Where are fixed joints located in the body?

The human body does not have any fixed joints. All joints in the body exhibit varying degrees of movement. These joints are categorized based on the type and extent of movement they allow:

1. Synarthrosis (Immovable Joints): These joints have no movement and are firmly held together. They are found in the skull and some areas of the face.

2. Amphiarthrosis (Slightly Movable Joints): These joints have limited movement and are connected by cartilage. Examples include the joints between the vertebrae in the spine and the joints between the long bones in the wrist and ankle.

3. Diarthrosis (Freely Movable Joints): These joints are the most common and allow the greatest range of movement. They are characterized by a synovial membrane that lines the joint and produces synovial fluid for lubrication. Examples include the joints in the limbs (e.g., shoulder, elbow, knee, hip), as well as the joints of the fingers and toes.

In summary, there are no fixed joints in the body, but there are immovable (synarthrosis) and limited-movement (amphiarthrosis) joints in addition to freely movable joints (diarthrosis).
