The area under the tongue is called the floor of the mouth, primarily featuring the frenulum and sublingual region.
Understanding The Area Under The Tongue- What Is It Called?
The area under the tongue, often overlooked, plays a crucial role in oral health and function. This region is anatomically known as the floor of the mouth. It encompasses several important structures, including the lingual frenulum, sublingual glands, blood vessels, and muscles that aid in speech, swallowing, and salivation.
The lingual frenulum is a thin fold of mucous membrane that connects the underside of the tongue to the floor of the mouth. This structure helps stabilize the tongue while allowing sufficient mobility for speech and eating. Just beneath this frenulum lies a rich network of blood vessels and nerves essential for oral sensation and function.
Additionally, the floor of the mouth houses two major salivary glands called sublingual glands. These glands secrete saliva directly into this area through multiple small ducts known as Rivinus ducts. Saliva here aids digestion and maintains oral hygiene by keeping tissues moist and flushing away bacteria.
This region’s anatomy is delicate but vital. Any abnormalities or injuries to this area can impact speech clarity, swallowing efficiency, or even cause discomfort during everyday activities like eating or speaking.
Key Anatomical Features of the Area Under The Tongue
The Lingual Frenulum
The lingual frenulum is a thin strip of tissue running from the bottom center of your tongue to the floor of your mouth. Its length and elasticity vary among individuals. In some cases, an unusually short or tight frenulum can cause a condition called ankyloglossia (commonly known as “tongue-tie”), which restricts tongue movement.
This condition may affect infants’ ability to breastfeed or cause speech difficulties later in life if untreated. Surgical procedures like frenectomy are often performed to release this restriction.
Sublingual Glands and Their Function
Located on either side beneath the tongue are paired sublingual salivary glands. These are among three major types of salivary glands (others being parotid and submandibular). Sublingual glands produce mainly mucous-type saliva that lubricates food during chewing and swallowing.
They release saliva through numerous small openings called Rivinus ducts scattered across the floor of the mouth. This continuous secretion keeps oral tissues moist, aids taste perception by dissolving food particles, and helps prevent tooth decay by neutralizing acids produced by bacteria.
Blood Vessels and Nerves
The floor of the mouth contains several important blood vessels such as branches of the lingual artery and vein. These vessels supply oxygenated blood to tongue muscles and surrounding tissues while draining deoxygenated blood away.
Nerve supply includes branches from cranial nerves responsible for taste sensation (chorda tympani nerve) and general sensation (lingual nerve). Damage or trauma to these nerves can result in numbness or altered taste perception on one side of the tongue.
Common Conditions Affecting The Area Under The Tongue
Several medical conditions specifically involve or affect this sensitive area:
Ankyloglossia (Tongue-Tie)
As mentioned earlier, ankyloglossia occurs when a tight or short lingual frenulum restricts tongue movement. This can cause feeding problems in infants or speech impediments later on.
Symptoms include difficulty lifting or protruding the tongue beyond teeth, trouble licking lips or playing wind instruments. Treatment typically involves a simple surgical procedure to release tension on this tissue.
Sublingual Cysts (Ranulas)
Ranulas are mucus-filled cysts that develop when ducts from sublingual glands become blocked. They appear as bluish swellings beneath the tongue’s surface. Large ranulas may interfere with speech or swallowing if left untreated.
Surgical drainage or marsupialization is often necessary for persistent cases to prevent recurrence.
Oral Cancer
Though less common than other sites in the mouth, cancers can develop under the tongue affecting tissues including mucosa and salivary gland ducts. Early signs include persistent ulcers, lumps, pain, or difficulty moving the tongue.
Regular dental check-ups help detect suspicious lesions early for timely intervention.
Sialolithiasis (Salivary Stones)
Salivary stones sometimes form within ducts draining sublingual glands leading to painful swelling during meals due to blocked saliva flow. Symptoms include dry mouth sensation and discomfort under the tongue.
Treatment ranges from massage techniques encouraging stone expulsion to minor surgery in severe cases.
The Role Of The Floor Of The Mouth In Oral Drug Absorption
One fascinating aspect tied closely with this area is its role in drug administration via sublingual absorption. Medications placed under the tongue dissolve rapidly due to rich vascularization allowing drugs direct access into systemic circulation bypassing digestive degradation.
Common drugs administered sublingually include nitroglycerin for angina relief or certain sedatives requiring fast onset action. This route offers quick absorption compared to oral ingestion where drugs undergo first-pass metabolism in liver reducing bioavailability.
The thin mucous membrane combined with abundant capillaries makes it an ideal site for efficient drug delivery without injections.
The Anatomy In Numbers: A Quick Reference Table
| Structure | Description | Function |
|---|---|---|
| Lingual Frenulum | Mucous membrane fold connecting underside of tongue to floor | Stabilizes tongue; allows movement for speech & eating |
| Sublingual Glands | Paired salivary glands beneath tongue; multiple small ducts (Rivinus) | Secretes saliva for lubrication & oral hygiene |
| Lingual Artery & Vein | Main blood vessels supplying/draining floor & tongue muscles | Nourishes tissues; removes deoxygenated blood |
Caring For The Area Under The Tongue- What Is It Called?
Maintaining good oral hygiene ensures this delicate region stays healthy:
- Regular Brushing: Use a soft-bristled toothbrush gently cleaning all surfaces including underneath your tongue.
- Mouthwash Use: Antimicrobial rinses help reduce bacterial buildup around sublingual areas.
- Avoid Trauma: Avoid biting down hard on objects that could injure your frenulum or floor tissue.
- Dental Visits: Routine check-ups allow professionals to inspect hidden areas under your tongue for abnormalities.
- Adequate Hydration: Keeps saliva flowing optimally preventing dry mouth issues.
If you notice pain, swelling, difficulty moving your tongue freely, or persistent sores underneath your tongue—seek professional evaluation promptly as these could signal underlying health issues needing treatment.
Tongue Mobility And Its Impact On Daily Life
The freedom with which you move your tongue depends heavily on structures beneath it. Restricted movement caused by issues with this area can lead to:
- Difficulties pronouncing certain sounds clearly.
- Trouble manipulating food inside your mouth leading to inefficient chewing.
- Poor oral clearance increasing risk for cavities and infections.
- Lactation problems in newborns if ankyloglossia affects breastfeeding mechanics.
Fortunately, many mobility restrictions are treatable with minor interventions restoring full function quickly without lasting effects on quality of life.
