📖 1. Nasal and Pharyngeal Anatomy

🔑 Key Concepts & Definitions

• Nasal cavity: The large air-filled space above and behind the nose in the middle of the face, responsible for warming, humidifying, and filtering inhaled air (source content).
• Nasal septum: The cartilage and bone structure that divides the nasal cavity into two nostrils, providing support and symmetry (source content).
• Nasopharynx: The upper part of the pharynx located behind the nasal cavity, serving as a passageway for air and connecting the nasal cavity to the oropharynx (source content).
• Nose: The external protrusion of the face that contains the nostrils, involved in respiration, olfaction, and filtering air (source content).
• Oropharynx: The part of the pharynx located behind the oral cavity, serving as a passageway for air and food, connecting the mouth to the laryngopharynx (source content).
• Palate; hard, soft: The structure forming the roof of the mouth; the hard palate is bony and forms the anterior part, while the soft palate is muscular and forms the posterior part, separating the oral cavity from the nasal cavity (source content).
