3 Muscle Types

Words: 236

Pages: 1

There are three types of muscle which are cardiac muscle, smooth muscle, and skeletal muscle. Skeletal muscle is the only type of muscle that is voluntary so the muscle contractions can be controlled. The structure of the Skeletal muscle can be seen in Figure 6. Skeletal muscle is made up of bundles of long and thin cells that are called muscle fibers. Each muscle fiber contains hundreds of organelles called myofibrils . The muscle fibers are surrounded by a delicate tissue called the Endomysium. The bundles of muscle fibers called Fascicles are surrounded by connective tissue fibers of the Perimysium. Finally, the muscle is surrounded by a connective tissue sheath called the Epimysium and it is connected to the Tendon which connects it to

Essay on Electromyogram: Muscle Fibers

Experiment 1: (i) See Figure 1 for trace. Figure 1 is measuring the activity (force and time of contraction) of the entire muscle, which consists of several types of muscle fibers (Type I or slow twitch, Type IIa or intermediate fast twitch, and Type IIb or fast, fatigable/anaerobic) whereas a concentric needle electrode only detects and records the activity of one type of muscle fiber. A typical triphasic waveform is observed, in contrast to the monophasic shape of the intracellular action potential…

Nervous vs. Muscle The locations of both nervous and muscle tissue are much the same in that, there are both located throughout the human body. There are 3 different types of muscle tissues based on their locations. Skeletal muscle is found attached to bones and is involved in voluntary contractions of the muscles. Cardiac muscle is situated in the heart and smooth muscle is stationed in the walls of hollow organs such as the large and small intestines. Both Cardiac and Smooth muscle are involved…
