Final answer:
Proprioceptive sensors vs. exteroceptive sensors and passive sensors vs. active sensors explained.
Step-by-step explanation:
Proprioceptive sensors and exteroceptive sensors are two types of sensory receptors. Proprioceptive sensors are located near moving parts of the body, such as muscles, and interpret the positions of tissues as they move. Exteroceptive sensors, on the other hand, are located near stimuli in the external environment, such as somatosensory receptors in the skin that detect touch, temperature, and pressure.
Passive sensors and active sensors are two types of sensory systems. Passive sensors detect stimuli without actively producing a signal, such as the somatosensory receptors in the skin that detect touch. Active sensors, on the other hand, actively emit a signal and measure its reflection to detect stimuli, such as the sonar used by some animals to detect objects in their environment.
