Everything about The Soft Palate totally explained
The
soft palate (or
velum, or
muscular palate) is the soft
tissue constituting the back of the roof of the
mouth. The soft palate is distinguished from the
hard palate at the front of the mouth in that it doesn't contain bone.
Function
It is movable, consisting of
muscle fibers sheathed in
mucous membrane, and is responsible for closing off the
nasal passages during the act of
swallowing.
The soft palate's motion during breathing is responsible for the sound of
snoring. Touching the soft palate evokes a strong
gag reflex in most people.
The soft palate retracts and elevates during speech to separate the oral cavity (mouth) from the nasal cavity in order to produce the oral speech sounds. If this separation is incomplete, air escapes through the nose, causing the speech to be perceived as hypernasal.
while sneezing it protects nasal passage by diverting a part of substance to be thrown out to mouth.
