THE SUBDURAL SINUS OF THE FRESHWATER CROCODILE (Crocodylus siamensis)

Abstract

A blood sinus suitable for the collection of blood was studied in four freshwater crocodiles (Crocodylus siamensis). The sinus was located in the neck between the dura mater and the archnoid, which gave it its name "the subdural sinus". The procedure of blood collection in crocodiles is discussed in terms of possible injury to the spinal cord and the chance of getting cerebrospinal fluid mixed into the blood sample.
