Accepted Answer

The spinal fluid is produced continuously through life at about a tablespoonful per hour by structures in the brain. It circulates through it's normal pathway & is absorbed into the circulation from the brain surface. Blockage of flow must be opened or structures distort but the body adjusts to fluctuations in fluid amount.True excess production will produce rapid head growth & need surgery.

Question 8

How to identify the anterior and posterior fontanels of a newborn, explain their functions.?

Accepted Answer

The fontanels can be identified by an exam of the baby's head. They are soft spots that you can feel between the different bones of the skull which have not yet fused. The anterior fontanel is easiest to find be cause it is typically larger. Fontanels do not a have a true function but are fibrous sheets of tissue that connect the plates of the immature skull while protecting the brain below.

If you are checking the fontanelle while your baby is laying down, then it may appear bulging due to gravity, so sit the baby up and check it.  If it is still bulging or if the baby has a fever or is lethargic or inconsolable and very cranky then get your baby checked immediately.
