Imagine a dog steps on a pin and pulls its foot away. Look at the reflex arc of this scenario below. Which of the following statements best describes the image?
O The brown circle A shows neurotransmitters being released, and the blue circle B shows neurotransmitters being
absorbed.
The brown circle A is an effector, and the blue circle B is a receptor.
The brown circle A is a receptor, and the blue circle B is an effector.
The brown circle A shows neurotransmitters being absorbed, and the blue circle B shows neurotransmitters being
released.

The brown circle A is a receptor, and the blue circle B is an effector.

Explanation:

The brown circle indicates a receptor whereas the blue circle is an effector because brown circle have sensory cells which receives the sensation due to pins into the foot and this information is taken to the central nervous system through sensory neurons while on the other hand, blue circle is an effector to which instructions comes from the central nervous system through motor neurons and as a result the dog pulls away its foot from the region where pin is placed.

C. The brown circle A is a receptor, and the blue circle B is an effector.
