order for a muscle to contract requires a nerve impulse to arrive at the neurotransmitter junction. This then causes a release of acetylcholine (ACh) from the presynaptic terminal. By binding with its receptors on the membrane of the muscle fiber‚ which opens sodium channels generating an action potential that spreads through the length of the fiber‚ stimulating release of calcium from the sarcoplasmic reticulum. Calcium is what activates the contractile mechanism‚ causing the muscle fiber to shorten

When we’re sick we all use one thing a lot; facial tissues. We use them without even thinking about how they’re made or what was needed to make them. We just blow our noses and throw them away.

CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)

During a Muscle Contraction The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals‚ diffuses across the synaptic clef and binds to (receptors) on motor end plate. Then
