Pre-auricular Sulcus helps in the determination of

  • A.Age
  • B.Sex
  • C.Stature
  • D.Race

Answer: B

The pre-auricular sulcus helps in determining sex. It is a groove on the ilium of the pelvis, below the auricular surface, which is prominent in females, where it is related to pregnancy and child birth, and usually absent or shallow in males. Age is estimated from the pubic symphysis, epiphyseal fusion and teeth, stature from the long bones, and race from the skull, so these three are not what the groove is used for. Option B is correct.
