Reflex Arc is a neural pathway that allows for the rapid and automatic response to a stimulus without conscious thought. It involves a series of events that occur in a specific order.

To draw a flowchart showing the events that occur during sneezing, follow these steps:

1. Start by drawing a rectangle at the top of the page and write "Stimulus" inside it. This represents the trigger that initiates the sneezing reflex.

2. Draw an arrow pointing downwards from the stimulus rectangle and write "Irritation of nasal lining" next to it. This represents the specific stimulus that causes the sneezing reflex, such as dust or allergens irritating the nasal lining.

3. Draw a rectangle below the arrow and write "Sensory Neurons" inside it. This represents the sensory neurons that detect the irritation and transmit the signal to the central nervous system.

4. Draw an arrow pointing downwards from the sensory neurons rectangle and write "Signal transmission" next to it. This represents the transmission of the sensory signal to the spinal cord.

5. Draw a rectangle below the arrow and write "Spinal Cord" inside it. This represents the part of the central nervous system where the reflex arc is processed.

6. Draw an arrow pointing downwards from the spinal cord rectangle and write "Motor Neurons" next to it. This represents the motor neurons that receive the signal from the spinal cord.

7. Draw a rectangle below the arrow and write "Muscles" inside it. This represents the muscles involved in the sneezing reflex, such as the diaphragm and the muscles of the respiratory system.

8. Draw an arrow pointing downwards from the muscles rectangle and write "Contraction" next to it. This represents the contraction of the muscles involved in the sneezing reflex.

9. Finally, draw an arrow pointing downwards from the contraction arrow and write "Sneeze" next to it. This represents the final outcome of the reflex arc, which is the sneezing response.

By following these steps, you can create a flowchart that illustrates the events that occur during sneezing and the reflex arc involved in this process.
