Final answer:
2. false The statement that a static splint is used to allow for mobility is false. Static splints immobilize joints to aid healing, while the stability of a joint is inversely related to its mobility. Partly movable joints like those between the vertebrae allow for limited movement, enhancing stability.
Step-by-step explanation:
The statement 'A static splint is used to allow for mobility' is false. Static splints are designed to immobilize a joint to promote healing and provide support and stability. Mobility in joints can vary, with some joints such as the shoulder allowing a wide range of motion, making them less stable, and others like the carpal bones being more stable and less mobile. Partly movable joints, like those between the vertebrae, allow only a little movement, contributing to the stability of the spine.The articulating surfaces of bones at stable types of joints are strongly united to each other, providing stability but little to no mobility.
These include most of the joints of the skull, which protect the brain, and the lower leg joints that provide support while standing. Conversely, freely movable joints of the appendicular skeleton, like the shoulder, are not directly united and thus allow for significant movement to facilitate activities such as kicking, fork-picking, or dancing, at the cost of stability.A static splint is used to immobilize a joint, not to allow for mobility. Therefore, the statement is false.
