What is the function/importance of the muscular system?
Lera25 [3.4K]
<h2>╔═⋄═◇═◈═❖═✧═☆═✧═❖═◈═◇═⋄═╗</h2><h2 /><h2>➤ Answer </h2>

☆ The function of the muscular system to respond to information from the brain, and contract accordingly.

<h3>➤ Reason</h3>

✧ The nervous system is responsible for sending signals to the body to control it. Your nervous system can send electrical pulses to your muscles, which they respond accordingly, moving in what ever way your nervous system told it to. Your nervous system is controlled by your brain, and this is why you can control these movements. Say for example, when you move, your fingers, you are actually just sending electrical signals to your hands which cause your muscles to contract, making your finger move in a certain direction. The muscles are connected to your bones, which are connected to joints, allowing the bones to move in different directs when your muscles contract.

<h2>✧ Your brain is powerful.</h2><h2 /><h2>╚═⋄═◇═◈═❖═✧═☆═✧═❖═◈═◇═⋄═╝</h2><h2 /><h2 /><h2 /><h2 /><h2 />
