Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

Nutrition A Muscle Contraction Muscle Contraction is part of an organ in the body that is tensive. It may have a process of tensions that may be developed with muscle tissues. Contraction can be a meaning of shortening or long. Muscle Contraction can also produce a muscle cell that is for movement of the body. Myosin and Actin is an interaction protein to Muscle Contraction‚ it can be changed by shape but not by volume. Skeletal Muscle contraction is produce by heat. The muscles may receive signal

Premium Nervous system Muscle Axon
A motor neuron‚ a nerve ending that is attached to a muscle fiber in Petzold’s huge bicep‚ sends a message to contract. This message goes to the neuromuscular junction‚ which is the connection between the actual nerve fiber and muscle fiber. As the message to contract reaches the terminals a neurotransmitter‚ a chemical messenger for the body‚ is released into the gap between the terminal end‚ and the sarcolemma and motor end plate called the synaptic cleft. The particular neurotransmitter is called

INTRODUCTION An electronic muscle stimulator is a circuit designed to stimulate nerves of that part of the body by attaching electrodes. It is used to revive frozen muscle that impair movement‚ it aid in building up muscles and it also helps in removing cellulites in the body EMS causes adaption‚ i.e. training of muscles fibers and can be used as a therapeutic tool. In medicine it is used for rehabilitation purposes‚ for instance in Physical therapy in the prevention of disuse muscle atrophy which can

valuable when additionally talking about weakness. A basic thought to recollect is that muscle compression is because of a particle called ATP (adenosine triphosphate). ATP must be available for muscles to contract. There are three frameworks of energy that create ATP: Phosphocreatine system‚ the glycolytic system‚ or the oxidative system. On the off chance that exhausted‚ it must be renewed if additional muscle withdrawal is to proceed. Since we are talking about ATP Pathways‚ I needed to additionally

types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct

A) by generating heat that helps maintain body temperature B) by moving materials through the body C) by pulling on bones to move the body D) A and B are correct. E) A‚ B and C are correct. 2) The primary function of muscle is A) conversion of chemical energy into mechanical energy. B) conversion of chemical energy into radiant energy. C) conversion

musculoskeletal system is made up of bones‚ joints‚ and muscles. This system gives the body form and support‚ and protects the body while allowing it to move. Basically‚ the muscles in this system perform three important body functions: the movement of body parts‚ maintenance of body parts‚ and production of body heat. These muscles all consist of a mass of protein fibers grouped together‚ and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were present at
