Final answer:
Sensory receptors can be classified into six groups based on the type of stimuli that activate them, including chemoreceptors, photoreceptors, thermoreceptors, mechanoreceptors, nociceptors, and proprioceptors.
Step-by-step explanation:
The receptors can be classified into six groups based on the type of stimuli that activate them:
Chemoreceptors: These receptors respond to chemical stimuli and are involved in sensing taste and smell.
Photoreceptors: These receptors are sensitive to light and are found in the eyes, allowing us to see.
Thermoreceptors: These receptors detect changes in temperature and help us sense hot and cold.
Mechanoreceptors: These receptors respond to mechanical stimuli such as pressure, vibration, and touch.
Nociceptors: These receptors are responsible for sensing pain and are activated by intense stimuli like tissue damage.
Proprioceptors: These receptors are found in muscles, tendons, and joints and provide information about body position and movement.
