Final Answer:
Synovial joint is freely moveable with one exception, thus the correct option is 3) Synovial joint
Step-by-step explanation:
Synovial joints are freely moveable, allowing a wide range of motion due to the presence of a synovial cavity and lubricating synovial fluid.
However, the exception lies in the temporomandibular joint (TMJ), which is a synovial joint with limited mobility. The TMJ permits actions like opening and closing the mouth but has restrictions compared to other synovial joints.
Synovial joints are characterized by the presence of a joint capsule, synovial membrane, and articular cartilage. The synovial fluid within the joint cavity reduces friction and facilitates smooth movement.
Typically, synovial joints exhibit various movements, including flexion, extension, abduction, adduction, rotation, and circumduction. The versatility of synovial joints makes them crucial for functions like walking, running, and grasping objects.
However, the TMJ, found in the skull's temporomandibular region, deviates from the typical synovial joint mobility. This exception ensures stability in the jaw's movements while still allowing essential actions for speaking, eating, and facial expressions.
In summary, synovial joints are generally freely moveable, but the TMJ stands out as an exception with limited mobility within the category of synovial joints.
Synovial joint is freely moveable with one exception, thus the correct option is 3) Synovial joint
