Humans have a spinal cord down the dorsal surface of their back.
Grasshoppers have a nerve ladder down the ventral surface of their belly.
Carry a nerve impulse to the next nerve OR to an effector cell.
Grasshopper
Carry a nerve impulse to the next nerve OR to an effector cell.
The nervous system of a hydra is decentralized and consists of a simple nerve net without a central brain, allowing for basic reflexive movements and responses to stimuli. In contrast, a grasshopper has a more complex, centralized nervous system featuring a brain and a ventral nerve cord with ganglia, enabling more coordinated movements and advanced behaviors. This difference reflects their varied lifestyles, with the hydra being a simple aquatic organism and the grasshopper being a more mobile terrestrial insect. Overall, the structural complexity of the grasshopper's nervous system supports greater behavioral versatility compared to the hydra.
how nerve cell differ show description
i dont think itll differ as nerve cells donot differ according to the size of the organism
the optic nerve
Yes, the sciatic nerve is the largest nerve in the human body.
sciatic nerve
The cochlea is the part of the human that contains the auditory nerve
Nerve Cells are capable of transmitting [relaying] bio-information.
It runs along the dorsal side of the body.
