Similarities And Differences Between Skeletal, Cardiac, And Smooth Muscle.

Improved Essays
Evaluate the anatomical and physiological similarities and differences between skeletal, cardiac, and smooth muscle.
Skeletal Muscles are attached to bones. Their functions include: produce skeletal movement, maintain posture and body position, support soft tissues, guard body entrances and exits, maintain body temperature, and store nutrients. They are striated muscles because of their appearances of having bands of actin and myosin that form the sarcomere which is located in the myofibrils. The skeletal muscle consists of it being enormous in size, multinucleate (containing hundreds of nuclei internal to the plasma membrane), and banded. These types of muscles are voluntary since we control them by nerve impulses by the brain transmitting

Smooth muscles are located within the hollow walls of organs such as the: oesophagus, stomach, bronchi, and blood vessel walls. They are stimulated by involuntary neurogenic impulses consisting of slow steady contractions that assist in controlling internal organs. For instance, during vasoconstriction blood vessels are constricted or as food passes through the esophagus (NIH, 2016).

Cardiac muscles are located within the walls of the heart. It is similar to the skeletal muscles being striated and similar to smooth muscles, as its contractions are not voluntarily conducted. They control the actions of the heart such as pumping the blood. However, it is specialized by the control of the autonomic nervous system. Cardiac muscles are very resistant to fatigue because of the vast amounts of myoglobin, mitochondria, and blood supply permitting consistent aerobic metabolism (NIH, 2016).

Distinguish fast, slow, and intermediate fibers. Provide an example of muscular activities for

These muscles are utilized in high intensity, but only for short activities that last a few minutes. For example, they are located: on parts of the back, abdominal wall, shoulders, certain areas of the gluteus, parts of the hamstring, and the aerobic heart rate zone of the 3rd. During weigh and training intermediate twitch muscles are used to perform 10 or more repetitions. A drop in glucose levels is seen during resistance training on a higher end of repetitions or a rise at the lower end. This depends on the ability of the body being able to generate and regulate glucagon, blood pressure, insulin, and heart rate (Integrative Healthcare,

    They are voluntary muscles which contain a lot of mitochondria. They are striated and have a long cylindrical shape. Skeletal muscle helps to maintain posture, stabilize joints and generate heat. Unlike skeletal muscles, smooth muscle tissues are smooth non-tubular (spindle-like) muscles that control slow involuntary movements. They are found in the walls of hollow organs and contain a single nucleus therefore they can function in digestive organs.…

    There are 3 different types of muscle: Visceral, Cardiac and Skeletal Muscle. • Visceral Muscle: Visceral muscles are found in the stomach, intestines and blood vessels. Visceral muscles make your organs contract and move substances through the organ. Visceral muscles are an involuntary muscle. It is also known as “smooth muscle” because of its appearance when it is viewed under a microscope.…

    Muscular system: Major functions The muscular system function is that it allows movement of body parts, and works with skeletal system to help us move. Major muscles types : There are many muscles in the muscular system. Some are skeletal, smooth, and cardiac muscle. The skeletal muscle, smooth muscle, and cardiac muscle can stretch and contract, but they complete different functions. The skeletal muscle is attached to your skeleton by strong, springy tendons or is directly connected to rough patches of bone.…

    The goal of endurance training is to improve aerobic power by conducting submaximal muscular contractions. Adversely, resistance training involves approximately maximal contractions occurring in short bouts. It also focuses on muscle hypertrophy, or the enlargement of muscle fibers (Knuiman, 2015). Due to this fact, skeletal muscle adapts to each type of exercise very differently. To understand how skeletal muscle fibers…

    As a kind of tension detection device for the muscle system, what protective role do GTOs play? GTOs play an important protective role for the muscle system since they sense changes in muscle tension. Because of this they can protect the muscle from excessive tension by causing the muscle to relax thus prevent injury and damage of muscles. Essay Questions 1. The sliding filament theory is how muscles are able to create force when having the thick (myosin) filaments slide past the thin (actin) filaments during muscle contraction overlapping in ratchet-like manner, this causes the sarcomere to contract, while staying at the same length.…

    Skeletal muscle cells have what is known as striations or stripe like appearance of the cell body. Skeletal muscle cells are multinucleated often because of their large size another distinction of muscle fibers. Skeletal muscle cells have a significant number of mitochondria this is a result of the large amount of energy that muscle contraction and movement use. Muscles build together much like cable or rope, muscles can be separated into bundles of fascicles and fascicles can be separated into bundles of muscles fibers and finally muscle fibers can be separated into bundles of myofibrils, which are another unique structure of skeletal muscle cells. This bundling allows muscles to have great strength in their…

    There are three type of muscle tissue found in the human body, smooth, cardiac and the skeletal muscle tissue. The smooth muscle tissue is found inside organs like the stomach, the blood vessels and the intestines. The smooth muscle tissue is an involuntary muscle, meaning it functions on its own without been controlled. The main function of the smooth muscle tissue is to make organs tightens to move substances in and out of the organs, and it is mainly controlled by the unconscious part of the human brain. The second type of muscle tissue is the cardiac muscle and it is found in the heart.…

    The somatic system is in charge of skeletal muscle contraction, which is normally voluntary. Whereas the autonomic nervous system is responsible for involuntary responses. For example, changes in the activities of glands or the digestive system. These systems often work together, like when you’re cold. Your brain signals to your autonomic nervous system to constrict surface blood vessels in your skin.…

    There are three types of muscle cells; skeletal, cardiac and smooth muscle tissue. The skeletal muscles are attached to bones and cause contraction which is how bones are able to move. Cardiac muscle also contracts to force blood out of the heart and around the body. Smooth muscle is found in a number of organs, including the reproductive organs, the lining of the bladder, the digestive tract and the respiratory tract. The smooth muscle in the lining of the bladder contracts to force the urine out of the bladder.…
