Our muscular system is a strong framework of muscles that allows us to move both inside and out. It also maintains the posture of the body, and the flow of platelets all through the body. It includes 700 muscles and makes up around 40% of the complete body weight. These muscles are connected to bones, veins, and other inner organs of our body and are predominantly made out of skeletal muscles, tissue, ligaments, and nerves.
Movement and Body Muscles
Humans have an amazing range of movements via various muscles of their bodies. The nervous system orders the body muscles to contract. All living things show movements in response to the changes in the surrounding environment. Every movement in our body occurs because of the muscle contractions and can be found in almost every organ of the body, be it your heart, intestines, or blood vessels. In these organs, muscles work by moving the substances all through the body. Muscles are classified into three basic types and are fundamentally arranged depending on their contractions and movements. These muscles are the
- Skeletal muscles
- Smooth Muscles
- Cardiac Muscle
Voluntary Muscles and Involuntary Muscles
Voluntary muscles are those which work as indicated by one’s mind or are under control, though involuntary muscles are not heavily influenced by one. Biceps muscles, alimentary, respiratory, and the urogenital tracks are home to many voluntary muscles such as locomotor muscles as well as the abdominal muscles are also found there, while muscular strength, ear muscles, Diaphragm are the instances of the compulsory or involuntary muscles. Both muscles can be differentiated based on their functions, structures, and movements as described below;
The voluntary muscles are long and cylindrical and are unbranched muscles while the involuntary muscles are small in size and have a spindle shape.
Voluntary muscles require high energy to work and are found attached to the bones while the involuntary muscles unlike the voluntary muscles don’t require high energy to operate and are located in walls of the internal body organs.
The movement of the body parts and movement in the body is managed by the voluntary muscles, while the involuntary muscles are responsible for the movement of internal body organs by moving and transferring the body fluids and meals in the digestive tract.
The voluntary muscles include the skeletal muscles and are associated with bones movement while the involuntary muscles include smooth muscles and cardiac muscles as it transfers the blood cells in the body.
