Synovial fluid plays a crucial role in reducing friction within the synovial joint. It acts as a lubricant, allowing smooth movement between the articulating surfaces of the joint. This fluid also helps to nourish and protect the cartilage within the joint, improving its metabolism and overall health. Additionally, synovial fluid contributes to the flexibility of the joint, allowing for a wide range of motion.

The skeleton is responsible for providing the framework on which muscles attach to facilitate movement, storing minerals essential for the body's proper functioning, and protecting vital organs. However, classifying the skeleton into groups is not a function of the skeleton.

Both A & B are types of bones. Irregular bones have complex shapes and do not fit into any other bone category, such as the vertebrae. Flat bones are thin and often curved, like the bones of the skull and ribs. The option "Tongue" is not a type of bone and is therefore incorrect.

Flat bones are found in the cranium. The cranium, also known as the skull, is made up of several flat bones that protect the brain. These bones include the frontal bone, parietal bones, occipital bone, and temporal bones. Flat bones are characterized by their thin, flat shape and provide protection and support for vital organs, such as the brain.

The base of the thumb contains a saddle joint. This type of joint allows for movement in multiple directions, resembling the movement of a rider on a saddle. The saddle joint allows the thumb to move in a wide range of motions, including flexion, extension, abduction, adduction, and opposition, making it highly mobile and versatile.

Flexion and extension are movements that occur at hinge joints. Flexion refers to the bending of a joint, while extension refers to the straightening of a joint. Hinge joints, such as the elbow and knee, allow movement in one plane, similar to the opening and closing of a door. Rotation and circumduction, on the other hand, are movements that occur at other types of joints, such as ball-and-socket joints or saddle joints.

The tibia and fibula are leg bones that are directly involved in kicking a football. The tarsals are a group of small bones in the foot that provide stability and flexibility, which are important for kicking. The femur is the thigh bone, which provides the power and strength needed for kicking. The other options do not include the tarsals, which are crucial for kicking, or include bones that are not directly involved in kicking a football.

Hyaline cartilage is commonly referred to as articular cartilage. It is a smooth and flexible type of cartilage that covers the ends of bones in joints. It provides a smooth surface for bones to glide over each other and helps in reducing friction and absorbing shock during movement. Articular cartilage is found in various joints in the body, such as the knee, shoulder, and hip joints.
