A motor neuron‚ a nerve ending that is attached to a muscle fiber in Petzold’s huge bicep‚ sends a message to contract. This message goes to the neuromuscular junction‚ which is the connection between the actual nerve fiber and muscle fiber. As the message to contract reaches the terminals a neurotransmitter‚ a chemical messenger for the body‚ is released into the gap between the terminal end‚ and the sarcolemma and motor end plate called the synaptic cleft. The particular neurotransmitter is called

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

HOW MUSCLES GET THE ENERGY THEY NEED TO WORK 1) Muscle needs energy to contract and as stated previously the ‘universal energy currency’ of living systems is ATP (adenosine triphosphate). This is largely produced within mitochondria‚ organelles which are often referred to as the ‘powerhouse’ of the cell. The ATP that results is used to provide the power for the muscle fibres to contract. Contraction itself (i.e. actual shortening movement) occurs when a bond is broken between ATP and one of its

Simple Stimulus Learning Introduction According to Terry (2006) “stimulus learning is a relatively permanent change in behavior‚ or behavior repertoire which occurs as a result of experience.” Since knowledge itself‚ in the mind or in the brain‚ is not straight discernible‚ behavior transforms are required to present objective facts that have taken place. Learning includes the potential for a change in behavior‚ to be demonstrated when conditions prompt the display of this new knowledge

Children and muscle building programs‚ a safe choice? The importance of exercise in childhood development is beyond any discussion and we all realize that kids are more and more engaging in a sedentary lifestyle much like adults. So‚ it is very important to educate your child in healthy habits and to help develop a workout routine that is suitable for him or her. The question that is posed in this article is: should a bodybuilding workout be included in that routine? To start‚ let us define

voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction. It is generally accepted that muscle fibre

INTRODUCTION An electronic muscle stimulator is a circuit designed to stimulate nerves of that part of the body by attaching electrodes. It is used to revive frozen muscle that impair movement‚ it aid in building up muscles and it also helps in removing cellulites in the body EMS causes adaption‚ i.e. training of muscles fibers and can be used as a therapeutic tool. In medicine it is used for rehabilitation purposes‚ for instance in Physical therapy in the prevention of disuse muscle atrophy which can
