What is the differences between myocardial muscles and skeletal muscles?
Skeletal muscles: packed together, attach to, and cover the skeleton. obvious striations. VOLUNTARY muscles. contract rapidly but TIRE EASILY. responsible for overal body motility. extrememly adaptable (can exert forces from only onces to 70 lbs) Cardiac (myocardial): only in the heart. striated and NOT VOLUNTARY. contracts at a steady rate. contolled by nervous system and bodily changes. ONCE YOU LOSE IT, ITS GONE FOR GOOD. CAN'T FATIGUE. has to have stimulus great enough to stimulate all of the muscles of none will contract (where as skeletal muscles can be forced into twiches where only a small part of the muscle will contract)
When a sea star contracts different muscles it changes the what?
Pressure
What is a graph illustrating the pressure and volume changes during one heartbeat called?
That graph is known as a pressure-volume loop. It is used in cardiology to assess cardiac function and to visualize the changes in pressure and volume within the heart during one cardiac cycle.
An electrocardiogram is a recording of electrical changes occurring in the myocardium during what?
Cardiac cycle
When does wood expand and contract?
Wood expands and contracts in response to changes in temperature and humidity.
What causes internal change in the work environment?

What are the various changes that occur in the body while playing football and due to acclimatization like changes in heart beat and metabolic rate and effect on cardiac muscles?
the
Detect changes of internal or external stimulus?
sensory receptors
What detects changes of internal or external stimulus?
sense of balance
What system senses changes in the internal and external environment so that the body can adapt to the changes.?
The nervous system.
What are the positive and negative changes after gastric bypass?
There will be cardiac changes. As there will slowly be less stress on the heart and vital organs, you should be able to move around better with ease.
How does the skeletal system enable us to move?
The skeletal system aides in human movement by giving the body a static and rigid shape. This basically gives the muscles 'something to pull on' so that they can move the rest of our body. Bones also offer protection and engagement for our internal organs.
