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

HOW TO GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the

Anatomy of Muscle Cells There are three types of muscle tissue in the human body. These muscle tissues are skeletal muscles‚ smooth muscles and cardiac muscles. Each of these muscle tissues has it very own anatomical makeup‚ which vary from muscle to muscle. The muscle cells in a muscle are referred to as muscle fibers‚ these fibers are skeletal muscle fibers‚ smooth muscle fibers and cardiac muscle fibers. The anatomy of a skeletal muscle fiber is formed during embryonic development
