It is important to leave it intact to prevent infections or injury to the underlying brain tissue. If you have concerns about the fontanel, it is best to consult a healthcare professional for guidance.
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 fontanel between the parietal and occipital bone?
The fontanel located between the parietal and occipital bones is known as the posterior fontanel. It is a soft spot on an infant's skull that typically closes within the first few months after birth. This fontanel allows for flexibility during childbirth and accommodates the rapid growth of the brain during early development.
Is the coronal fontanel medial to the posterior fontanel?
The posterior fontanel would be in the back of the head. The coronal fontanel would be located in another part of the brain.
What are the names of the fontanels in fetal skull?

What bone articulates with the inferior border of the zygomatic bone?
The maxilla bone articulates with the inferior border of the zygomatic bone. This articulation forms part of the mid-face structure and helps support the cheekbones and surrounding facial features.
What are all the bones that fuse together besides the fontanel?
The fontanel fuses through a process of intramembranous ossification. Most of the other bones in the body undergo intracartilaginous ossification. There are many bones that do this, in particular, one of them is the coxal bone, also called the OS coxa, and it starts out as three separate bones; ilium, ischium, and pubis.
