The intrinsic and extrinsic muscles of the tongue continue the action initiated in the oral phase.
These observations underline the importance of cortical and cognitive input to the oral phase of swallowing.
Sensory input is critical to the oral phase of swallowing, because assessment of the chemical and physical properties of the bolus at this point allows ready expulsion of boluses with noxious properties.
Several muscle groups participate in the oral phase of swallowing (Tables 1, 2, 3, 4, 5, 6).
Afferent sensory neurons important in the oral phase of swallowing travel in CNs V, VII, IX, and XI (Figure 5).
Tachimura T, et al. Change in palatoglossus muscle activity in relation to swallowing volume during the transition from the oral phase to the pharyngeal phase.
These muscles act during the oral phase of deglutition to stiffen the soft palate, lower the soft palate to prevent premature bolus spill into the pharynx, or elevate the soft palate to open the oral cavity posteriorly.
Because of the large degree of cortical input to the oral phase of swallowing, little information exists regarding the receptive fields and sensory stimuli that facilitate the onset of oral transport.
The salivary glands are essential for normal bolus formation during the oral phase of swallow, adding moisture and lubrication to the chewed material prior to the initiation of the pharyngeal phase of swallow.
The identities of the candidates, and thus their genders, are only disclosed during the oral phase.
They jumped from the oral phase to this phase".
