types of muscle tissues : skeletal, cardiac, smooth. Each of these different tissues has the ability

There are three main types of muscle tissue in the body: Skeletal muscle, smooth muscle and cardiac muscle. Firstly, skeletal muscle has a stripped appearance when it is examined under a microscope so it is sometimes known as striated/stripped muscle. Skeletal muscle is voluntary and this means that it is under conscious control. Secondly, there is smooth muscle which is an involuntary muscle that operates without any conscious control. This muscle is controlled by the nervous system. Smooth muscle can be found in the blood vessels and the walls of the digestive system and it helps to control digestion and blood pressure. Lastly, there is cardiac muscle which is located in in the wall of the heart. Cardiac muscle is involuntary and this means that it is not under conscious control. This is made up of a specialised type of tissue which is striated and it has its own blood supply. The contractions aid the pumping of blood through the blood vessels

These muscle tissue cells specialised to contract and move parts of the body. It is also capable of responding to stimuli. There are three types of muscle in the body such as: skeletal, cardiac and smooth. Each muscle is created of muscle fibers that are capable of contracting and returning back to original state-relaxation. Contraction causes movement of the skeleton, soft tissue, blood or specific material. Skeletal muscle is attached to the bones of the skeleton. Some facial muscles are attached to the skin. They have direct control over them through nervous impulses from our brain sending messages to the muscle. Contractions can vary to produce fast, powerful movements. These muscles also have the ability to stretch and contract to return to original shape. Cardiac muscles are found in the chambers of the heart such as the atria and ventricles. It is under the control of the automatic nervous system; however, even without nervous input contractions can occur. It is completely different to all the other muscles. Smooth muscles are also known as involuntary due to our inability to control its movement. This muscle is usually found in the walls of hollow organs

Introduction: According to the “Human Physiology Laboratory Manual “,BIOL 282 ,page 31 , the reason of performing this experiment is to learn how the muscle contraction occurs based on the molecular level and what kind of factors are involved .As a matter of fact, skeletal muscles contain a lot of nuclei because of the cell fusion while being developed and are made of cylindrical cells that have myofibrils. The myofibrils contain sarcomeres and the

10. two of the main types of muscle tissue correspond with muscles that are involuntary, they are cardiac muscle, which includes the heart. Smooth muscle, which is also involuntary, and includes the stomach, intestines, uterus, urethra, bladder, and blood vessels. The Skeletal muscles are voluntary, they’re attached to the bone and are used to affect skeletal movement.

Chapter 13 talks about the muscular system and the way that it is works together with the skeletal system and other systems in our body. It also explains the ways our muscles contract and move and what processes are going on in within our muscles when we work each one of them. The chapter also talks about disorders that can happen within our muscles and the way they affect our life. What I found most surprising in the chapter was reading the box that talked about botox ad wrinkles. It was shocking to read that the toxin used for botox is one of the most lethal substances and yet people are voluntarily putting it in their body. Another thing that surprised me to know was that the same substance had also been approved to treat migraine headaches.

There are three types of muscle tissue: skeletal, cardiac and smooth muscle. Skeletal muscle is attached to bones and helps with movement. Cardiac muscle is found the heart helping the heart to contract and pump blood through an organism. Smooth muscle lines the walls of organs in the digestive and urogenital tracts.

Individual muscles are made up of individual muscle fibers and these fibers can be further organized into a motor unit grouped within each muscle. A motor unit is simply a bundle of grouped muscle fibers. When you want to move the brain instantaneously sends a signal or impulse through the spinal cord that reaches the motor unit. Muscle fibers are cells like the basic building block of the muscle. There are a few different types of muscle fibers, each are designed for a specific type of muscle activity. Some muscle fibers are good for endurance exercises, other work best for the short bursts. Each muscle fiber is a single cell. Each cell consists of a structure.

In Anatomy and Physiology, one of the topics this class recently covered was the muscle system. In the video, “How Your Muscular System Works” published in 2017 by Emma Bryce said a brief explanation of how the muscular system works. In the video, Bryce stated, “Each time you take a step, two hundred muscles work in unison to lift your foot, propel it forward, and set it down.” Indeed, each muscle is responsible to do a specific movement. The muscle system is a very important system because this is where the three types of muscles come from. For example, in the video, it talked about the skeletal muscle, cardiac muscle, and the smooth muscle. The skeletal muscle is involuntary muscle and voluntary muscles. In addition, the cardiac muscle and the smooth muscle are only involuntary muscles. The cardiac muscle is only found in the heart. The smooth

Smooth muscles are found in the skin, internal organs, reproductive system, major blood vessels, and excretory system. Skeletal muscles are composed of long fibers surrounded by a membranous sheath, the sarcolemma. Since the Skeletal muscles are under control by whom ever they belong to are called voluntary muscles. This muscle is attached to two or more bones which are then attached to the skeleton by tendons. For example, head and neck muscles; contraction of these muscles produces facial expressions and head movements. They are also responsible for speech and swallowing. Skeletal muscles are the main muscles which move your body. Muscles nearly always work in coordinated groups; contraction of one muscle is accompanied by relaxation of another, while other muscles stabilize nearby joints. Then the last of the muscle types is the Cardiac Muscle or the involuntary muscles. Cardiac muscles are not under conscious control they do not react by a persons decision or movement. and are connected to the nervous system which are stimulated by autonomic impulses. Cardiac muscles are found in your internal organs like the heart or the intestine. For example; they include muscles that propel food through the intestine and those that control sweating and blood pressure.

Skeletal Muscles: Most of the human body weight. They are called skeletal muscles because they are almost always found attached to the skeleton and produce movements in different parts of the skeleton. There are more than 600 skeletal muscles. These signals and movements are nearly involuntary,

While some guys are born with a naturally muscular body, the majority of us have to work very hard for it. One of the greatest challenges in building muscle is learning the right techniques and strategies to maximize your muscle growth. For most beginners the bad habits they learn without proper guidance will have them reach their muscle gaining plateau very quickly. For some this is enough to give up; thinking that they just can't build muscle.

The Muscular System is the body system that moves bones at joints and pushes substances such as blood, food, and fluids throughout the body.

1. Why does the force begin to decrease with time? Note that a decrease in force indicates muscle fatigue.
