what is the function of the soft and hard palate?
The hard palate, which composes two-thirds of the total palate area, is a plate of bone covered by a moist, durable layer of mucous-membrane tissue, which secretes small amounts of mucus. This layer forms several ridges that help grip food while the tongue agitates it during chewing.
The soft palate makes up approximately one third of the posterior portion of the palate its oral mucosal lining is covered with mucous secreting salivary glands. It has no bony frame and is made up entirely of various muscle fibers.
