Questions: What Functions to Detect changes Inside and Outside of the Body? What functions to detect changes inside and outside of the body? Multiple Choice Central nervous system Sensory receptors Neuroglia Effectors

The answer is the second one (B): Sensory receptors.

Explanation for each option:

1. Central nervous system (CNS): The CNS, which includes the brain and spinal cord, processes information and coordinates responses but does not directly detect changes. It relies on sensory receptors to gather information about changes inside and outside the body.

2. Sensory receptors: Sensory receptors are specialized cells or nerve endings that detect changes in the environment (both internal and external) and send this information to the CNS for processing. They are responsible for sensing stimuli such as temperature, pain, pressure, and light.

3. Neuroglia: Neuroglia, or glial cells, support and protect neurons in the nervous system but do not detect changes themselves. They play roles in maintaining homeostasis, forming myelin, and providing support and protection for neurons.

4. Effectors: Effectors are muscles or glands that respond to signals from the nervous system to produce a response or action. They do not detect changes but rather act upon the information received from the CNS.

Summary: Sensory receptors are the correct answer because they are the structures responsible for detecting changes inside and outside of the body and relaying this information to the central nervous system for processing.
