Muscle contractions tend to be smooth and vary in strengths‚ depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation. When a muscle is responding to a change in stimulus frequency‚ the nervous system will reach a greater muscular force when increasing the firing of motor neurons. This causes a wave or

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

April 2013 Muscle Growth DR. PAUL D. THOMPSON‚ a 60 year old marathon runner and chief of cardiology at Hartford Hospital‚ stood in front of a medical audience recently and began his talk with a story about himself. Hes had been lifting weights since he was 12 years old. Dr. Thompson is now a small and wiry with not a bulging muscle on him. He was speculated that he must have a genetic inability to build muscles‚ no matter how hard he works at it. But are his muscles healthy? Muscle researchers

Stimulus-Dependent Lab A motor unit is a motor neuron and the muscle fiber it controls. A whole muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become

In The Farming of Bones‚ Edwidge Danticat uses a unique point of view to place the reader into the story through the use of ‘you’ and common senses. By using the trigger word ‘you’‚ Danticat helps the reader connect to the story in two ways: emotionally and physically by describing common senses or feelings that one can relate to in their own life. Emotions are experienced by everyone on a daily basis in various degrees‚ depending how sensitive a person is. “At first you are afraid to step into the
