Jakeluputkeen, also known as the "sneeze reflex," is a physiological response that occurs when irritants or allergens enter the nasal cavity. This reflex is triggered by the stimulation of sensory neurons in the nasal mucosa, which send signals to the brain via the trigeminal nerve. The brain then initiates a series of events that result in a sudden, forceful expulsion of air from the lungs, commonly known as a sneeze.

The sneeze reflex serves several purposes. It helps to clear the nasal passages of irritants, allergens, or other foreign substances, thereby protecting the respiratory system from potential infections or damage. Additionally, sneezing can help to disperse airborne pathogens, reducing the risk of transmission to others.

The mechanics of a sneeze involve the rapid closure of the glottis (the space between the vocal cords), which prevents air from escaping through the mouth. This closure is followed by a sudden increase in intra-thoracic pressure, forcing air out of the lungs through the nose. The force of the sneeze can be quite powerful, with some individuals capable of generating pressures exceeding 100 mmHg.

The sneeze reflex is a well-studied phenomenon in physiology and has been the subject of numerous scientific investigations. However, the exact mechanisms underlying the reflex remain an area of ongoing research. Factors such as individual anatomy, the nature of the irritant, and the timing of the reflex can all influence the force and duration of a sneeze.
