The earthworm's main nerve cord is located on its belly and runs along the length of its body, whereas humans have a central nervous system composed of the brain and spinal cord. The earthworm's nerve cord is simpler and coordinates basic reflex responses, while the human central nervous system is more complex and involved in higher brain functions.

While humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side. The nerve cord of an earthworm relays impulses from receptors in the worm's anterior to posterior parts of its body.
The main nerve that runs through the body is the spinal cord. It extends from the brain down the back and is responsible for transmitting signals between the brain and the rest of the body. Branching off the spinal cord are peripheral nerves that extend to different parts of the body.
This syndrome results from pressure that compresses the ulnar nerve. The ulnar nerve is one of the main nerves of the hand, which connects the muscles of the forearm and hand with the spinal cord.

Sciatic Nerve.
The cerebral peduncles are located in the midbrain, which is part of the brainstem. They serve as the main motor pathway for nerve impulses traveling from the cerebral cortex to the spinal cord.
