Question

Give the 4 dural folds in the skull and determine their positioning and function

Answer 1

The 4 dural folds in the skull are Tentorium cerebelli, Falx cerebri, Falx cerebelli, and Diaphragma sellae. These folds provide support and separation for different regions of the brain.

Step-by-step explanation:

The 4 dural folds in the skull are:

1. Tentorium cerebelli - This fold separates the cerebrum and the cerebellum. It is located above the cerebellum and below the occipital lobes of the cerebrum.
2. Falx cerebri - This fold goes through the midline separation of the cerebrum. It is located between the two cerebral hemispheres.
3. Falx cerebelli - This fold goes through the midline separation of the cerebellum. It is located between the two cerebellar hemispheres.
4. Diaphragma sellae - This fold surrounds the pituitary gland. It is located in the sella turcica of the sphenoid bone.

The function of these dural folds is to provide support and stabilization to the brain, as well as to separate and protect different regions of the brain.
