Which of the following best describes the function of exteroceptors in the sensory system?
A
They monitor the internal environment, such as blood pressure and pH.
B
They transmit motor commands from the brain to the muscles.
C
They are responsible for detecting muscle stretch and joint position.
D
They detect stimuli originating from outside the body, such as light, sound, and temperature.
Verified step by step guidance1
Understand the term 'exteroceptors': Exteroceptors are specialized sensory receptors that detect stimuli originating from outside the body, such as light, sound, temperature, and touch.
Differentiate exteroceptors from other types of sensory receptors: For example, interoceptors monitor the internal environment (e.g., blood pressure and pH), while proprioceptors detect muscle stretch and joint position.
Analyze the options provided in the question: Eliminate choices that describe functions unrelated to exteroceptors, such as monitoring internal conditions or transmitting motor commands.
Focus on the correct description of exteroceptors: They are responsible for detecting external stimuli, which aligns with the correct answer provided in the question.
Conclude that the correct answer is: 'They detect stimuli originating from outside the body, such as light, sound, and temperature,' based on the definition and function of exteroceptors.
