Bursa or Bursae
They are called as bursae. They reduce the friction of the muscle tendons.
The central cavity within the blastula is called the blastocoel. It is filled with fluid and is surrounded by a layer of cells called the blastoderm.
Having joints covered by a fluid-filled sac, called a synovial bursa, helps reduce friction between moving parts of the joint, provides cushioning and shock absorption, and aids in smoother joint movement. This fluid-filled sac also helps to distribute nutrients to the joint structures and remove waste products.
The hollow areas within the brain are called ventricles. There are four ventricles in the brain: two lateral ventricles, the third ventricle, and the fourth ventricle. These spaces are filled with cerebrospinal fluid which helps cushion and protect the brain.
A synovial fluid sac which is actually called a synovial bursa is a fluid-filled sac lined with synovial membrane with an inner layer of slimy fluid. This provides cushion between bones and tendons and/or muscles around joints. They also reduce friction between the bones.
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.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid
An air or fluid filled space is called a cavity. It can be found within the body, such as the nasal cavity or the pleural cavity within the chest. It can also refer to spaces in rocks, soil, or structures.

Synovial - the articulating bone ends are covered with articular cartilage, and enclosed within an articular capsule that is typically reinforced by ligaments externally. Internally the fibrous capsule is lined with a smooth synovial membrane that secretes synovial fluid.
A waterbed typically contains a fluid-filled cushion of water that provides support and comfort for sleeping. The water provides a unique sensation and can contour to the shape of the body, relieving pressure points and promoting better sleep.
