Study Notes
Oral Cavity Components
- Upper Lip: The soft tissue structure above the mouth, playing a role in speech and facial expression.
- Superior Labial Frenulum: A fold of mucous membrane that connects the upper lip to the gums.
- Gingivae (gums): Tissues surrounding the teeth, providing support and protection.
- Palatine Raphe: A midline ridge on the hard palate formed by the fusion of the palatine processes.
- Hard Palate: The bony front part of the roof of the mouth, crucial for speech and swallowing.
- Soft Palate: The flexible back part of the roof of the mouth, aiding in the distinction between oral and nasal cavities.
- Uvula: A small, fleshy extension at the back of the soft palate, involved in speech and swallowing.
- Palatine Tonsil: Lymphoid tissue located on either side of the oropharynx, involved in immune response.
- Sublingual Folds with Openings of Sublingual Ducts: Folds under the tongue containing openings for salivary glands, aiding in digestion.
- Lower Lip: The soft tissue structure below the mouth, important for oral functions.
- Oral Vestibule: The space between the lips/cheeks and the teeth, playing a role in oral hygiene.
- Inferior Labial Frenulum: A fold of tissue connecting the lower lip to the gums.
- Opening of Submandibular Duct: The entry point for submandibular salivary glands beneath the tongue, facilitating saliva flow.
- Lingual Frenulum: A fold of tissue that anchors the tongue to the floor of the mouth, limiting its movement.
- Tongue: A muscular organ involved in taste, manipulation of food, and speech.
- Posterior Wall of Oropharynx: The back wall of the throat area shared by the oral and nasal cavities.
- Palatopharyngeal Arch: A fold of tissue extending from the soft palate down to the pharynx.
- Palatoglossal Arch: A fold of tissue that runs from the soft palate to the tongue, containing muscles aiding in swallowing.
Pharyngeal Structures
- Trachea: The airway leading to the lungs, following the larynx, essential for respiration.
- Esophagus: A muscular tube connecting the throat (pharynx) with the stomach, crucial for transporting food.
- Laryngopharynx: The part of the pharynx that is located behind the larynx, leading to both the esophagus and trachea.
- Hyoid Bone: A U-shaped bone in the neck that supports the tongue and plays a role in swallowing.
- Epiglottis: A flap of cartilage that covers the windpipe during swallowing to prevent food from entering the airway.
- Lingual Tonsil: Lymphoid tissue located at the base of the tongue, involved in immune function.
- Oropharynx: The middle section of the pharynx located behind the oral cavity, important for both air and food passage.
