Why does your skull not protect your brain as much as you would think?

Skul along with CSF and meninges provide protection to brains and hence it would be wrong to say that only skull provides protection to brain

Explanation:

It is not the skull only that protects the brain. Actually a set of tissues and fluid along with the skull protects the brains. For instance, the Cerebrospinal fluid (CSF) plays an essential role in preventing brain from any injury by enacting as a cushion between the skull and brain. Meninges are set of three tissues that lie between the brain and skull and provide coverage and protection to the brain.

Hence, skull do not protect our brain as much as we think
