What causes skeletal and cardiac muscles to appear striated?
The myofibres cause skeletal and cardiac muscles to appear striated because they are cyndrical and long, extending across the entire surface of the muscle.
What type of muscle causes voluntary movement?
Striated (or skeletal) muscle
What is the muscle tissue that moves bones?
All your muscles contribute to moving your skeleton. Each muscle in your body is connected to another either by a tendon or ligament and moving one causes a chain reaction making the connecting muscles move as well.
What causes uncontrollable muscle movements?
Involuntary muscle movement includes peristalsis in the GI tract and the beating of your heart. Generally involuntary muscles are smooth muscles (intestines, blood vessels), but the cardiac muscles are sometimes categorized as striated due to their structural similarities to skeletal muscles.
What is the purpose of the muscle system?
Muscles allow the body to move. There is your basic answer. To give more information, you have three types of muscles. They are skeletal, smooth, and cardiac muscles. Your skeletal muscles are attached to your skeletal system as the name implies. The smooth muscles are all muscles that aren't skeletal muscles or cardiac muscles such as your diaphragm, which controls breathing, and stomach, which causes the stomach's contraction and expansion. Your cardiac muscles control the heart's beat. So as far as the purpose of the muscles system, is to keep you alive. Without it, you could not move, digest food, or circulate blood throughout your body.
What is the purpose of the muscled system?

Without it, you could not move, digest food, or circulate blood throughout your body.
How many types of muscles are there in humans?
There are three types of muscles:Skeletal muscle- Muscle of exterior (ex. triceps, biceps)Smooth muscle- Muscle of interior organs (ex. lungs, stomach)Cardiac muscle- Muscle of heart (ex. heart)
Does a skeletal muscles react quickly and tire easily?
Yes. You are correct. The rapid movement causes them to use more energy and build up more lactic acid so they tire faster.
What is an illness condition related to the muscular system?
Muscular dystrophy is one. It is typically an inherited disorder that causes degeneration of the skeletal muscles.
What are the drugs used in legal execution by injection?
Sodium thiopental: ultra-short action barbiturate, an anaesthetic agent capable of rendering the prisoner unconscious in a few seconds.Pancuronium: non-depolarizing muscle relaxant, causes complete, fast and sustained paralysis of the skeletal striated muscles, including the diaphragm and the rest of the respiratory muscles; this would eventually cause death by asphyxiation.Potassium chloride: stops the heart, and thus causes death by cardiac arrest.Other drugs may apply in different countries or states.
The characteristic reddish brown color of skeletal muscle comes from which substance?
myoglobin gives the muscles the reddish brown color
How does the appearance of smooth muscle differ from that of skeletal mucsle?
They are all in different places. Skeletal muscles are striated and are the muscles that are in voluntary control. These include biceps(arm), pectoralis major(chest) and other muscles that you can move. These muscles are striated and has many nuclei. Smooth muscles are not striated and are the muscles that are not in voluntary control. These include organs and blood vessels, excluding heart. These muscles are unstriated with one nucleus. Smooth muscles has only one nucleus. There is only one place where cardiac muscle is found: the heart. Also called myocardium, this muscle is striated and has one nucleus. Cardiac muscle also contains intercalated disc, which acts as a junction between the two muscle cells.
