Study Notes
Upper Respiratory Tract Structures
-
Esophagus: Tube connecting the throat (pharynx) to the stomach, important for food passage.
-
Trachea: Windpipe that provides a passage for air to reach the lungs, composed of rings of cartilage.
-
Laryngopharynx: Lower part of the pharynx, situated behind the larynx, it serves as a pathway for both air and food.
-
Palatine Tonsils: Lymphoid tissues located on both sides of the throat, play a role in immune response.
-
Uvula: Small, hanging structure at the back of the throat, aids in speech and prevents food from entering the nasal cavity.
-
Nasopharynx: Upper part of the pharynx located behind the nasal cavity, connects nasal passages with the throat and houses adenoid tissues.
-
Pharyngeal Tonsil: Lymphatic tissue located in the nasopharynx, part of the immune system, helps capture pathogens.
-
Sphenoid Sinus: Air-filled spaces within the sphenoid bone, located behind the nasal cavity, contribute to voice resonance and reduce skull weight.
-
Frontal Sinus: Pair of air-filled spaces located above the eyes in the frontal bone, involved in mucus production and drainage.
-
Superior, Medial, and Inferior Nasal Conchae: Bony structures in the nasal cavity, responsible for increasing surface area, humidifying, and filtering inspired air.
-
Vestibule: The anterior portion of the nasal cavity, acts as the first entrance for air and contains hair and skin for filtration.
-
Nostrils: External openings of the nose, allowing air to enter and exit the respiratory system.
-
Hard Palate: Bony structure forming the roof of the mouth, separates the nasal cavity from the oral cavity.
-
Soft Palate: Muscular and flexible portion at the back of the roof of the mouth, important for swallowing and speech.
-
Tongue: Muscular organ in the mouth, crucial for taste, swallowing, and speech production.
-
Lingual Tonsils: Lymphoid tissue located at the base of the tongue, part of the immune system.
-
Hyoid Bone: U-shaped bone in the neck that supports the tongue and aids in swallowing.
-
Epiglottis: Flap of cartilage at the root of the tongue, prevents food from entering the windpipe during swallowing.
-
Vestibular Fold: Also known as false vocal cords, located above the true vocal cords, involved in protecting the airway.
-
Thyroid Cartilage: Largest cartilage in the larynx, also known as the Adam's apple, provides protection for the vocal cords.
-
Vocal Fold: True vocal cords located within the larynx, responsible for sound production by vibrating as air passes through.
-
Cricoid Cartilage: Ring-shaped cartilage located below the thyroid cartilage, provides support and maintains the airway structure.
-
Thyroid: A hormone-producing gland located in the neck, plays a vital role in metabolism and growth.
