Sutures And Fontanels

The Coronal Suture is the suture that separates the frontal bone from the two parietal bones in the human skull. The other sutures mentioned in the incorrect answers have different locations and functions within the skull.

The sagittal suture is the suture that runs along the top of the skull from front to back, separating the parietal bones. The other sutures mentioned are also important cranial sutures but do not fit the description provided in the question.

The Lambdoid Suture is located at the back of the skull, while the Sagittal Suture runs from front to back, the Coronal Suture runs from side to side, and the Squamous Suture is on the side of the skull.

The squamous suture(s) are located on each side of the skull, not at the top (lambdoid), front (coronal), or center (sagittal) of the skull.

The soft spot at the back of a baby's head is known as the Posterior Fontanel. It closes up within a few months after birth as the skull bones fuse together. The Anterior Fontanel is located at the top/front of the head, while there is no such thing as the Lateral or Midline Fontanel.

The correct answer is Anterolateral Fontanel, as it is the fontanel located on the anterolateral side of the skull. The Occipital Fontanel is located at the back of the skull, the Sphenoid Fontanel is located on the side of the skull near the sphenoid bone, and the Temporal Fontanel is located on the side of the skull near the temporal bone.

The soft spot on a baby's skull is formally known as the Anterior Fontanel, which typically closes by around 18 months of age. It allows for the baby's head to pass through the birth canal during childbirth and provides flexibility for their rapidly growing brain.
