They are called as bursae. They reduce the friction of the muscle tendons.
Bursa or Bursae
Bursa itself does not have a direct blood supply; instead, it receives nourishment through adjacent synovial membranes and surrounding tissues. The vascular supply to a bursa typically comes from nearby arteries that supply the joints and muscles. This indirect blood supply helps maintain the bursa's function in reducing friction between moving structures, such as tendons and bones.
Each sac contains a small amount of synovial fluid, a clear liquid that acts as a lubricant.
A pseudo bursa is a collection of fluid that forms adjacent to a joint as a result of chronic inflammation or injury, rather than being an actual bursa. It can mimic the appearance and symptoms of a true bursa but lacks a synovial lining and is not anatomically a bursa.
in the hip or shoulder joints
They are called as bursae. They reduce the friction of the muscle tendons.
In joints
Fibrous connective tissue forms on the bursa. This type of tissue prevents friction within the joints. The plural of bursa is bursas or bursae.

it is called the bursa
Bursa sacs are both the shock absorbers and the ball bearings of the musculoskeletal system. They disperse forces from blows on bony prominences and reduce friction where tendons or ligaments are in frequent motion. A bursa sac functions as a gliding surface to reduce friction between tissues of the body. The plural of bursa is "bursae". There are 160 bursae in the body. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees.

ooo ya that's bad ive had it on my butt! Yes. The little sacs that get inflamed (bursa) are in the joints.
Cartilage is an anatomical cushion in synovial joints, like the knee. The combining form for cartilage is chondr-. A bursa is a fluid filled cushion near a joint. The combining form for bursa is burs-.
Bursae function to cushion joints so that bones don't wear down from rubbing against each other.
A bursa (plural bursae) is a fibrous, fluid-filled sac found near synovial joints that helps decrease friction near a joint.
