Sublingual nitroglycerin
Its called the Frenulum or AKA the Tongue Web.
sublingual
The tongue
Literally: 'under tongue' If you have to take a pill or some type of other medication (nitro perhaps) sublingually, you place it underneath your tongue and let it dissolve.
One tablet of this type is nitroglycerin, a vasodialator (expands blood vessels), that is placed under the tongue, and absorbed this way, rather than by chewing or swallowing. This type of medication is called a sublingual tablet (meaning "under the tongue").
sublingually (under tongue) A Doctor will prescribe a sub-lingual or Buccal administered drug when there is a need for the medication to be absorbed rapidly. The cheek and under the tongue areas have a lot of capillaries which means that the medication will go directly into the bloodstream.
Sublingual refers to a method of administering medication by placing it under the tongue, where it is absorbed directly into the bloodstream. This route bypasses the digestive system and can lead to faster onset of action compared to swallowing a pill.
Sublingual medications should typically be held under the tongue for about 1 to 5 minutes, depending on the specific medication. This allows for optimal absorption through the mucous membranes. It's important to follow the instructions provided with the medication or consult your healthcare provider for guidance.
If it's anything medical, then SL means sublingual(under the tongue) and TID means three times. So a patient would take their medication under the tongue three times a day.

The connective tissue under the tongue that connects the tongue to the bottom of the mouth is called the lingual frenulum. It helps to support and stabilize the movement of the tongue during activities such as speaking and eating.
