There are three kinds of neurons in your body. These neurons are sensory neurons, inter-neurons, and motor neutrons.
1 Sensory neutrons pick up stimuli from the environment and converts it into a nerve impulse. The nerve impulse travels along the sensory neuron until it reaches an inter-neuron.
2 Inter-neurons carry nerve impulses from one neuron to another neutron. Sometimes inter-neutrons pass impulses from sensory neurons to motor neutrons.
3 Motor neutrons send an impulse to a muscle, and then the muscle reacts.
