Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output

Anatomy of Muscle Cells There are three types of muscle tissue in the human body. These muscle tissues are skeletal muscles‚ smooth muscles and cardiac muscles. Each of these muscle tissues has it very own anatomical makeup‚ which vary from muscle to muscle. The muscle cells in a muscle are referred to as muscle fibers‚ these fibers are skeletal muscle fibers‚ smooth muscle fibers and cardiac muscle fibers. The anatomy of a skeletal muscle fiber is formed during embryonic development

Chapter 10 Muscle The muscular system helps in providing the movement for bones and in doing so allows the body to make complex movements. Muscle is one of the four types of primary tissue. The three kind of muscle tissue that make up the human body are: skeletal muscle‚ smooth muscle‚ and cardiac muscle. Skeletal muscle is voluntary and are usually found attached to bones where they help to produce movement of the skeleton. Smooth muscle is involuntary and are usually found in the walls of the

Your muscles are always moving. It is impossible to sit still. Your heart is always pumping‚ and your muscles make you breath and hold you upright. If your muscles all relaxed at the same time‚ you would collapse. You would not be able to survive without your muscular system. There are three types of muscle in your body: smooth muscle‚ cardiac muscle‚ and skeletal muscle. Smooth muscle is located in the digestive tract and in the walls of blood vessels. It moves food through the digestive system

muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating a length-tension
