The joints between the carpal bones in the ankles and wrists are known as Gliding Joints (a type of synovial joint). These joints work by allowing the bones to slide over each other, allowing smooth movements in multiple directions.
I believe you're looking for the term "synovial fluid."
Synovial Membranes
Cavities with spaces within joints are called synovial cavities. These are found in synovial joints, which are characterized by a fluid-filled space that allows for smooth movement between the articulating bones. The synovial fluid within these cavities acts as a lubricant, reducing friction and providing nourishment to the cartilage. Examples of synovial joints include the knee, elbow, and hip joints.
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.
Synovial fluid is a thick, stringy fluid found in the cavities of synovial joints. With its egg-like consistency (synovial comes from Latin for "egg"), synovial fluid reduces friction between the articular cartilage and other tissues in joints to lubricate and cushion them during movement.
Synovial fluid is contained in the synovial membrane.
The joints found between the carpals are inter-carpal articulations and the mid-carpal joint.
Synovial fluid is the lubricant between the ends of bones.

Synovial Membranes
The name of the membrane surrounding the joints is called synovial membrane.
Bursa is not all tissue. The bursa is a small sac filled with fluid. It is lined by a membrane called the synovial membrane. Bursae are the cushions between your bones, and they are found between most joins in the body.
Synovial joints are found between most of the long bones in the body.
Cavities with spaces within joints are called synovial cavities.

A bursa (plural bursae) is a fibrous, fluid-filled sac found near synovial joints that helps decrease friction near a joint.
