5 Questions
What serious condition is caused by the blockage of the opening that allows cerebrospinal fluid to flow out of the skull?
Hydrocephalus
Which method involves measuring the circumference of the skull just above the ears to detect hydrocephalus?
Crude method
What is the normal range of skull circumference for newborn infants according to the text?
32-37 cm
What qualitative method uses light-scattering properties to detect hydrocephalus?
Transillumination
What happens if cerebrospinal fluid is trapped inside the skull due to a blockage at birth?
Increased internal pressure
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.
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.
