Anatomy of the Newborn Skull. Click Image to Enlarge. Although the skull appears to be 1 large bone, there are actually several major bones that are connected together. The major bones that compose the skull of a newborn include the following: 2 frontal bones. 2 parietal bones.
The first stage begins in the unborn baby at about 6 weeks of pregnancy (gestation). This is when the basic substance of the tooth forms. Next, the hard tissue that surrounds the teeth is formed around 3 to 4 months of gestation.
A baby’s skull serves as durable armor that protects one of the most sensitive organs in the known universe—the human brain—and yet must remain flexible enough to expand quickly in three dimensions, doubling in volume in a few short months.
The CT scan showed that the cranial sutures in Nazir’s skull had closed too early, typical of a rare and sometimes serious condition called craniosynostosis. The doctor suspected that it might be causing delays in Nazir’s growth.
At the base of the skull is bone that supports 4 brain components—the frontal lobe, temporal lobe, brain stem, and cerebellum. The skull base offers support from the bottom of the brain. Think of it as the floor of the skull, where the brain sits.
Craniosynostosis is a condition where one or more of the sutures close too early. This may cause: Problems with normal brain and skull growth. More pressure than normal inside the head. Skull or facial bones to become irregular in shape. The problem occurs in 1 in every 2,000 live births.
A head injury is a broad term that describes many injuries that occur to the scalp, skull, brain, and underlying tissue and blood vessels in the head. Head injuries are also commonly referred to as brain injury, or traumatic brain injury (TBI), depending on the extent of the head trauma.
Flat head syndrome (deformational plagiocephaly) is when a baby’s head develops a lasting flat spot. The flat spot may be either on one side of the head or on the back of the head. This happens when a baby sleeps in the same position most of the time or because of problems with the neck muscles.
Craniofacial anomalies (CFA) are a diverse group of deformities in the growth of the head and facial bones. Anomaly is a medical term meaning "irregularity" or "different from normal." These abnormalities are present at birth (congenital) and there are numerous variations.
Both kinds of hydrocephalus lead to a buildup of pressure inside the skull. In babies, whose cranial bones are not yet fully fused to one another, this pressure can force those bones apart, causing the head to grow abnormally large.
