Understanding the Muscular System: Types, Functions, and Energy Mechanics

The muscular system is an essential organ system that enables body movement through contraction and relaxation. It involves three main muscle types: skeletal (voluntary and striated), cardiac (involuntary and striated), and smooth (involuntary and non-striated). Skeletal muscles are attached to bones and allow conscious control, whereas cardiac muscle is exclusive to the heart. Smooth muscles operate in organs like the intestines and blood vessels. Muscles obtain energy from blood, which delivers energy-rich molecules, enabling movement and maintaining body temperature.

  1. Ch. 6 Section 2 The Muscular System

  2. an organ that relaxes, contracts, and provides force to move your body • they work constantly • examples- heart, digestive system, lungs 1. muscle

  3. voluntary- muscles you can control, tire much more easily than involuntary muscles involuntary- muscles you cannot control consciously (heart, digestive muscles) 2. Types of Muscles 3. Classifications of Muscles skeletal muscle cardiac muscle smooth muscle

  4. 4. skeletal muscle • most common type of muscle • attached to bones by tendons • striated or appear to be striped • voluntary

  5. 5. cardiac muscle • found only in the heart • striated or striped • involuntary

  6. 6. smooth muscle • found in intestines, bladder, and blood vessels • non-striated (not striped) • involuntary • slowly contract and relax

  7. when one muscle contracts, its pair relaxes • muscles always pull, never push • muscles become larger or smaller depending on how much you use them 7. How do muscles work? 8. How do muscles get energy? • blood carries energy-rich molecules to muscles • as the muscle works, movement (mechanical energy) and heat (thermal energy) are released • the heat produced allows us to keep our body temperature constant
