Skeletal muscle , also called voluntary muscle , in vertebrates , most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons , and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle , skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels.

Human muscle system

The muscular system consists of various types of muscle that each play a crucial role in the function of the body. Muscles allow a person to move, speak, and chew. They control heartbeat, breathing, and digestion. Other seemingly unrelated functions, including temperature regulation and vision, also rely on the muscular system. The muscular system contains more than muscles that work together to enable the full functioning of the body. Skeletal muscles are the only muscles that can be consciously controlled. They are attached to bones, and contracting the muscles causes movement of those bones.

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.

3 Types of Muscle Tissue: The Function of Skeletal, Cardiac, and Smooth Muscle

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. With very few exceptions, the arrangement of smooth muscle and cardiac muscle in humans is identical to the arrangement found in other vertebrate animals. This article is concerned with the skeletal muscles of the human body, with emphasis on muscle movements and the changes that have occurred in human skeletal musculature as a result of the long evolutionary process that involved the assumption of upright posture.

Nutrients that animals obtained are used for ATP production, which are fuels for the production of work by muscles, among other physiological processes in the animal bodies. Depending on what type of muscle tissues animals are using, they will use ATP differently to generate work. Overall, muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion. The body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle Figure 6. Because it can be controlled by thought, skeletal muscle is also called voluntary muscle. Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance.

3 different types: ○ Skeletal Smooth muscles and cardiac muscles are system. ○. Allows for conscious movement of skeletal muscles.


6.2 – Types of Muscles

Human skeletal muscle is composed of a heterogenous collection of muscle fiber types. In addition, muscle fibers can adapt to changing demands by changing size or fiber type composition. This plasticity serves as the physiologic basis for numerous physical therapy interventions designed to increase a patient's force development or endurance. Changes in fiber type composition also may be partially responsible for some of the impairments and disabilities seen in patients who are deconditioned because of prolonged inactivity, limb immobilization, or muscle denervation.

In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth.

Мидж горящими глазами смотрела ему вслед. - О нет, можешь, - прошептала. И, повернувшись к Большому Брату, нажатием клавиши вызвала видеоархив. Мидж это как-нибудь переживет, - сказал он себе, усаживаясь за свой стол и приступая к просмотру остальных отчетов. Он не собирается выдавать ключи от директорского кабинета всякий раз, когда Мидж придет в голову очередная блажь. Не успел он приняться за чтение отчета службы безопасности, как его мысли были прерваны шумом голосов из соседней комнаты.

Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств. На фотографии она была изображена наклонившейся над постелью, в одних трусиках. Как выяснилось, кто-то из криптографов сосканировал фотографию из порножурнала и приставил к телу головы модели голову Сьюзан. Получилось очень даже правдоподобно. К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного. Два часа спустя был издан ставший знаковым приказ: СОТРУДНИК КАРЛ ОСТИН УВОЛЕН ЗА НЕДОСТОЙНЫЙ ПОСТУПОК С этого дня никто больше не доставлял ей неприятностей; всем стало ясно, что Сьюзан Флетчер - любимица коммандера Стратмора.

К своему будущему. Шифровалка снова купалась в ярких огнях. Внизу фреон протекал сквозь дымящийся ТРАНСТЕКСТ, как обогащенная кислородом кровь.

Стратмор, несомненно, постарается проверить все лично и найти пароль из шестидесяти четырех знаков. Затем он его уничтожит, и Цифровая крепость навсегда исчезнет из Интернета. - Действуй своим маячком очень осторожно, - сказал Стратмор.  - Если Северная Дакота заподозрит, что мы его ищем, он начнет паниковать и исчезнет вместе с паролем, так что никакая штурмовая группа до него не доберется. - Все произойдет, как булавочный укол, - заверила его Сьюзан.

 - Мы же говорим не о реверсии какой-либо сложной функции, а о грубой силе. PGP, Lucifer, DSA - не важно. Алгоритм создает шифр, который кажется абсолютно стойким, а ТРАНСТЕКСТ перебирает все варианты, пока не находит ключ. Стратмор ответил ей тоном учителя, терпеливого и умеющего держать себя в руках: - Да, Сьюзан, ТРАНСТЕКСТ всегда найдет шифр, каким бы длинным он ни .

    Muscle classification: muscle tissue may be classified according to a morphological classification or a functional classification.
