Question: 1 / 400

What does sensation primarily detect?

Changes in temperature

Danger and sends messages to the brain

Sensation primarily detects danger and sends messages to the brain because it is a fundamental function of the nervous system to identify and respond to potentially harmful stimuli. This protective mechanism is crucial for survival, as it allows the body to react swiftly to threats such as injury or environmental hazards. Sensory receptors in the skin, muscles, and organs constantly monitor external and internal conditions, relaying information about pain, temperature, and pressure that can signal danger to the body.

While changes in temperature, signals of pleasure, and movement of the body are also important functions of the sensory system, they are not the primary focus of sensation. The primary role of sensation is to alert the organism to harmful situations, ensuring that appropriate responses can be initiated to protect health and safety.
