Compare and contrast the contractile mechanisms and means of activation of skeletal and smooth muscles in the body

A. Skeletal muscles are primarily voluntary and attached to bones, while smooth muscles are involuntary and found in organs.
B. Both skeletal and smooth muscles contract through the sliding filament mechanism, but only skeletal muscles are controlled by the somatic nervous system.
C. Skeletal muscles use acetylcholine for activation, while smooth muscles rely on both neural and hormonal stimuli, including acetylcholine and adrenaline.
D. Smooth muscles contract more slowly and sustainably than skeletal muscles, which contract rapidly but fatigue quickly.
