connective-tissue cells which is separated from the ventral 

 surface of the brain by a layer of fibrous connective tissue. 

 Throughout this region the trabeculae cranii are circular in 

 cross-section.

As the divergence of the trabeculae becomes greater, the 

 parasphenoid lamella remains as a small spicule in the median 

 part of the fenestra and is widely separated from the trabeculae 

 cranii. The gasserian ganglion lies in a space between each
