| Sensory Neuron (Carries Signal to Spinal Cord) |
| ↓ |
| Spinal Cord (Processing Center) |
| ↓ |
| Motor Neuron (Carries Signal to Effector) |
| ↓ |
| Effector (Muscles Involved in Sneezing Diaphragm, Chest and Abdominal Muscles) |
| ↓ |
| Response (Sneezing) |
Path of a Reflex Action - Sneezing:
- Stimulus: Presence of an irritant in the nasal passage.
- Sensory Receptor: Nasal nerve endings detect the irritant.
- Sensory Neuron: Carries the sensory signal to the spinal cord.
- Spinal Cord: Acts as the processing center for the reflex action.
- Motor Neuron: Carries the processed signal from the spinal cord to the effector.
- Effector: Muscles involved in the sneezing reflex, including the diaphragm, chest, and abdominal muscles.
- Response: Sneezing occurs as a rapid and involuntary expulsion of air to clear the irritant from the nasal passage.
