Some Synovial joints may have fluid-filled sacs called bursae.
amniotic sac
A fluid-filled sac that surrounds an embryo is called an amniotic sac. This sac contains amniotic fluid, which provides protection and cushioning for the developing embryo.
The fluid-filled bag of thin tissue that develops around the embryo is called the amniotic sac. It helps protect and cushion the developing embryo/fetus during pregnancy.
The vestibular sacs in your ears are filled with fluid, and the movement of fluid allows your "vestibular sense" to determine where your head is, and thus your general body position.
That space is called as sub arachnoid space. It is filled with cerebrospinal fluid.
Synovial Joint
The abdominal cavity contains major body organs such as the stomach, liver, intestines, and kidneys. This cavity is lined with a membrane called the peritoneum and is filled with a fluid called peritoneal fluid to help protect and cushion the organs.
amniotic sac
The extraembryonic membrane that forms a fluid-filled sac is the amnion. It helps protect and cushion the developing embryo by surrounding it with amniotic fluid.
A bursa.
A fluid-filled sac, such as a bursa or a synovial joint capsule, acts as a cushion to reduce friction between moving parts of the body. It helps to lubricate joints and facilitate smooth movement.
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-.
The amnion is a transparent sac filled with a colorless fluid that serves as a protective cushion during embryonic development .
A fluid-filled sac that surrounds an embryo is called an amniotic sac. This sac contains amniotic fluid, which provides protection and cushioning for the developing embryo.
The fluid-filled bag of thin tissue that develops around the embryo is called the amniotic sac. It helps protect and cushion the developing embryo/fetus during pregnancy.
The fluid-filled space surrounding the grana in chloroplasts is called the stroma. It contains enzymes, DNA, ribosomes, and organic molecules involved in photosynthesis.
The vestibular sacs in your ears are filled with fluid, and the movement of fluid allows your "vestibular sense" to determine where your head is, and thus your general body position.
