    Study Notes

    Respiratory System: Nose and Paranasal Sinuses

    • The nose is pyramidal, composed of bony (posterior-inferior) and cartilaginous (anterior-inferior) parts.
    • The nose's skin is thick and rich in sebaceous glands.
    • Nerve supply to the nasal skin comes from the nasociliary branch of the ophthalmic nerve.
    • Blood supply to the external nose comes from facial, infraorbital, and ophthalmic vessels.
    • The nasal cavity has a roof formed of three parts, an anterior sloping portion, a middle horizontal portion (cribriform plate of the ethmoid bone), and a posterior sloping portion (body of the sphenoid bone).
    • The floor of the nasal cavity is formed by parts of the hard palate.
    • The medial wall, or nasal septum, is made of cartilage in front and bone behind.
    • The lateral wall has openings to paranasal sinuses and is composed of multiple bones.
    • The lateral wall is further divided into the vestibule, atrium, and middle meatus and contains nasal conchae (superior, middle, and inferior).
    • Nasal conchae increase the surface area of the nasal cavity, aiding in humidifying and warming inspired air.

    Respiratory System: Paranasal Sinuses

    • Paranasal sinuses are air-filled spaces in the skull bones surrounding the nose.
    • They open into the lateral wall of the nasal cavity.
    • Functions include decreasing skull weight, increasing voice resonance, and warming/moistening the inspired air.
    • Paranasal sinuses include frontal, maxillary, anterior and middle ethmoidal, posterior ethmoidal, and sphenoid sinuses.

    Respiratory System: Larynx

    • The larynx is a tube that extends from the root of the tongue to the cricoid cartilage's lower border.
    • It's composed of nine cartilages (3 single, 3 paired).
    • Single cartilages include the thyroid, cricoid, and epiglottis.
    • Paired cartilages include the arytenoid, corniculate, and cuneiform cartilages.
    • Ligaments and membranes connect these cartilages.
    • The larynx's cavity is divided into the vestibule, sinus, and infraglottic portions.
    • Laryngeal muscles control vocal cord movement (adduction, abduction, stretching, and relaxing), essential for speech production.
    • Nerve supply comes from the recurrent laryngeal nerve and superior laryngeal nerve.
    • Blood supply comes from superior and inferior laryngeal arteries.

    Respiratory System: Trachea and Bronchi

    • The trachea (windpipe) continues from the larynx into the thorax.
    • It divides into the left and right primary bronchi.
    • Its position is in the superior mediastinum.
