Question

What happens if the joint that helps in exercising biceps and triceps are replaced with the joints in the cranium?

• A. The movement around elbow remains the same.
• B. The forearm can move around 360 degrees.
• C. The forearm can move back and forth.
• D. Movement around elbow will not be possible.

Answer 1

The correct option is D Movement around elbow will not be possible.

$\bullet$ Hinge joint in the elbow helps us to bend our arms.
$\bullet$ Elbow joints can move 180 degrees making back and forth movement of the arm possible.
$\bullet$ Bones in the skull are joined with fixed joints. Fixed joints are fibrous joints that are immovable.
$\bullet$ If elbow joints are replaced with skull joints, it makes the elbow movement impossible.
