Light micrographs representing a transverse section of the bottlenose dolphin. (Tursiops truncatus) superior sagittal sinus displaying the histomorphology of the parasagittal structures stained with Hematoxylin and Eosin. Scale bars represent 100Ā Ī¼m. (A) Composite photomicrograph of histological section displaying the superior sagittal sinus (SSS) in transverse section (KLC 360). Boxes correspond to sites of (B), (C), and (D) in this figure. Box (E) corresponds to the site of Fig.Ā 8A. The SSS is located between the periosteal (PDL) and meningeal (MDL) dural layers, which laterally fuse around the SSS and extend ventrally to form the falx cerebri (FC) separating the cerebral hemispheres (CH). The subarachnoid space (SAS) lies between the dural SSS and CH. Arachnoid granulations (arrows) are shown perforating the dura mater. (B) Dural blood vessel (BV), in this case a dorsal cerebral vein, is shown in close juxtaposition to the lateral margin of the SSS. (C) Arachnoid granulation (AG) demonstrating the connective tissue core (CTC), meningothelial cell lining (MCL), and subcapsular space (SCS) are shown surrounded by a capsule (CAP) of arachnoid cells. (D) Located between the PDL and MDL are meningeal lymphatic vessels (arrowheads) closely clustered near a venule (V) and arteriole (A).
