What does the sensory nerve detect?

1. Contractions

2. Movements

3. Signals for reflexes

4. Temperature changes

The correct answer is: Contractions

Sensory nerves are responsible for collecting and transmitting information from our senses. This includes physical sensations like touch, pain, and temperature changes. Option A, contractions, does not fall under the category of sensory information. Option B, movements, can be detected by other types of nerves like motor nerves and proprioceptive nerves. Option C, signals for reflexes, involves a combination of sensory and motor nerves. Option D, temperature changes, is in fact included in the sensory information detected by sensory nerves, but it is not the only thing they detect. Therefore, option A is the best answer because it is the most specific and directly related to the function of sensory nerves.
