Intracranial pressure
Intracranial Pressure
Intracranial pressure (ICP) is the pressure inside the skull and thus in the brain tissue and cerebrospinal fluid (CSF). The body has various mechanisms by which it keeps the ICP stable, with CSF pressures varying by about 1 mmHg in normal adults through shifts in production and absorption of CSF.
Pronunciation
Intracranial pressure is pronounced as /ˌɪntrəkrəˈneɪl ˈprɛʃər/.
Etymology
The term "intracranial pressure" is derived from the Latin words "intra" meaning "within", "cranium" meaning "skull", and the English word "pressure".
