... • In a reflex, our bodies react before our brain is aware of the stimulus. • For example, if we touch a hot object the nerve endings in the skin are stimulated. These nerve endings are the dendrites of the sensory neuron and require a strong stimulus to activate it. The impulse travels along the se ...

... There are an estimated 100 to 180 billion neurons in the nervous system. Each neuron is an individually functioning unit, and yet they all coordinate (or work "in concert") each other. Nerves are made up of long groups of interconnecting neurons. There are many different sizes and shapes of neurons. ...
