Study Notes
Pressure Inside the Skull
- The brain contains approximately 150 cm³ of cerebrospinal fluid (CSF) in a series of interconnected openings called ventricles.
- If the opening is blocked at birth, the CSF becomes trapped inside the skull, increasing the internal pressure, leading to a serious condition called hydrocephalus.
Hydrocephalus Measurement
- Crude Method:
- Measures the circumference of the skull just above the ears.
- Normal values for newborn infants are between 32-37 cm.
- Values larger than this may indicate hydrocephalus.
- Qualitative Method (Transillumination):
- Uses light-scattering properties to measure hydrocephalus.

Description
Test your knowledge on hydrocephalus, a condition where cerebrospinal fluid accumulates inside the skull leading to increased intracranial pressure. Learn about the measurement methods used to assess this condition.
