    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

    Purpose: The purpose of this lab is to test what substances are necessary for muscle contraction. Hypothesis: Based off the frog muscle immersed separately in Solution A of ATP and distilled water solution‚ Solution B of ATP with KCl in distilled water and MgCl2 in distilled water and solution C of KCl and MgCl2 in distilled water‚ I hypothesize that solution B of ATP with KCl in distilled water and MgCl2 in distilled water will cause the muscle to contract. Introduction: This lab consisted of discovering

    Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked

    Skeletal Muscle Lab Introduction: Motor neurons and muscle fibers are the building blocks of motor units and where they intersect is called the neuromuscular junciton. The region where the flattened end of a motor neuron transmits neural impulses to a muscle is the motor end-plate. The end plate potentials depolarizes skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. The process of contraction of the muscle cell is called excitation-contraction

    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

    2017 Motor Unit Recruitment and Muscle Fatigue Lab Introduction Human skeletal muscles are made up of hundreds of cylindrically-shaped cells called myofibers‚ and they are bound together by connective tissue. These muscles are stimulated to contract by somatic motor nerves‚ or motor neurons‚ that carry signals in the form of nerve impulses from the brain or spinal cord‚ to the skeletal muscles. Although a motor neuron can innervate several fibers‚ each muscle fiber can only be innervated by one

    Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two
