Task 1. Muscular system carries out movement of the body, maintaining body balance, as well as breathing movements, transporting food and blood within the body. In the tissues of the muscular system, chemical energy is converted into mechanical and thermal energy. The muscular system is a collection of contractile muscle fibers, united in bundles, which form special organs - muscles or are independently part of the internal organs.
There are three types of muscles in humans: 1. Skeletal muscles(they are also striated, or arbitrary). Attached to bones. They consist of very long fibers, length from 1 to 10 cm, shape - cylindrical. Their transverse striations are due to the presence of alternating disks that are birefringent through transmitted light - anisotropic, darker, and one-refracting light - isotropic, lighter.
2. Smooth muscle(involuntary). They are found in the walls of internal organs and blood vessels. They are characterized by length: 0.02 -0.2 mm, shape: fusiform, one oval nucleus in the center, no striations. These muscles are involved in transporting the contents of hollow organs, such as food, through the intestines, regulating blood pressure, constricting and dilating the pupil, and other involuntary movements within the body. Smooth muscles contract under the influence of the autonomic nervous system.
3. Heart muscle. It exists only in the heart. This muscle contracts tirelessly throughout life, ensuring the movement of blood through the vessels and the delivery of vital substances to the tissues. The cardiac muscle contracts spontaneously, and the autonomic nervous system only regulates its operation.
There are about 500 skeletal muscles in the human body.
Functions of the muscular system (muscles)
Motor (muscle tissue participates in heartbeat; peristalsis of internal organs; skeletal muscle tissue moves joints);
Maintaining the body in space (skeletal muscles have muscle tone, which ensures the vertical position of the body);
Energy (conversion of chemical energy into mechanical and thermal energy. Due to the presence/absence of heat, muscles are able to relax/tighten and involuntarily contract quickly in cold weather - trembling);
Protective (for example, protecting the abdominal cavity with the abdominal press);
Formative (muscle development to some extent determines the shape of the body);
It is a kind of sensory organ due to the presence of special receptors
Participates in the formation of the walls of body cavities (oral, abdominal)
Helps improve blood and lymph circulation
Is a depot of salts, water and oxygen
Meaning
The muscular system consists of various organs and muscle tissue. Each of these organs and muscle tissues has a specific task in the functioning of the body.
Hypodynamia - insufficient muscle activity. The prevalence of physical inactivity is increasing due to urbanization, automation and mechanization of labor, increasing the role of means of communication. Due to the lack of necessary physical activity, people spend more and more time in a sitting or lying position. Without work, muscles weaken and gradually atrophy. Strength and endurance decrease, neuro-reflex connections are disrupted, leading to disruption of the nervous system (development vegetative-vascular dystonia, depression, myofascial syndromes), metabolic disorders. Over time, due to physical inactivity, changes in the musculoskeletal system increase: bone mass progressively decreases (development osteoporosis), the function of peripheral joints suffers ( osteoarthritis) and spine ( osteochondrosis) . Long-term physical inactivity leads to cardiovascular diseases ( cardiac ischemia, arterial hypertension), breathing disorders ( chronic obstructive pulmonary disease) and digestion (intestinal dysfunction).
The chain of endocrine disorders due to physical inactivity is manifested by metabolic syndrome (obesity, insulin resistance and increased risk of atherosclerosis).
All these changes ultimately lead to a decrease in life expectancy.
