The depolarisation and repolarisation that takes place within a cell from that occurs gives rise to voltage of waveforms. With the human body each cell at this present time is generating electrical impulses like a voltage generator‚ which is a basic source of all the bioelectric potentials. With these bioelectric potentials they produce ionic voltages produced by the coordination of electrochemical activity within numerous cells. When the cells are in line the charges tend to migrate through the

Muscles attached to scapula: Levator scapulae origin is transverse processes of C1-C4‚ insertion at superior angle of scapula‚ it moves scapula and flexes neck. Pectoralis minor’s origin is ribs 3-5 and insertion at coracoid process of scapula‚ it depresses scapula and elevates ribs. Rhomboids Major and Rhomboids Minor’s origin at spinous processes T1-T4‚ insertion at medial border of scapula‚ they move scapula. Serratus anterior’s origin is at ribs 1-9‚ insertion is at medial border of scapula

Question: How do various factors affect muscle fatigue? Introduction: In this experiment muscles will be tested with weight‚ to see if weight is truly a factor in muscle fatigue. Muscle fatigue is the muscle’s ability to contract exert its normal strength due to physical stress upon it. The structure of a muscle include a thin layer called epimysium which surrounds the entire muscle‚ deeper to the epimysium is the perimysium. This layer contains fascicles which are bundles of muscle cells. In between

Introduction In creating a whole life concept for myself as I become an engineer was a little overwhelming for me at first. Reading The 7 Habits of Highly Effective People By Stephen R. Covey‚ really helped me to better understand what a whole life concept was and how to apply it to daily life. In Habit 1 Be Proactive I was introduced to the concentric circles model as seen Fig.1. Starting out with the circle of concern which includes worries fears such as national debt‚ nuclear war‚ health

Whole Grains What are whole grains? Whole grains are foods naturally coming from the entire grain seed. All grains start as whole grains‚ whether it stays that way depends on us. When they are growing in the fields the whole grain is the whole seed of the plant called the kernel. Whole grains are made up of three important parts; the bran‚ the germ and the endosperm. Before a food qualifies as whole grain it must have 100% of the kernel‚ which means all of the bran‚ germ‚ and endosperm must be

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
