Split-tensile Strength The splitting tests are well known indirect tests‚ were conducted as per IS 5816:1999 and used in the concrete tensile strength determination sometimes called split tensile strength of concrete. The size of cylinder is 300mm length with 150mm diameter or 200mm with 100mm diameter. The specimen were kept in water for curing for 3 days‚ 7 days and 21 days and on test day remove and allow the surface to dry. The test is performed out by placing a cylindrical specimen horizontally

Lab 3 – Skeletal Muscle Physiology Introduction Skeletal muscles are composed of hundreds to thousands of individual cells‚ each doing their share of work in the production of force. As their name suggests‚ skeletal muscles move the skeleton. Skeletal muscles are remarkable machines; while allowing us the manual dexterity to create magnificent works of art‚ they are also capable of generating the brute force needed to lift a 100-lb. sack of concrete. When a skeletal muscle from an experimental

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

Laboratory – Muscle Physiology A. MUSCLE TONUS Observations‚ Report and Conclusion: A. Define muscle tonus and give its importance * Muscle tonus refers to a state of slight muscular contraction maintained by synchronous impulses of low frequency‚ discharged by the spinal motor neurons. * Reflex in nature. * Muscle tonus is a small amount of tension in the muscle due to weak‚ involuntary contractions of its motor units. Muscle tonus is important in a sense that it governs the

Premium Muscle Acetylcholine Nerve
The muscle physiology of skeletal muscle was observed by using electrical‚ physical‚ and neural stimulations of an isolated gastrocnemius muscle from Rana pipiens. The gastrocnemius receives signals from the action potentials of the sciatic nerve. The muscle contraction is caused by the binding of a neurotransmitter once the action potential reaches the neuromuscular junction. Stimulation of the muscle and the sciatic nerve allows for recording and measuring of these properties. We observed twitch

Wednesday‚ 13 February‚ 2013 iWorx Lab Report 01 - Agonist/Antagonist Muscles In this first iWorx lab‚ students studied and observed agonist and antagonist muscles. Agonist‚ which are also known as prime movers‚ are the main muscles that are responsible for bringing two bones closer. The antagonist‚ is the muscle that relaxes as the agonist contracts. The lab was a physical example to show students which muscle was which. It also allowed students to see how the muscle activity was recorded by an electromyogram
