Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

Lab 3 – Skeletal Muscle Physiology Introduction Skeletal muscles are composed of hundreds to thousands of individual cells‚ each doing their share of work in the production of force. As their name suggests‚ skeletal muscles move the skeleton. Skeletal muscles are remarkable machines; while allowing us the manual dexterity to create magnificent works of art‚ they are also capable of generating the brute force needed to lift a 100-lb. sack of concrete. When a skeletal muscle from an experimental

degeneration of muscles is causes by progressive damage and loss of muscle cells with linked to weakness. There is a decrease in the force which muscle can exert. Our muscle become tired and it will cause of muscle fatigue. There are common causes why our muscles become weak. Lack of use is the most common causes of muscle weakness. Muscles become chunky and more floppy because muscles are not used then the fibers within the muscles partially replaced with fat. Aging is another factor of muscle degeneration

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
