Given below are five groups of terms. In each group arrange and rewrite the terms in the correct order so as to be in a logical sequence.
For example:
Question : Implantation, Parturition, Ovulation, Gestation, Fertilization.
Answer: Ovulation, Fertilization, Implantation, Gestation, Parturition.
Spinal cord, Motor neuron, Receptor, Effector, Sensory neuron.

Explanation

To arrange the terms in a logical sequence, we need to understand the flow of information in the nervous system. Here’s the step-by-step solution:

1. **Receptor**: The process starts with a receptor, which is a specialized cell that detects a stimulus (such as light, sound, or touch) and converts it into an electrical signal (nerve impulse).

2. **Sensory Neuron**: The electrical signal generated by the receptor is then transmitted to a sensory neuron. This neuron carries the impulse from the receptor to the spinal cord.

3. **Spinal Cord**: Once the sensory neuron transmits the impulse to the spinal cord, the spinal cord processes the information and generates a response by sending out motor impulses.
