Anatomy and Cell Biology 3319 Lecture Notes - Lecture 13: Temporal Lobe, Straight Sinus, Spinal Canal
Document Summary
Explain the anatomical arrangement of the dural folds and the corresponding dural venous sinuses. Correctly describe the anatomy, function, and relationships of the meningeal layers. Describe the anatomical organization of the ventricles and their interconnections. Discuss the importance of csf and illustrate its pathway of flow through the ventricular system. Analyze how some anatomical structures may be implicated with various clinical cases. Meninges: connective tissue coverings of the brain and spinal cord: dura mater, arachnoid mater, and pia mater. Middle meningeal layer that spans over the surface of the gyri. Thin, avascular (i. e. no vasculature in here) fibrous membrane: however, there is vasculature in subarachnoid space (e. g. cerebral arteries, veins) and is filled with csf. Filaments anchored to pia mater giving spider web appearance. Contains filaments (green) within the subarachnoid space, anchoring the arachnoid mater to the pia mater. Firmly adhered to the surface of the brain, spinal cord, and origins of cranial nerves, such that it cannot be separated.
