What is the muscle labelled X in the diagram?
A. Abdominus rectus
B. External obliques
C. Erector spinae
D. Iliopsoas
Markscheme
A
Examiners report
Mid-difficulty question. Answer C provided the greatest distraction. It appears candidates struggled with anterior view and the muscle in isolation. It is a surprise that iliopsoas was an equal distraction to external obliques. However, a legitimate question and responses.
