In which of the following is synovial fluid found?

Correct option is A

The correct answer is (a) Freely movable joint.
· Synovial fluid is a viscous fluid found in the cavities of synovial joints, which are characterized by their freely movable nature. These joints include the knee, elbow, shoulder, and hip joints among others. Synovial fluid helps to reduce friction between the articulating surfaces of bones during movement and provides lubrication to ensure smooth joint motion.
Details on other options:
· Cartilaginous joint: Cartilaginous joints are connected by cartilage.They allow for limited movement and are found between vertebrae in the spine and between the ribs and sternum (costal cartilages).
· Fixed joint (Fibrous joint):Fixed joints, also known as fibrous joints, are connected by fibrous tissue.They do not allow for movement and provide structural stability.
· Fibrous joint:Fibrous joints, as described above, are joints connected by fibrous tissue.They are also known as fixed joints and do not have a synovial cavity or synovial flu.
