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

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _energizing the power stroke of the myosin cross bridge________________________ 2. _disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke_________________ 3. _energizing the calcium ion pump; transporting calcium___________________ 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called _hydrolysis________________________
