Muscles are a Band or bundles of tissue in either the human body ‚ or animal body that allow contraction for movement. There are many muscles in the body.

You have Muscles in your head‚ arms‚ legs‚ just about anywhere you can think of and as we progress in life and become of age our muscles may grow and get stronger ‚ or may deteriorate.

Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres. Type 1 fies take approximately 110 ms to reach peak tension when

Building muscles may be the purpose of many people and for doing so‚ they usually start with an intense weight training. What most of them don’t know‚ is that for building muscles‚ the balance is only 20% weight training and 80% a proper diet.

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
