The correct Answer is:
To solve the question, we need to identify the appropriate words to fill in the blanks related to the function of afferent neurons in the nervous system. ### Step-by-Step Solution: 1. **Understanding Afferent Neurons**: Afferent neurons, also known as sensory neurons, are responsible for receiving signals from sensory organs. These neurons carry information from the peripheral nervous system to the central nervous system. 2. **Identifying the Source of Signals**: The first blank requires a term that indicates where the afferent neuron receives its signals from. Since afferent neurons receive signals from sensory organs, we can fill in the first blank with "sensory organ". 3. **Understanding Impulse Transmission**: The second blank pertains to how the impulse is transmitted into the spinal cord. Afferent neurons transmit impulses through specific structures. In this case, the impulses travel via the dorsal root ganglion, which is a cluster of nerve cell bodies (soma) located near the spinal cord. 4. **Filling in the Blanks**: Based on the understanding from the previous steps, we can fill in the blanks as follows: - The afferent neuron receives signal from a/an **sensory organ** and transmits the impulse via a **dorsal root ganglion** into the spinal cord. 5. **Final Answer**: The complete statement is: "The afferent neuron receives signal from a/an **sensory organ** and transmits the impulse via a **dorsal root ganglion** into the spinal cord."
