Receptors are parts of the nervous system that allow it to:

• A. Transmit electrical impulses to muscles for movement
• B. Detect and respond to stimuli from the environment
• C. Store genetic information for cell reproduction
• D. Produce hormones that regulate metabolism

Answer: (B)

Verified step by step guidance

1. Understand the role of receptors in the nervous system: Receptors are specialized cells or structures that detect changes or stimuli in the environment, such as light, sound, touch, or chemical signals.
2. Recognize that receptors convert these environmental stimuli into electrical signals, a process known as transduction, which allows the nervous system to process information.
3. Note that receptors do not transmit impulses directly to muscles; instead, they send signals to the nervous system, which then coordinates muscle movement.
4. Differentiate receptors from other biological components: storing genetic information is the role of DNA within cells, and hormone production is carried out by endocrine glands, not receptors.
5. Conclude that the primary function of receptors is to detect and respond to stimuli from the environment, enabling the nervous system to perceive and react appropriately.
