Bones are an important part of the musculoskeletal system. This article, the first in a two-part series on the skeletal system, reviews the anatomy and physiology of bone. The skeletal system is formed of bones and cartilage, which are connected by ligaments to form a framework for the remainder of the body tissues.

Underneath our skin are lots of things that make up our body. Two of these are bones and muscles. Bones shape our body and help us to stand up straight.

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. Smooth muscle and cardiac muscle and the physiology of muscle contraction are treated at great length in the article muscle.

The human musculoskeletal system also known as the human locomotor system , and previously the activity system [1] 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 , [2] 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. This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide stability to the body.

The musculoskeletal system is an organ system that enables an organism to move, support itself, and maintain stability during locomotion. The musculoskeletal system also known as the locomotor system is an organ system that gives animals including humans the ability to move, using the muscular and skeletal systems. It provides form, support, stability, and movement to the body. Its primary functions include supporting the body, allowing motion, and protecting vital organs. The bones of the skeletal system provide stability to the body analogous to a reinforcement bar in concrete construction. Muscles keep bones in place and also play a role in their movement. To allow motion, different bones are connected by articulating joints, and cartilage prevents the bone ends from rubbing directly onto each other.

Acromegaly is caused by an excess of growth hormone in adults, which causes the overgrowth of bones in the face, hands, feet and internal organs. Exercise can prevent age-related changes to muscles, bones and joints and can reverse these changes too. A person with amyloidosis produces aggregates of insoluble protein that cannot be eliminated from the body. Ankle sprain is a common sports injuries caused by overstretching and tearing the supporting ligaments.

The human skeleton has a number of functions, such as protection and supporting weight. Different types of bones have differing shapes related to their particular function. There are flat bones in the skull occipital, parietal, frontal, nasal, lacrimal, and vomer , the thoracic cage sternum and ribs , and the pelvis ilium, ischium, and pubis. The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.

У всех такие… - На ней майка с британским флагом и серьга в форме черепа в одном ухе. По выражению лица панка Беккер понял, что тот знает, о ком идет речь. Мелькнул лучик надежды. Но уже через минуту парень скривился в гримасе. Он с силой стукнул бутылкой по столу и вцепился в рубашку Беккера.

Какого черта! - подумал.  - Что я делаю здесь в пять вечера в субботу. - Чед? - В дверях его кабинета возникла Мидж Милкен, эксперт внутренней безопасности Фонтейна. В свои шестьдесят она была немного тяжеловатой, но все еще весьма привлекательной женщиной, чем не переставала изумлять Бринкерхоффа. Кокетка до мозга костей, трижды разведенная, Мидж двигалась по шестикомнатным директорским апартаментам с вызывающей самоуверенностью.

Она стояла у второй входной двери, что была в некотором отдалении, прижимая сумку к груди. Она казалось напуганной еще сильнее, чем раньше. - Мистер, - сказала она дрожащим голосом, - я не говорила вам, как меня зовут. Откуда вы узнали. ГЛАВА 74 Шестидесятитрехлетний директор Лиланд Фонтейн был настоящий человек-гора с короткой военной стрижкой и жесткими манерами. Когда он бывал раздражен, а это было почти всегда, его черные глаза горели как угли.

Повисла тягостная тишина. Когда Мидж заговорила, ее голос был мрачным: - Стратмор мог обойти фильтры. Джабба снова вздохнул. - Это была шутка, Мидж.  - Но он знал, что сказанного не вернешь. ГЛАВА 62 Коммандер и Сьюзан стояли у закрытого люка и обсуждали, что делать .

How does the skeleton move? Muscles throughout the human body are attached to bones. Nerves around a muscle can signal the muscle to move.
