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 stimulates

There are many different things that contribute to the elasticity of muscles‚ but the focus of Aboodarda and colleagues is specifically on myofascia‚ the irregular dense connective tissue that connects and encompasses every muscle and organ in the body‚ as it is the component that is thought to have responsibility for the elasticity of muscle tissues. As a response to injury‚ among other factors‚ myofascia may bond to abutting structures and contract‚ which may cause adhesions. These adhesions may

There are many different muscles groups that are used during exercise. Some of the main muscle groups are hamstrings‚ quads‚ glutes‚ and pectoral muscles. There are different muscle within each muscle group. In the hamstring muscles‚ there are three main muscles: semitendinosus‚ semimembranosus‚ and biceps femoris. In the quad muscles there are four main muscles: rectus femoris‚ vastus lateralis‚ vastus intermedius‚ and vastus medialis. There are three main muscles in the glutes: gluteus maximus

Comparison of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins

The musculo skeletal system is an organ system that gives humans the ability to move‚ it provides stability‚ protection‚ movement and support to the body . It is also made up of bones‚ tendons‚ ligaments‚ cartilage‚ joints and other connective tissue that binds tissues and organs together. The musculo skeletals job is to The skeletal system acts like a framework to support vital organs by keeping them place when doing vigourous sports‚ for example the vertebrae acts like a pillar and holds the

Fiber Optic Connector Assembly The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and
