What role does chin tuck play in the pharyngeal phase of swallowing?

• A. It enhances food temperature
• B. It facilitates the swallow reflex
• C. It increases food volume
• D. It aids in mental preparation

Answer: (B)

The role of a chin tuck during the pharyngeal phase of swallowing is primarily to facilitate the swallow reflex. When a person tucks their chin toward their chest while swallowing, it can help to narrow the airway and channel the food down the esophagus more effectively. This action increases the safety of swallowing by helping to protect the airway, which is particularly important for individuals with swallowing difficulties, or dysphagia, as it reduces the risk of aspiration. Tucking the chin may also increase the pressure in the pharynx, which can enhance the swallowing mechanism and ensure that the food or liquid is directed appropriately and efficiently into the esophagus rather than entering the airway. This positioning is a practical strategy used by occupational therapists and speech-language pathologists when working with patients who have compromised swallowing function. It emphasizes the importance of body posture in swallowing mechanics, helping to create a safer and more effective swallowing process.
