📝 Quick Tips for Writing Long Answer Questions

• Always use the headings given in the question as your answer subheadings
• Draw a labelled diagram for every joint, nerve, and gland question - examiners give 2-3 marks just for diagrams
• End every answer with applied anatomy / clinical correlate - that's where most marks are
• For joints: always follow the sequence - type > articular surfaces > capsule > ligaments > relations > movements > blood supply > applied
• For nerves: origin > course > branches > distribution > applied
• For glands: situation > shape/size > parts > relations > blood supply > nerve supply > lymphatics > applied
