Verified step by step guidance

Understand the components of a reflex arc: A reflex arc typically consists of five main components: receptor, sensory neuron, integration center, motor neuron, and effector.

Identify the role of each component: The receptor detects the stimulus, the sensory neuron transmits the signal to the integration center, the integration center processes the information, the motor neuron carries the response signal, and the effector performs the action.

Focus on the effector: The effector is the part of the reflex arc that responds to the efferent impulses. It is typically a muscle fiber or gland that carries out the response.

Differentiate between the options: The integration center processes the information, the sensory neuron carries signals to the integration center, the motor neuron carries signals from the integration center to the effector, and the receptor detects the stimulus.

Conclude with the correct identification: Based on the roles, the muscle fiber or gland that responds to the efferent impulses is the effector.
