SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane (sarcolemma

our bones to completely harden. The building of bones happens throughtout our lives. We are born with about 300 soft bones. During childhood and adolescence‚ the cartilage grows and is slowly replaced by hard bone. Some of these bones later fuse together‚ so that the adult skeleton has 206 bones. Bones are composed of two types of tissue. 1. A hard outer layer called cortical (compact) bone‚ which is strong‚ dense and tough. 2. A spongy inner layer called trabecular (cancellous) bone.

The Neglected Subject Slowly‚ over the years‚ studying the humanities has become more and more neglected. Slowly‚ science‚ technology‚ medicine‚ and engineering has dominated jobs and the school curriculum all over the world. The humanities has become like a dead language‚ unknown and forgotten. We fail to realize that without studying English‚ history‚ art‚ and culture‚ society cannot function. Some people argue that studying the humanities does not help society. The jobs related to the humanities

Section 1: Identification and evaluation of sources The question of this investigation is “What explains King Leopold II´s poor treatment of his subjects in Congo Free State?”‚ and it will investigate what could contribute to explaining how and why King Leopold II of Belgium were able to treat his subjects in Congo so poorly. There could of course be several contributing factors that explains King Leopold II´s poor treatment‚ however‚ in this investigation‚ the focus will be on the factors that gave

FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

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

Minimum Wage Fireworks were lit once the announcement surfaced the internet that President Obama stated‚ “Tonight‚ let’s declare that in the wealthiest nation on Earth‚ no one who works full-time should have to live in poverty.” (Obama) He was looking to raise minimum wage during his State of the Union address. The average middle class person would be elated that minimum wage was going to rise. The amount of increase would depend on your location. I was one of those people would were excited
