Vitamin B12 is one of the most common topics I get asked about for those interested in a plant-based diet.

The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a personâs body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.uscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function of movement is the muscular systemâs second function: the maintenance of posture and body position.
Muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood.The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.Here are more details about the structure and function of each type of muscle tissue in the human body.1. The Human Body Has Over 600 Skeletal Muscles That Move Bones and Other Structures Skeletal muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system.keletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions. Here are more details about the structure and function of each type of muscle tissue in the human body.
