stimulation A. Describe briefly what you have done for this section (maximum 100 words). B. What are the observations that you have made? (maximum 150 words) The experiment was carried out by using the amplitudes as low as 0.00mA to locate the twitching. But volunteer was not able to feel any twitch response from the amplitude of 0.00mA to 6.5mA. But to be close to accurate we located the twitch response by using the amplitude of 10.0mA.

voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction. It is generally accepted that muscle fibre

Activity 1 – The Muscle Twitch and Latent 1) Define the terms skeletal muscle fiber‚ motor unit‚ skeletal muscle twitch‚ electrical stimulus‚ and latent period. Skeletal Muscle Fiber: Skeletal muscle cells that are composed of hundreds to thousands of individual cells that produce muscle tension. These fibers are what move our bodies and generate muscle tension/force that enables us to have manual dexterity. Motor unit: consists of one motor neuron and all of the skeletal muscle fibers that it

Title: Muscle twitch response and recruitment‚ summation and tetanus Exercise 1: The effects of nerve stimulation Objectives: 1. To explore the motor and sensory effects of electrical stimuli on a student volunteer‚ using the nerves of the forearm. 2. To examine the position where a largest muscular twich response with the lowest pulse current can be generated. This position is kept constant to determine results in exercises 2 and 3. Procedure: Refer to Human Biology Practical Manual

Stimuli on Simple Muscle Twitch. Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System. Nerves are in touch with muscle by motor end plates which convey a stimulus to contract. Muscle activity is not

What happens in diabetes? Lack of insulin or a resistance to insulin is known to have major metabolic effects. Food powers our bodies. When we eat food‚ most digestable carbohydrates are converted into glucose and rapidly absorbed into the bloodstream. We use this glucose for energy. However these carbohydrates cannot be utilized effectively and excess glucose cannot be stored in the liver. The glucose level in the blood increases but the cells of the body will be lacking of glucose and energy.

Photosynthesis (happens in chloroplasts in mesophyll cells) 1. Light dependent stage Happens in the grana of chloroplasts Light (energy) gets trapped by chlorophyll pigments (light energy converted to chemical energy) This energy used to turn ADP and Pi into ATP Energy used to split water (H2O) into Hydrogen and Oxygen The hydrogen ions get collected by NADP‚ which becomes NADPH The Oxygen is waste‚ and leaves! So‚ in this stage‚ water comes in. ATP and NAPDH come out‚ as does Oxygen.

Jim Heynens writer of What happen during the ice storm‚ shows a humans reaction during a challenging situation. The theme of this tale is kindness‚ a type of human nature ‚ in the story is showing a few boys saving the pheasants‚ instead of pounce on a pheasant or yell bang . The human nature can be represented by many forms‚ and in this story is by survival and limitless kindness. This story is an example of how a tough situation can influence a person’s decision making. For example when the

What Happens Next Caitlyn Smith I woke up early one day. The cave was dark and I could not see. I went outside to see if I could find mother‚ but she was nowhere to be found; I guess she went off somewhere without telling me. I’m looking around after just waking up and I see this creature. I don’t know what to do. He comes closer‚ what am I supposed to do? I saw him running towards me and I started getting scared. He grabbed a stick and threw it towards me as if to warn me that he was

REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force. 2. Independent
