Question

who has better developed reflex action, animal or human and why

Answer 1

animal has better reflex because they need to survive among predators and nature

Answer 2

It is partially to do with the distance the nerve signal has to traverse, but the nerve fibre makes a big difference. The nerve fibres (axons) responsible for a cat's reflexes are quite thick compared with humans, which means faster nerve transmission (i.e. the signals to the muscles travel faster).

animals have faster than human
