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

Muscles are all made of the same materials‚ a type of flexile tissue of thousands narrow tissues that make up all the muscles. There are three types of muscle tissue in the human body which are Cardiac‚ Smooth and Skeletal Muscles. Cardiac Muscles are muscles that conduct‚ forced‚ being completely in heart‚ responsible for pumping activity of heart‚ very heavy and solid. Smooth are non band‚ not under voluntary force found in comfortable organs of body accountable for growth like absorption of food

The Primordial Soup Hypothesis‚ otherwise known as "The Primordial Soup Theory‚" was developed by the Russian chemist A.I. Oparin and English geneticist J.B.S. Haldane. Oparin & Haldane(1920) formed this idea separately though. In this theory‚ the basic aspects of life all came from simple molecules that formed in the atmosphere with the addition of oxygen. They believed that Earth had a chemically reducing atmosphere. This produced monomers. These monomers formed a "soup‚" that developed organic

How to Build Muscle 1. Develop a Technique Learn the proper way to do each exercise whether it is pushups or weight training. Developing a solid technique will maximize the workout and strengthen the muscles. Strength training is a method that should not be overlooked because it allows a person to start with minimal weight and add more weight as they progress. This builds more muscle which in turn builds more strength. 2. Machines vs. Free Weights Those weightlifting machines

human brain has tripled in size‚ with most of the growth being seen in just the last two million years. Although many explanations for the growth of the human brain have been presented‚ one hypothesis that proves to be most accurate is the Social Brain Hypothesis as presented by Robin I.M. Dunbar. This hypothesis attempts to explain the cause in brain size evolution by attributing it to social relations and social changes happening in early human populations. Homo habilis‚ the first of our genus Homo

The Interaction Hypothesis (IH) is attributed to Michael Long (1981) is based primarily on the work of Stephen Krashen and Evelyn Hatch. Long emphasized the importance of comprehensible input that was central to Krashen’s Input Hypothesis but claimed that this input was most likely to be acquired during interactions which involved discourse modifications. This claim supported that of Hatch (1978) who showed a direct link between the way learners acquired a second language (l2) and the interactions

For me a long term effect of having cancer is extreme fatigue. This makes it harder for me to focus during class‚ stay awake long enough to complete mounds of homework‚ and enjoy the social aspect of school.
