Verified step by step guidance

Understand the components of a feedback system: A feedback system typically consists of a receptor, a control center, and an effector.

Identify the role of an effector: An effector is the component that carries out the response to bring about a change in the system, usually to maintain homeostasis.

Consider the options provided: Cerebral cortex, Hypothalamus, Skeletal muscle, Sensory neuron.

Analyze each option: The cerebral cortex and hypothalamus are parts of the brain involved in processing information and regulating bodily functions, but they are not effectors. Sensory neurons are responsible for transmitting signals to the control center, not acting as effectors.

Recognize the correct effector: Skeletal muscle is a typical effector in a feedback system as it can contract and produce movement or generate heat, thereby effecting change in the body.
