What is each organ’s function in this body system?
· Rectus Abdominis The “six pack” muscle that bends the body forward and pulls the abdomen inward. This is how people get abs.
· Biceps Brachii Helps bend your arm at the elbow.
· Flexor Capri Radials Helps bend the wrist
· Triceps Brachii­ straightens your arm at the elbow
· Pectoralis Major Pulls the arm forward and in toward your body, and twists it.
· Sartorius Turns the leg around and bends it at the hip and knee.
· Gastrocnemius (Calf Muscle) bends the foot downward when you walk or stand on tiptoe.
· Extenros Digitorum Longus Straightens the toes and helps lift the foot upward.
· Quadriceps Femoris (Thigh Muscle) Made up of four large muscles that straightens the knees during running, walking, or kicking.
· Deltoid Shapes the shoulder, and swings your arm backward and forward or raises it sideways.
· Sternocleidomastoid Bends your head forward or makes the head tilt.

What can go wrong with the Muscular system?
a) Botulism is a severe food poisoning caused by a toxin produced by some type of bacteria that are sometimes present in foods that are not properly canned or preserved. It can prevent a person to control their body and it could cause breathing to fail.
b) Muscular Dystrophy Inherited muscular disease where a person’s muscles moderately and irreversibly deteriorate. It causes weakness and can lead to complete disability.
c) Myasthenia Gravis Affects the muscles for the neck, throat, lips, tongue, face, and eyes. This disease causes a person’s muscles to become weak because of antibodies attacking and damaging the body’s normal cells.

What would happen to the individual if something went wrong with the Muscular system?

a)
If an individual got the Botulism disease, they would be unable to move parts of their body because of the food poising. They would end up in a hospital and have to be put on a breathing tube because their breathing would eventually fail.

b)
If an individual got the Myasthenia Gravis disease, he or she may need help doing certain things. For example, if some thing happened to their throat muscle, they would have to be put on a machine that feeds them food through a tube.

c)
If an individual gets the Muscular Dystrophy disease, their muscles would deteriorate and cause that person to lose complete control of their body. They would be stuck in a wheel chair or in a hospital bed.



9)
Could a person survive without the muscular system?
A person would be able to survive without this muscle but that is only if they would want to be a vegetable. In order to live a normal life without being taken care of is if you have the muscular system. The muscles help you breathe, help move food through the body, and help you walk and talk. So, someone would be able to live without muscles but they would be hooked up to a machine that helps you breathe and eat.
