Learning Objectives

• List the structures that comprise the respiratory system
• Describe the larynx and its function in respiration and phonation
• Describe the conducting system of the respiratory tract
• Describe lung morphology
• Review the location of the lungs and pleura in the thoracic cavity
• Describe the neurovascular supply of the lungs
• Describe the larynx and its function in respiration and phonation
• Describe the functional development of the respiratory system
• Discuss the stages of lung development and the characteristics of each stage
• Describe the hyoid bone and the cartilages of the larynx. Explain how these are linked together by laryngeal membranes
• Describe the intrinsic and extrinsic laryngeal muscles responsible for closing the laryngeal inlet and controlling vocal cord position and tension. Explain how these muscles function during phonation, laryngeal closure, cough/sneeze reflexes, and regulation of intra-thoracic and Intra-abdominal pressures
• Describe the origin, course, and functions of the motor and sensory nerve supply of the larynx and the functional consequences of injury to these nerves
• Resources

• how does the structure of the conchae relate to its function?
• why is this important in both inspiration and expiration?
• what are the paranasal sinuses?
