MICROANATOMY

Detailed explanation-1: -Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity .

Detailed explanation-2: -The movable joint is also called a synovial joint due to the presence of lubricating fluid called synovial fluid. Synovial fluid allows the smooth movement of bones at the joints.

Detailed explanation-3: -Functionally the three types of joints are synarthrosis (immovable), amphiarthrosis (slightly moveable), and diarthrosis (freely moveable).

Detailed explanation-4: -Synovial joints, also known as movable joints, refer to the joints that are capable of moving in a variety of directions (allow mobility). Such examples include the knee joints, elbow joints, wrist joints, shoulder joints, hip joints and ankle joints.

Detailed explanation-5: -Synovial joints allow bones to slide past each other or to rotate around each other. This produces movements called abduction (away), adduction (towards), extension (open), flexion (close), and rotation.
