The human musculoskeletal system also known as the human locomotor system , and previously the activity system  is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton , muscles , cartilage ,  tendons , ligaments , joints , and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system's primary functions include supporting the body, allowing motion, and protecting vital organs.
Smooth Muscle Examples and Function
Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body. The human body contains three different kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart. In this article, we discuss the structure and function of cardiac muscle tissue. We also cover medical conditions that can affect cardiac muscle tissue and tips for keeping it healthy.
In the body, there are three types of muscle : skeletal striated , smooth, and cardiac. Skeletal muscle , attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system CNS controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated having transverse streaks and each acts independently of neighboring muscle fibers.
How Many Muscles Are in the Human Body?
In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions. Here are more details about the structure and function of each type of muscle tissue in the human muscular system. Skeletal muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system.
Muscle is one of the four primary tissue types of the body, and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle Figure 7. While the nervous system can influence the excitability of cardiac and smooth muscle to some degree, skeletal muscle completely depends on signaling from the nervous system to work properly. On the other hand, both cardiac muscle and smooth muscle can respond to other stimuli, such as hormones and local stimuli. Differences among the three muscle types include the microscopic organization of their contractile proteins, location in the body, and control mechanisms. The actin and myosin proteins are arranged very regularly in the cytoplasm of individual muscle cells referred to as fibers in both skeletal muscle and cardiac muscle, which creates a pattern, or stripes, called striations. Cardiac muscle, found within the heart, have fibers with one to two nuclei and are physically and electrically connected to each other so that the entire heart contracts as one unit.
The term smooth muscle refers to a muscle of the human body that is part of an involuntary muscle group. These muscles are extremely important to help the body perform a variety of crucial tasks, and can be found in many parts of the body. Keep reading to learn more about smooth muscle examples and how they function in the body. There are three types of muscles in the body: smooth muscles, cardiac muscles and skeletal muscles. Smooth muscles are unique in their largely involuntary response, and in their structure. Smooth muscles have a much stronger ability to contract than skeletal muscles, and are able to maintain contraction longer. Unlike skeletal muscles, which are located near bones and control bodily movement, smooth muscles are found in and around organs.

Human musculoskeletal system
Have you ever wondered how many muscles you have in your body? The answer to this question actually depends on the type of muscle. Other muscle tissue, such as smooth muscle, typically occurs on a cellular level, meaning that you can actually have billions of smooth muscle cells.
Human muscle system , the muscles of the human body that work the skeletal system , that are under voluntary control, and that are concerned with movement, posture, and balance. Broadly considered, human muscle—like the muscles of all vertebrates—is often divided into striated muscle or skeletal muscle , smooth muscle , and cardiac muscle. Smooth muscle is under involuntary control and is found in the walls of blood vessels and of structures such as the urinary bladder , the intestines , and the stomach. Cardiac muscle makes up the mass of the heart and is responsible for the rhythmic contractions of that vital pumping organ; it too is under involuntary control.
Заручившись поддержкой федеральных фондов и получив карт-бланш на все необходимые меры для решения проблемы, АНБ приступило к созданию невозможного - первой универсальной машины для вскрытия шифров. Вопреки широко распространенному мнению о том, что такой компьютер создать невозможно, АНБ осталось верным своему девизу: возможно все; на невозможное просто требуется больше времени.
