Which protective covering of the brain provides passageways for cerebrospinal fluid (csf) to drain into the superior sagittal sinus?

The protective covering of the brain that provides passageways for cerebrospinal fluid (CSF) to drain into the superior sagittal sinus is called the arachnoid mater.

To add, the arachnoid mater is the middle of three layers that make up the meninges, or membranes, that surround the spinal cord and brain.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
