The skeletal system does not produce blood. This function is carried out by the hematopoietic system, which includes the bone marrow.

The femur, also known as the thigh bone, is the longest and strongest bone in the human body.

Fixed joints, also known as synarthroses, are not true joints because they do not allow for any movement between the bones they connect.

The primary function of muscles is to generate movement by contracting and relaxing.

Voluntary muscle is not a type of muscle tissue. Skeletal muscle is voluntary, meaning it can be consciously controlled.

The gluteus maximus, also known as the butt muscle, is the largest muscle in the human body.

The muscular system does not have a sensory function. Sensation is a function of the nervous system.

The sliding filament theory explains how muscles contract by describing the interaction between actin and myosin filaments.

Eccentric contraction is not a type of muscle contraction. It refers to the lengthening of a muscle under tension.

The primary function of tendons is to attach muscles to bones, allowing for the transmission of force and movement.

Tendons are not ligaments. They are fibrous cords that attach muscles to bones, while ligaments connect bones to bones.

Cartilage serves multiple functions, including reducing friction at joints, providing cushioning and shock absorption, and allowing for smooth movement of bones.

Bone cartilage is not a type of cartilage. Cartilage is a specialized connective tissue that does not contain blood vessels or nerves.

Bone growth and repair involve a combination of ossification, remodeling, and resorption, which work together to maintain bone health and integrity.

Sodium is not a mineral found in bones. Calcium, phosphorus, and magnesium are the primary minerals that make up bone tissue.
