How well do you know your basic anatomy?

Health screening campaigns which target a specific organ may lack effectiveness if the public have a poor knowledge of anatomy, say researchers.

Middle-aged non-graduates scored better than young graduates in an anatomical quiz given to the public by researchers from Lancaster Medical School in the UK. The research has been published in the journal Anatomical Sciences Education.

Dr Adam Taylor said: “Whilst many of the public do not have or need formal anatomical knowledge, it is beneficial in monitoring and explaining their own health.”

Given a blank diagram (template) of the human body, people of various ages, jobs, and educational backgrounds were asked where the following structures were located:

brain
cornea
lungs
liver
diaphragm
heart
stomach
appendix
bladder
kidneys
pancreas
gallbladder
spleen
adrenals
thyroid
hamstrings
biceps
triceps
quadriceps
cruciate ligament
Achilles tendon

These terms were chosen based on mentions in everyday life such as keeping fit, sports injuries, TV shows, and online searches for abdominal pain.

The only organ which 100 percent of people answered correctly was the brain. The biceps muscle and the cornea were the next most correctly answered structures.

The organs which the public knew least about were the adrenal glands, which less than 15 percent of people could identify and many thought mistakenly were in the neck.

  • Men scored higher than women in identifying muscles but not internal organs.
  • Graduates did not score better than non-graduates
  • Older people scored higher than young people, peaking in the 40–49 age group which may be because this is when people begin visiting the doctor more often
  • People working in any health-related job scored significantly higher than people in other jobs.
  • People who had visited a healthcare professional prior to the quiz fared no better than those who had not.

Dr Taylor said the quiz revealed the public’s eagerness to learn anatomy despite their limited knowledge of the human body.
