Practice Question
Which suture is located between the two parietal bones?
Answer Choices:
Correct Answer:
Sagittal suture
Rationale:
💀The sagittal suture is the fibrous joint that joins the two parietal bones along the midline of the skull.
💀It extends anteriorly to posteriorly between the coronal suture (front) and the lambdoid suture (back), forming the top median seam of the cranial vault.
💀This suture allows for slight movement during birth and accommodates brain growth in infancy before eventual fusion in adulthood.
💀Knowledge of cranial sutures is critical in neuroanatomy and obstetrics, especially when assessing fontanelle location and skull shape in infants.
💀Once fused, the sagittal suture becomes a synostosis, helping maintain cranial stability.
