Question

why are reflex arc developed in animals

Answer 1

A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron. As a result, one of your muscles or glands is stimulated.
In order to perform quick response or actions sensory neurons do not connect directly to the brain, instead they meet in the spinal cord. Reflex arc, have evolved in animals, in order to perform quick responses, as the thinking process of brain is not fast enough.
