What is the difference between a frog and a human nervous system?

The frog's nervous

system consists of a brain, a spinal cord, and nerves. Frogs have a

highly developed sense of hearing; they can detect high-pitched

sounds with their ears and low-pitched sounds through their skin.

Moreover, the frogs don't have an external ear like humans do which

contributes to maintain body balance. They also have a highly

developed sense of sight and smell; its sense of smell is

registered by olfactory lobes. These make up the forward portion of

the brain. This allows frogs to become aware of predators and prey

using their large eyes that project from their head. The eyes are

fixed lens, they cannot change its focus. In addition, they have a

poorly developed eyelids that do not move. To close its eye, the

frog draws the eye into its socket. Frogs also have a keen sense of

smell to detect chemical signals that help them identify potential

food.
