Which characteristic anatomical feature is commonly associated with Down syndrome?

• A. A prominent forehead
• B. A round head with a flat occiput
• C. Long limbs
• D. A narrow face

Answer: (B)

The characteristic anatomical feature commonly associated with Down syndrome is a round head with a flat occiput. This feature is a result of the atypical development that occurs with the genetic condition, which is caused by the presence of an extra copy of chromosome 21. Individuals with Down syndrome often exhibit distinct physical traits, one of which includes brachycephaly, or a broader and rounder head shape. The flatness at the back of the head, known as the flat occiput, is particularly notable and contributes to the characteristic appearance of individuals with this condition. This distinctive head shape, alongside other features like a short neck and low-set ears, helps clinicians and healthcare professionals recognize Down syndrome in patients. Understanding these physical characteristics is important in offering appropriate care and support to individuals with Down syndrome and their families.
