What examiners said
Comprehensive responses • The structures most often labelled correctly were the diaphragm and an alveolus. Limited responses • The larynx was often identified as the trachea. • Some candidates named fewer than four structures indicating that they would benefit from greater familiarity with the diagram. • Most candidates would benefit from knowledge of the position of the intercostal muscles, as t...
