Bursa or Bursae
The ventricles are fluid filled cavities of the brain.
FlexAbility
They are called as bursae. They reduce the friction of the muscle tendons.
Vacuoles
The fluid-filled sac that covers the yolk in an egg is called the vitelline membrane. It acts as a protective layer and helps to maintain the yolk's shape and position within the egg.
Ganglion cysts arise as outpouchings from fluid filled areas such as the fluid within the small joints of the wrist, or fluid within the sheath that surrounds the wrist tendons. When the fluid, called synovial fluid, leaks out from these spaces, it can become a cystic structure.
Some Synovial joints may have fluid-filled sacs called bursae.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid

A bursa (plural bursae) is a fibrous, fluid-filled sac found near synovial joints that helps decrease friction near a joint.
All joints have a membrane called the synovial membrane. It contains synovial fluid; therefore, all joints contain a fluid.synovial Joint

Those holes are called Ventricles, and together are part of the ventricular system. There are 4 ventricles altogether in the brain: 2 lateral ventricles (right and left) a third ventricle and a fourth ventricle (names are not very original, but thankfully easy to remember).
