The major types of muscle systems are the skeletal muscles, cardiac muscles and smooth muscles, explains Healthline. The skeletal muscles are voluntary muscles, whereas the smooth and cardiac muscles are involuntary ones.Continue Reading
The three types of muscles work to move various parts of a person's body, says Healthline. Of these, the skeletal muscles are voluntary and move when they receive signals via the nervous system. These muscles, which are attached to the skeletal system, contract and expand to allow a person to move the limbs of his body with conscious effort.
The cardiac muscles are involuntary and usually set up a steady pulsing that pumps the blood all across the body. The walls of the heart are made up of these cardiac muscles. Healthline explains that these muscles receive signals from the brain through hormones and enzymes and also send electrical impulses that contract the heart.
Another set of involuntary muscles are the smooth muscles, which comprise the walls of the hollow organs of the body, such as the respiratory tract and blood vessels. They move in wavelike motions and help pass food down the gullet and perform other important functions. These muscles mostly move without a person's conscious effort, states Healthline.Learn more about Muscles
According to the Fayette County Public Schools, the breakdown of adenosine triphosphate (ATP) in a chemical reaction with water provides energy for skeletal muscles to contract. Since the amount of ATP stored in muscles is small, metabolic pathways that generate new ATP must be activated for continued muscle contraction. These pathways are either anaerobic (in the absence of oxygen) or aerobic (in the presence of oxygen).Full Answer >
The biceps are classified as skeletal muscles because they attach directly to the skeleton. According to Healthy Living, they are attached to the skeleton by tendons and are controlled voluntarily. As explained by education.com, skeletal muscles generally work in pairs; one muscle works in combination with an antagonistic muscle to move a joint such as the elbow or knee.Full Answer >
Muscular strength is the highest amount of effort exerted by the muscles of the body in order to overcome the most resistance in a single effort. A large part of muscle strength is endurance, which is the muscles' ability to repeat the contraction for a longer period of time before it becomes exhausted.Full Answer >
The muscular system consists of 650 muscles and it supports the movements required to walk, talk, eat and stand. It makes up more than 40 percent of the body’s total weight. The muscular system controls daily functions, maintains posture and circulates blood. It is divided into three types of muscles: skeletal muscles, smooth muscles and cardiac muscles.Full Answer >
