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

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

Richard Bone * ------------------------------------------------- Richard Bone is sort of the key to the whole collection of "Spoon River Anthology" because it details the epitaphs that he (being Edgar Masters) was able to craft knowing the true nature of the townspeople he commemorates. It was Masters’ job to write the epitaphs as it was Richard Bone’s job to write what they wanted on the epitaphs‚ which are probably not a real reflection of the lives they lead - just the image of themselves

Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

Bone Marrow Biopsy Introduction Bone marrow is the spongy material found in the center of most large bones in the body. The different cells that make up blood are made in the bone marrow. Bone marrow produces red blood cells‚ white blood cells‚ and platelets. Along with a biopsy (the sampling of mostly solid tissue or bone)‚ an aspiration (the sampling of mostly liquid) is often done at the same time. * Why the procedure is performed: A bone marrow aspiration and biopsy procedure is done for
