous system that connect the muscles and sense organs

Spinal nerves	Cranial nerves
Human body has 31 pairs of spinal nerves.	Human body has 12 pairs of cranial nerves
Spinal nerves originate from the spinal cord	Cranial nerves originate from the brain
All of the spinal nerves are mixed nerves so that each nerve consists of both ventral that is motor and dorsal root that is sensory components.	Except for olfactory, optic, and vestibulocochlear nerves, all other cranial nerves are purely mixed nerves.
