  9. Anatomy of larynx Larynx is a midline structure, extending from root of tongue to trachea, it lies in front of c3 to c6. in children & females it lies at higher level. PARTS OF LARYNX- larynx consists of skeletal framework of cartilages connected by joints , ligaments& membranes , cartilages are moved by no. of muscles . The cavity is lined by mucus membrane Cartilages: 1, unpaired- epiglottis thyroid cricoid 2, paired- arytenoid cuneiform(c. of wrisberg) corniculate(c. of santorini) www.nayyarENT.com

  10. Ligaments& membranes: Thyrohyoid membrane(extrinsic) Thyrohyoid ligament Cricothyroid membrane(extrinsic) Cricovocal membrane(internal) Cricotracheal membrane(extrinsic) Quadrangular membrane(internal) Anterior commissure tendon(broyle’s ligament) Hyoepiglottic ligament Cricothyroid ligament Joints: Cricothyroid cricoarytenoid www.nayyarENT.com

  11. The Laryngeal Musculature • All The intrinsic muscles of the larynx are paired except transverseinterarytenoid. , all of which are innervated by the recurrent laryngeal nerve, except crico thyroid, • Muscles which change size and shape of inlet of larynx: aryepiglottic& oblique arytenoid • Muscles which move vocal cord: abductors: posterior cricoarytenoid- only abductor www.nayyarENT.com

  12. Adductors: www.nayyarENT.com

  13. Thyroarytenoid - - very broad muscle, usually divided into three parts: • Thyroarytenoideusinternus (vocalis) - adductor and major tensor of free edge of vocal fold. • Thyroarytenoideusexternus- major adductor of vocal fold • Thyroepiglotticus - shortens vocal ligaments www.nayyarENT.com
