This section offers **concise, exam-focused notes** on the **oral cavity** and **salivary glands**, curated to help **MBBS and ENT students** prepare confidently for theory exams, practicals, and clinical discussions. ### What are the Oral Cavity and Salivary Glands? The **oral cavity** marks the beginning of the **digestive** and **respiratory** tracts. It plays essential roles in **mastication**, **speech**, **taste**, and **deglutition**. It includes structures like the **tongue**, **teeth**, **palate**, **floor of mouth**, and **buccal mucosa**. The **salivary glands** - **parotid**, **submandibular**, and **sublingual** - produce saliva, which aids in digestion, lubrication, and oral health. These glands are clinically important in cases of **sialadenitis**, **sialolithiasis**, **tumors**, and **nerve injuries** during surgeries. --- Here you’ll find high-yield notes covering: - Anatomy of the oral cavity and salivary glands - Blood supply, lymphatic drainage, and innervation - Muscles of the tongue and floor of the mouth - Physiology of salivation - Pathologies: ulcers, leukoplakia, malignancies, infections - Sialadenitis and sialolithiasis - diagnosis and treatment - Tumors of the parotid and submandibular glands - Surgical approaches and complications (e.g., facial nerve preservation) - Viva and MCQ-friendly facts All notes are designed for **quick revision**, **conceptual clarity**, and **clinical application**. ## Notes in this Category - [Adenoid Cystic Carcinoma](https://www.theentresident.com/ent-notes-lectures/adenoid-cystic-carcinoma-histology-treatment.md): ENT notes on Adenoid Cystic Carcinoma - Histogenesis, Histology, Symptoms, Investigations, Treatment and Recurrence. - [Anatomy of Parotid Gland](https://www.theentresident.com/ent-notes-lectures/parotid-gland-anatomy.md): ENT notes on the parts, relations, lobes, nerve supply, blood supply, and lymphatic drainage of the parotid gland. - [Anatomy of Submandibular and Sublingual Glands](https://www.theentresident.com/ent-notes-lectures/submandibular-sublingual-gland-anatomy.md): ENT notes on the parts, relations, lobes, nerve supply, blood supply, and lymphatic drainage of the Submandibular and Sublingual Glands. - [Anatomy of the Tongue](https://www.theentresident.com/ent-notes-lectures/tongue-anatomy.md): ENT notes on the parts, structure, muscles, nerve supply, blood supply, and lymphatic drainage of the tongue. - [Benign Salivary Gland Tumors](https://www.theentresident.com/ent-notes-lectures/benign-salivary-gland-tumors.md): ENT notes on Benign Salivary Gland Tumors - Causes, WHO Classification, Symptoms, Investigations and Treatment. - [Development of the Tongue](https://www.theentresident.com/ent-notes-lectures/development-of-tongue.md): Understand the embryological development of the tongue. - [Developmental Anomalies of the Tongue](https://www.theentresident.com/ent-notes-lectures/developmental-anomalies-of-tongue.md): Understand the congenital anomalies of the tongue, their embryological basis, and clinical relevance. - [Lymphatic Drainage of Tongue](https://www.theentresident.com/ent-notes-lectures/lymphatic-drainage-tongue.md): A detailed, clinically important overview of the lymphatic drainage of the tongue. - [Malignant Salivary Gland Tumors](https://www.theentresident.com/ent-notes-lectures/malignant-salivary-gland-tumors.md): ENT notes on Malignant Salivary Gland Tumors - Causes, WHO Classification, Symptoms, Investigations and Treatment. - [Mucoepidermoid Carcinoma](https://www.theentresident.com/ent-notes-lectures/mucoepidermoid-carcinoma-histology-treatment.md): ENT notes on Mucoepidermoid Carcinoma - Histogenesis, Histology, Symptoms, Investigations, Treatment and Recurrence. - [Muscles of Tongue](https://www.theentresident.com/ent-notes-lectures/muscles-of-tongue.md): A detailed overview of the muscles of the tongue. - [Nerve Supply of Tongue](https://www.theentresident.com/ent-notes-lectures/nerve-supply-tongue.md): A detailed explanation of the motor and sensory nerve supply of the tongue. - [Pleomorphic Adenoma](https://www.theentresident.com/ent-notes-lectures/pleomorphic-adenoma-histology-treatment.md): ENT notes on Pleomorphic Adenoma - Histogenesis, Histology, Symptoms, Investigations, Treatment and Recurrence. - [Relations of Hyoglossus Muscle](https://www.theentresident.com/ent-notes-lectures/hyoglossus-muscle-relations.md): Understand the superficial and deep relations of the hyoglossus muscle useful for anatomy theory and viva. - [Warthin Tumor](https://www.theentresident.com/ent-notes-lectures/warthin-tumor-histology-treatment.md): ENT notes on Warthin Tumor - Histogenesis, Histology, Symptoms, Investigations, Treatment and Recurrence. --- ## About This Category Oral Cavity and Salivary Glands is one of the free ENT note categories published by The ENT Resident.
