- The anatomic relationship between structures
in the oral cavity and pharynx is different than that in adults.
The tongue fills the oral cavity, the fat pads in the cheeks
narrow the oral cavity laterally, and the hyoid bone and larynx
are much higher than in adults, which provides more protection of
the airway. The velum usually hangs lower, with the uvula often
resting inside the epiglottis.
- When sucking from a nipple, the infant
repeatedly pumps the tongue to express milk from the nipple with
each pump collecting liquid at the faucial arches or in the
valleculae. Each infant tends to use a pattern of specific number
of tongue pumps. Normal infants use from 2 to 7 tongue

- The subject in this segment is a 6 month old
male infant. The videofluoroscopy was done due to a suspected
swallowing disorder. The infant's swallowing was in fact normal.
Because swallowing was normal, it was recommended that the child
be assessed for a possible reflux disorder.
