Endocrine system regulation slowly happens but produces long-lasting effects, whereas nervous system regulation quickly takes place with short-term effects.
Endocrine system can regulate many things in the body that control the metabolism. The effect shouldn't be instant, but it should be good for long term effect. Nervous system need a much faster reaction because it responsible for "fight or flight" reaction. A slow nervous system will cause the organism caught by predator easier.
 
        
             
        
        
        
Answer:
Combined decrease in sarcomere length.
Explanation:
Sarcomere is the functional unit of the striated muscle tissue. The units get repeated between the two Z lines. The striation under the microscope is shown by the sarcomere.
Actin and myosin protein plays an important role in the muscle contraction. The individual length of the thick (myosin) and thin (actin) filament do not changes and slide over one other. But the sarcomere overall length decreases that result in muscle contraction.
Thus, the answer is combined decrease in sarcomere length.
