Pholcids do indeed have short fangs, which in arachnological terms is called uncate because they have a secondary tooth which meets the fang like the way the two grabbing parts of a pair of tongs come together.

The areas in the brain that contain this fluid are called ventricles. Sometimes CSF needs to be drained away from the ventricles. External ventricular drainage (EVD) is a temporary method of doing this. The EVD system uses a catheter (a thin, plastic tube), which is placed in the ventricle of the brain. This is connected to a drainage system outside the body (see diagram). The drainage system works by using gravity.
