Select the main structures that affect intracranial pressure:

The main structures that affect intracranial pressure include the brain, cerebrospinal fluid (CSF), and blood, with each playing a critical role in maintaining the balance of intracranial components. The brain has a higher volume compared to the other components and any increase in its mass, such as in cases of tumors, edema, or hemorrhage, can significantly raise intracranial pressure.

Cerebrospinal fluid serves as a cushioning and protective mechanism for the brain, and alterations in its volume or production can directly impact intracranial pressure. Similarly, changes in the volume of blood within the cranial cavity, such as during vascular incidents like hemorrhagic strokes or venous obstruction, will also influence pressure dynamics.

Neurons themselves do not directly alter intracranial pressure; rather, they are a part of the brain's structure. While neuronal health and integrity are vital for overall brain function, they do not operate independently in the context of intracranial pressure regulation.

In summary, the brain is indeed a critical component affecting intracranial pressure, but it is also essential to recognize that cerebrospinal fluid and blood are equally influential in maintaining the delicate balance of pressures within the cranial vault. Understanding these interrelationships is key
