We have more than 600 muscles in our bodies. They pump blood throughout your body‚ and help you lift heavy things like backpacks‚ and textbooks. You could control some of your muscles‚ while others like your heart‚ have their own jobs without us thinking at all. Muscles are all made up of same material. A type of tissue like the material in a rubber band. Thousands or tens of thousands of small fibers make up all or each muscle in our body. There are different muscles‚ fibers‚ and contractions.

The Skeletal System The skeletal system is made up of bones‚ the joints where bones meet‚ and the connective tissues called cartilages that hold the bones together. The human skeleton is made up of 206 bones‚ and can be divided up into to two parts‚ the Axial Skeleton and the Appendicular Skeleton. (Adams et al.‚ pg. 4)(Boundless‚ 2013) Axial Skeleton The axial skeleton forms the main axis or core of the skeletal system. It consists of the skull‚ vertebral column‚ and thoracic cage. As noted by

The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins
