Study Notes
Nasal Structures
- Superior Nasal Conchae: Scroll-like structures in the nasal cavity that help filter and humidify air.
- Middle Nasal Conchae: Located between the superior and inferior nasal conchae, aiding in airflow regulation.
- Inferior Nasal Conchae: The largest of the conchae, contributing significantly to air filtration.
Pharynx Regions
- Nasopharynx: The upper part of the pharynx behind the nose, serving as an air passage.
- Oropharynx: The middle part of the pharynx located behind the mouth, involved in both air and food passage.
- Laryngopharynx: The lower part of the pharynx that connects to both the esophagus and larynx.
Laryngeal Structures
- Epiglottis: A flap of tissue that covers the windpipe during swallowing to prevent food from entering the airway.
- Larynx: Also known as the voice box, it houses the vocal cords and is involved in sound production.
Respiratory Tract Components
- Trachea: The windpipe, a crucial passage for air to reach the bronchi and lungs.
- Primary Bronchi: The initial branches of the trachea that lead into each lung.
- Bronchioles: Smaller branches of the bronchi that lead to the alveoli, where gas exchange occurs.
- Pulmonary Arteries: Blood vessels transporting deoxygenated blood from the heart to the lungs for oxygenation.
Lung Anatomy
- Lungs: Paired organs that facilitate gas exchange; consist of lobes and are organized into specific regions.
- Left Superior Lobe: The upper section of the left lung, assisting in oxygen intake.
- Right Superior Lobe: The upper section of the right lung, similarly responsible for gas exchange.
- Left Inferior Lobe: The lower section of the left lung, contributing to overall lung capacity.
- Right Inferior Lobe: The lower section of the right lung, completing the lung's functional capacity.
- Right Middle Lobe: Located between the superior and inferior lobes of the right lung.
Fissures and Notches
- Horizontal Fissure: Separates the right upper lobe from the middle lobe of the right lung.
- Oblique Fissure: Divides both the left and right lungs into upper and lower lobes; more pronounced on the left lung.
- Cardiac Notch: A concave space in the left lung accommodating the heart's position.
Cartilages in the Larynx
- Arytenoid Cartilage: Paired structures that play a key role in the movement of vocal cords during sound production.
- Cricoid Cartilage: A ring-shaped cartilage that provides structural support to the larynx.
- Thyroid Cartilage: The largest laryngeal cartilage, forming the Adam’s apple, and protecting the vocal cords.
Additional Structures
- Vocal Fold: Folds of tissue in the larynx that vibrate to produce sound.
- Sphenoidal Sinus: Air-filled spaces in the sphenoid bone, contributing to skull lightness and resonance.
- Frontal Sinus: Located in the forehead region, also involved in the resonance of voice and lightening skull weight.
- Hilum: The medial groove in the lungs that allows entry for bronchi and blood vessels.
