In comparison to this smooth muscle does not have such a direct impact on Wilkinson’s game. However it is important for his success. His lungs are made of smooth muscle, these enable him to oxygenate his blood for the muscles. The stronger the lungs the better his cardiovascular performance will be in his game. Also smooth muscle is key for digestion, Wilkinson needs to be physically big and have an edge on his opponents. His smooth muscle in his digestive system is key for the absorption of protein which is a key nutrient for muscle growth. This clearly shows that smooth muscle helps Wilkinson gain muscle and enables him to have a physical edge in his game of rugby.…

Muscular System: The muscular systems is responsible for maintaining posture, circulating blood, and movement. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The stomach secretes acid and enzymes that digest food. The muscular system also has another variant which is skeletal muscle. The skeletal muscles are attached to bones and move various parts of the body. The biceps, pectoralis major, triceps, nasalis, and deltoid are five major organs in the muscular system. The biceps main job is to control the movement of the elbow and shoulder. The pectoralis major make up most of the chest bulk. The triceps help extend and retract the forearm. The nasalis compress nasal cartilage. The deltoid is responsible…
Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells, smooth muscle cells are not striated, and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system, and do not contract voluntarily. Smooth muscle contracts slowly, and does not exhibit the characteristic “twitch” seen in skeletal muscle. In addition, smooth muscle is not prone to muscle fatigue, making it an ideal component of sphincter muscles. Smooth muscle is found in the gastrointestinal tract of many animals, and is responsible for peristaltic movements. Smooth muscle is also present in the walls of arteries and arterioles, where it helps to regulate blood pressure and flow.…
4) Smooth Muscle – organ walls and blood vessel walls, involuntary, spindle-shaped cells for pushing things through organs. 5) Skeletal Muscle – large body muscles, voluntary, striated muscle packed in bundles and attached to bones for movement. 6) Cardiac Muscle – heart wall, involuntary, striated muscle with intercalated discs connecting cells for synchronized contractions during heart beat.…

_____25. In which of the following structures would one most likely find smooth muscle? a) biceps muscle b) heart c) digestive tract d) quadriceps muscle e) gluteus maximus muscle…
Smooth muscle- are involuntary muscles found in the walls of hollow organs like the stomach, intestines or bladder. Smooth Muscles have many functions in the body, but one of the functions of smooth muscles in the bladder contracts to push urine out of the body.…
Human skeletal muscle consists of hundreds of individual cylindrically shaped cells (called fibers or myofibers) bound together by connective tissue. In the body, these muscles are stimulated to contract by somatic motor nerves that carry signals in the form of nerve impulses from the brain or spinal cord…

Stabilizing body positions * Regulation organ volumes * Bands of smooth muscle called sphincters Functions of Muscle Tissue * Movement of substances within the body * Blood, lymph, urine, air, flood and fluids, sperm * Production of heat * Involuntary contractions of skeletal muscle (shivering) * Excitability * Respond to chemicals released from nerve cells Properties of Muscle Tissue * Conductivity * Ability to propagate electrical signals over membrane * Contractility * Ability to shorten and generate force * Extensibility * Ability to be stretched without damaging the tissue * Elasticity…
Smooth muscles can be found throughout your body from in your digestive system, in blood vessels and in your eyes. These muscles operate on their own and are not controlled by the brain. These muscles move food through your digestive system and they also regulate the blood flow in the body. These muscles are smooth in appearance.…
The muscular system is what is responsible for the way that we move. Without the muscular system, we wouldn't be able to participate in the normal activities that we do today. There are 700 known/named muscles that are attached to the human skeleton. There are three different types of muscle that can be found in the human body. The Visceral muscle which can be found inside organs such as the stomach. This type of muscle is controlled by the unconcious part of the brain. This muscle is also known as the involuntary muscle. Cardiac Muscle is the second type of muscle found in the human body, and you guessed it, you can find cardiac muscle in the heart! Cardiac muscles are responsible for pumping blood throughought the human body. And these muscles…
