The Functions of the Skeletal System
Bone , or osseous tissue , is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body.
In the areas of the skeleton where bones move for example, the ribcage and joints , cartilage , a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:.
The most apparent functions of the skeletal system are the gross functions—those visible by observation. Simply by looking at a person, you can see how the bones support, facilitate movement, and protect the human body. Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilage of your skeletal system compose the scaffold that supports the rest of your body.
Without the skeletal system, you would be a limp mass of organs, muscle, and skin. Bones also facilitate movement by serving as points of attachment for your muscles. While some bones only serve as a support for the muscles, others also transmit the forces produced when your muscles contract. From a mechanical point of view, bones act as levers and joints serve as fulcrums [link]. Unless a muscle spans a joint and contracts, a bone is not going to move. For information on the interaction of the skeletal and muscular systems, that is, the musculoskeletal system, seek additional content.
Bones also protect internal organs from injury by covering or surrounding them. For example, your ribs protect your lungs and heart, the bones of your vertebral column spine protect your spinal cord, and the bones of your cranium skull protect your brain [link].
Orthopedist An orthopedist is a doctor who specializes in diagnosing and treating disorders and injuries related to the musculoskeletal system.
Some orthopedic problems can be treated with medications, exercises, braces, and other devices, but others may be best treated with surgery [link].
In recent years, orthopedists have even performed prenatal surgery to correct spina bifida, a congenital defect in which the neural canal in the spine of the fetus fails to close completely during embryologic development.
Orthopedists commonly treat bone and joint injuries but they also treat other bone conditions including curvature of the spine. Lateral curvatures scoliosis can be severe enough to slip under the shoulder blade scapula forcing it up as a hump. Spinal curvatures can also be excessive dorsoventrally kyphosis causing a hunch back and thoracic compression. These curvatures often appear in preteens as the result of poor posture, abnormal growth, or indeterminate causes.
Mostly, they are readily treated by orthopedists. As people age, accumulated spinal column injuries and diseases like osteoporosis can also lead to curvatures of the spine, hence the stooping you sometimes see in the elderly.
Some orthopedists sub-specialize in sports medicine, which addresses both simple injuries, such as a sprained ankle, and complex injuries, such as a torn rotator cuff in the shoulder. Treatment can range from exercise to surgery. On a metabolic level, bone tissue performs several critical functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium, and phosphorus.
These minerals, incorporated into bone tissue, can be released back into the bloodstream to maintain levels needed to support physiological processes. Calcium ions, for example, are essential for muscle contractions and controlling the flow of other ions involved in the transmission of nerve impulses.
Bone also serves as a site for fat storage and blood cell production. The softer connective tissue that fills the interior of most bone is referred to as bone marrow [link]. There are two types of bone marrow: yellow marrow and red marrow. Yellow marrow contains adipose tissue; the triglycerides stored in the adipocytes of the tissue can serve as a source of energy.
Red marrow is where hematopoiesis —the production of blood cells—takes place. Red blood cells, white blood cells, and platelets are all produced in the red marrow.
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system. Which function of the skeletal system would be especially important if you were in a car accident? The skeletal system is composed of bone and cartilage and has many functions. Choose three of these functions and discuss what features of the skeletal system allow it to accomplish these functions.
It supports the body. The rigid, yet flexible skeleton acts as a framework to support the other organs of the body. It facilitates movement. The movable joints allow the skeleton to change shape and positions; that is, move.
It protects internal organs. Parts of the skeleton enclose or partly enclose various organs of the body including our brain, ears, heart, and lungs. Any trauma to these organs has to be mediated through the skeletal system. It produces blood cells. The central cavity of long bones is filled with marrow. The red marrow is responsible for forming red and white blood cells.
It stores and releases minerals and fat. The mineral component of bone, in addition to providing hardness to bone, provides a mineral reservoir that can be tapped as needed. Additionally, the yellow marrow, which is found in the central cavity of long bones along with red marrow, serves as a storage site for fat.

Human musculoskeletal system
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. 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 skeletal system gives the body its basic framework, providing structure, protection, and movement. The bones in the body also produce blood cells, store important minerals, and release hormones necessary for bodily functions. Unlike other living organs, bones are firm and strong, but they have their own blood, lymphatic vessels, and nerves. Red bone marrow forms most of the blood cells in the body and helps destroy old blood cells. Another type of marrow, yellow bone marrow , resides in the central cavities of long bones. It is mostly made up of fat. However, if the body suffers large amounts of blood loss, it can convert yellow marrow to red in order to make more red blood cells.
Bone , or osseous tissue , is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body. In the areas of the skeleton where bones move for example, the ribcage and joints , cartilage , a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:.

Bones: All you need to know
The human Skeletal System is the bony framework of the body. The skeleton parts are described in two parts axial and appendicular. The appendicular skeleton attached to the axial Skeleton. The axial skeleton consists of the skull, vertebral column, sternum, and ribs. The skull described in two parts, the cranium which contains the brain, and the face.

It consists of bones and connective tissue, including cartilage, tendons, and ligaments. The skeletal system is a network of many different parts that work together to help you move. There are bones in an adult human skeleton. Each bone has three main layers:.
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.
Все прочитали: - Разница в весе незначительна… разделяются вследствие газовой диффузии… 10,032498X10134 в сравнении с 1939484X1023. - Ну вот, наконец-то! - вскрикнул Джабба. - Это и есть их вес. - Тридцать секунд.
Сьюзан сумела лишь невнятно прошептать: - ТРАНС… Бринкерхофф кивнул. - Забудьте об. Поехали. Свет от фары пробежал по цементным стенам.
Росио пожала плечами. - Сегодня днем. Примерно через час после того, как его получила. Беккер посмотрел на часы - 11.
ВСЯ ХИТРОСТЬ В МЕНЯЮЩЕЙСЯ ПОСЛЕДОВАТЕЛЬНОСТИ. В это трудно было поверить, но она видела эти строки своими глазами. Электронная почта от Энсея Танкадо, адресованная Грегу Хейлу. Они работали .
Убийца целился, высунувшись из окна. Беккер вильнул в сторону, и тут же боковое зеркало превратилось в осколки. Он почувствовал, как этот удар передался на руль, и плотнее прижался к мотоциклу. Боже всевышний. Похоже, мне не уйти.
Теперь он уже бежал по узкому проходу. Шаги все приближались. Беккер оказался на прямом отрезке, когда вдруг улочка начала подниматься вверх, становясь все круче и круче.
