Submucosal glands can refer to various
racemose exocrine glands of the
mucous type. These glands secrete
mucus to facilitate the movement of particles along the body's various tubes, such as the throat and intestines. The mucosa is the lining of the tubes, like a kind of
skin.
Submucosal means that the actual gland resides in the connecting tissue below the mucosa. The submucosa is the tissue that connects the mucosa to the
muscle outside the tube.
