Human Anatomy and Physiology - Joints and Body Stability Quiz

Synovial joints have a wide range of movement due to the presence of a synovial cavity and lubricating synovial fluid.

Synovial fluid lubricates the joint surfaces, reducing friction and allowing smooth movement between bones.

Flexion is the term for bending a joint, reducing the angle between the bones and bringing them closer together.

The triceps brachii muscle is primarily responsible for extending the forearm at the elbow joint.

The skeletal system does not synthesize hormones; its functions include support, protection, movement, and blood cell production.

The femur is the medical term for the thigh bone, the longest and strongest bone in the human body.

The knee joint is a hinge joint, allowing primarily flexion and extension movements.

The clavicle is the medical term for the collarbone, a long bone connecting the shoulder to the chest.

The radio-ulnar joint enables rotation of the forearm, allowing for movements like supination and pronation.

The scapula is not part of the axial skeleton; it is a flat, triangular bone forming part of the shoulder.

The thumb joint is an example of a saddle joint, allowing for a wide range of movements in multiple planes.

Hyaline cartilage covers the ends of bones in synovial joints, providing a smooth surface and cushioning during movement.

The ACL (Anterior Cruciate Ligament) is a key ligament in the knee, providing stability and preventing excessive forward movement of the tibia.

The pivot joint between the atlas and axis allows rotational movements, such as nodding the head.

The ACL (Anterior Cruciate Ligament) connects the femur to the tibia, providing stability to the knee joint.
