Before the motor neuron cone arrives the muscle fiber‚ AChR clusters are formed in the middle section of a muscle fiber. When the growing nerve cone attaches the muscle fiber‚ Agrin activates Lrp4‚ which then binds to the receptor tyrosine kinase MuSK‚ through this binding MuSK is phosphorylated and starts to form the neural and aneural AChR clustering (Burden 2011). Morphologic differences in the pre- and/or postsynaptic part of the NMJ can be a hint of a certain disease. In the following figure

factors affect muscle fatigue? Introduction: In this experiment muscles will be tested with weight‚ to see if weight is truly a factor in muscle fatigue. Muscle fatigue is the muscle’s ability to contract exert its normal strength due to physical stress upon it. The structure of a muscle include a thin layer called epimysium which surrounds the entire muscle‚ deeper to the epimysium is the perimysium. This layer contains fascicles which are bundles of muscle cells. In between the muscle cells are endomysium

1. Describe four important points and why they are important. Harden (2011) explains the importance of therapeutic hypothermia and the benefits of implementing this intervention post-cardiac arrest. Therapeutic hypothermia is used to potentially decrease or prevent any kind of neurologic deficit that could occur post - arrest from decreased perfusion and oxygenation to the brain. The benefits of starting this are exponential and “…decreases free radical production‚ inflammatory pathways‚ cellular
