We call the major salivary glands the parotid, submandibular, and sublingual glands. They all secrete saliva into your mouth, the parotid through tubes that drain saliva, called salivary ducts, near your upper teeth, submandibular under your tongue, and the sublingual through many ducts in the floor of your mouth.esides these glands, there are many tiny glands called minor salivary glands located in your lips, inner cheek area (buccal mucosa), and extensively in other linings of your mouth and throat. Salivary glands produce the saliva used to moisten your mouth, initiate digestion, and help protect your teeth from decay.

Suborbital research missions are launched from NASA Goddard Space Flight Center's Wallops Flight Facility on Virginia's Eastern Shore. NASA also has secondary launch sites at Kodiak Island, Alaska, and the Kwajalein Atoll in the Republic of the Marshall Islands.hen a launch is postponed, or scrubbed, during the countdown, the nature of the problem determines how long the delay will last. Schedule changes are a normal part of the space business and reflect a commitment to launch safety.
