Study Notes
Nasal Cavity and Related Structures
- Frontal Sinus: Air-filled cavities located within the bones of the forehead, contributing to resonance and reducing skull weight.
- Superior Nasal Conchae: Bony structures in the nasal cavity, involved in air filtration, temperature regulation, and moisture retention.
- Middle Nasal Conchae: Positioned below the superior conchae, assists in humidifying and cleaning inhaled air.
- Inferior Conchae: The largest conchae, these bone structures enhance air turbulence, aiding in effective filtration and warming.
- Nasal Vestibule: The front area of the nasal cavity, lined with skin and containing hairs that trap dust and debris.
- External Nares: The nostrils, serving as the entry point for air into the nasal cavity.
- Hard Palate: The bony roof of the mouth, separating the oral cavity from the nasal cavity for proper air and food passage.
- Oral Cavity: The mouth area, involved in digestion and speech, containing teeth, tongue, and salivary glands.
- Tongue: A muscular organ that aids in food manipulation, swallowing, and speech; it has taste buds for flavor perception.
- Mandible: The jawbone, the only movable bone of the skull, crucial for chewing and speaking.
- Lingual Tonsil: Located at the base of the tongue, these lymphoid tissues help in immune response.
- Hyoid Bone: A U-shaped bone in the neck, supporting the tongue and providing attachment for muscles.
- Thyroid Cartilage: The largest cartilage in the larynx, providing structure and protection for the vocal cords.
- Cricoid Cartilage: A ring-shaped cartilage below the thyroid that supports the airway and anchors vocal cords.
- Trachea: The windpipe, transporting air to and from the lungs; lined with cilia to trap particulates.
- Thyroid Gland: An endocrine gland located in the neck, regulating metabolism, growth, and development through hormone secretion.
- Esophagus: A muscular tube connecting the throat to the stomach, facilitating the passage of food.
- Vocal Fold: Folds of tissue that vibrate to produce sound; essential for phonation and voice modulation.
- Glottis: The opening between the vocal folds, playing a crucial role in sound production and airflow regulation.
- Laryngopharynx: The lower part of the pharynx located behind the larynx, serving both respiratory and digestive functions.
- Aryepiglottic Fold: A fold of tissue from the side of the epiglottis to the arytenoid cartilage, aiding in protecting the airway.
- Epiglottis: A flap of cartilage that covers the windpipe while swallowing, preventing food from entering the airway.
- Oropharynx: The middle portion of the pharynx, connecting the oral cavity to the pharynx; involved in swallowing and respiration.
- Palatine Tonsil: Lymphoid tissues located on either side of the oropharynx, part of the immune system.
- Soft Palate: The flexible back portion of the roof of the mouth, essential for swallowing and speaking.
- Entrance to Auditory Tube: The opening that connects the middle ear to the nasopharynx, important for equalizing ear pressure.
- Pharyngeal Tonsil: Also known as adenoids, located in the nasopharynx, important for immune response.
- Nasopharynx: The upper part of the pharynx, behind the nasal cavity, involved in the respiratory system.
- Internal Nares: Internal openings of the nasal cavity leading to the nasopharynx.
- Nasal Cavity: The hollow space behind the nose, responsible for filtering, warming, and humidifying inhaled air.
