Skull crushers - aka supine or lying triceps extensions - work your triceps as your elbow bends and straightens, while your shoulder muscles stabilize your shoulder joint.
The name "skull crusher" derives from what can happen if you do them incorrectly.

Things to Avoid:

Overarching the Lower Back: Maintain a neutral spine throughout the exercise, avoiding excessive arching, which can strain the lower back.

Excessive Elbow Flaring: Keep your elbows relatively close to your head during the movement, preventing unnecessary strain on the shoulder joints.

Jerking Motions: Perform Skull Crushers in a controlled manner, avoiding sudden, jerky movements that may lead to injury.

Improper Range of Motion: Ensure you complete a full range of motion, lowering the weight towards your forehead or just above without compromising form.
