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.
Synovial fluid sacks are small fluid-filled sacs found in joints, called bursae, which help reduce friction between bones, tendons, and muscles during movement. These sacks contain synovial fluid, which lubricates the joint and provides cushioning to prevent wear and tear.
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 membranes line the inner surface of joint capsules and produce synovial fluid. The synovial fluid is contained within the joint capsule, forming a lubricating fluid-filled space that provides nourishment to the articular cartilage and helps reduce friction between the joint surfaces during movement.
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.

A bursa.
A synovial joint exhibits a joint cavity. This cavity is filled with synovial fluid, which helps reduce friction between the articulating surfaces of the bones within the joint. Examples of synovial joints include the knee and shoulder joints.
