What is pulsating beneath the anterior fontanel?
Beneath the anterior fontanel, which is the soft spot located on an infant's skull, pulsations can be observed due to the underlying blood vessels, particularly the anterior cerebral arteries. These pulsations are often more noticeable when the baby is crying or exerting effort. The anterior fontanel allows for the brain's growth and development during infancy and serves as an indicator of the baby's hydration and intracranial pressure.
What is a boat-shaped abdomen?

What Retraction of big fontanel can be seen in?
Retraction of the big fontanel, also known as the anterior fontanel, can be seen in infants who are dehydrated or experiencing increased intracranial pressure. Dehydration can lead to a sunken appearance of the fontanel, while increased pressure may cause it to bulge. It is important to monitor the fontanel's condition as it can provide insight into the infant's overall health. If concerns arise, medical evaluation is recommended.
What are the names of the fontanels in fetal skull?
Anterior (frontal) Fontanel Posterior (occipital) Fontanel Anterolateral (sphenoid) Fontanel Posterolateral (mastoid) Fontanel
How many fontanels has a fetal skull?

What are the four fontanels of an infant?
The four fontanels of an infant are the anterior fontanel, posterior fontanel, sphenoid fontanel, and mastoid fontanel. The anterior fontanel, located at the top of the head, is the largest and typically closes by 18-24 months. The posterior fontanel, situated at the back of the head, generally closes by 2-3 months. The sphenoid and mastoid fontanels are smaller and close within the first year of life.
Which one of the fontanels is the most dorsal?
