Which of these is the correct path from stimulus to response?
Stimulus is detected by receptors. A signal is sent to the brain. The brain sends a response to the area.
You sense a stimulus. You make a decision to react to the stimulus. A message is sent to the brain. You decide whether to do what your brain tells you.
A stimulus is detected. If the stimulus is severe, your brain reacts. If the stimulus is mild, your brain ignores it. You then make the decision to respond.
A stimulus passes through a chemoreceptor. It then passes to a mechanoreceptor. The signal is then sent to the brain. A photoreceptor causes a response.
