What is the second source for sensory nerve firing?

• A. Gravity
• B. Animal's senses
• C. Temperature
• D. Pressure

Answer: (B)

Sensory nerve firing starts when receptors are stimulated and convert that stimulation into nerve impulses. Physical cues like gravity, temperature, and pressure are classic stimuli that can trigger firing through their respective receptors. The second source here is the animal’s senses themselves—the sensory organs and their receptors that detect and translate environmental information into neural signals. In short, the animal’s senses provide the neural input that drives sensory nerve firing after the initial environmental cues are perceived.
