Arthritis — As we age, our joint tissues become less resilient to wear and tear and start to degenerate manifesting as swelling, pain, and oftentimes, loss of mobility of joints.

Musculoskeletal disorders are among the most important occupational health problems in both developed and developing countries. These disorders affect the quality of life of most people during their lifetime. The annual cost of musculoskeletal disorders is great. In the Nordic countries, for example, it is estimated to vary from 2.

Muscle Disorders

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.

Its medical name is kyphosis, and it is defined as excessive curvature of the spinal column in the thoracic region. The curvature generally results from fractures of thoracic vertebrae. As the inset drawings suggest, these fractures may occur due to a significant decrease in bone mass, which is called osteoporosis. Osteoporosis is one of the most prevalent disorders of the skeletal system. A number of disorders affect the skeletal system, including bone fractures and bone cancers. However, the two most common disorders of the skeletal system are osteoporosis and osteoarthritis. At least ten million people in the United States have osteoporosis, and more than 8 million of them are women.

From about age 30, the density of bones begins to diminish in men and women. This loss of bone density accelerates in women after menopause. As a result, bones become more fragile and are more likely to break see Osteoporosis , especially in old age. As people age, their joints are affected by changes in cartilage and in connective tissue. The cartilage inside a joint becomes thinner, and components of the cartilage the proteoglycans—substances that help provide the cartilage's resilience become altered, which may make the joint less resilient and more susceptible to damage. Thus, in some people, the surfaces of the joint do not slide as well over each other as they used to.

The musculoskeletal system provides form, stability, and movement to the human body. It consists of the body's bones which make up the skeleton , muscles , tendons , ligaments , joints , cartilage, and other connective tissue. The term "connective tissue" is used to describe the tissue that supports and binds tissues and organs together. Its chief components are collagen and elastic fibers, which are composed of different proteins. The musculoskeletal system undergoes many changes as people age see Effects of Aging on the Musculoskeletal System.


Tetany: It is caused due to low blood calcium and is characterized by rapid or wild spasms.


Musculoskeletal system diseases

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.

While most people associate muscles with strength, they do more than assist in lifting heavy objects. The muscles in the body not only support movement — controlling walking, talking, sitting, standing, eating and other daily functions that people consciously perform — but also help to maintain posture and circulate blood and other substances throughout the body, among other functions.

The Musculoskeletal System in Animals

The musculoskeletal system consists of bones, cartilage, muscles, ligaments, and tendons. Primary functions of the musculoskeletal system include support of the body, provision of motion, and protection of vital organs. The skeletal system serves as the main storage system for calcium and phosphorus and contains critical components of the hematopoietic system. Many other body systems, including the nervous, vascular, and integumentary systems, are interrelated, and disorders of any one of these systems may also affect the musculoskeletal system and complicate diagnosis. Diseases of the musculoskeletal system most often cause lameness.

В шифровалке никогда еще не было так тихо, здесь всегда слышался гул генераторов. Теперь все умолкло, так что можно было различить облегченный вздох раненого чудовища - ТРАНСТЕКСТА, постепенно стихающее шипение и посвистывание, сопутствующие медленному охлаждению. Сьюзан закрыла глаза и начала молиться за Дэвида. Ее молитва была проста: она просила Бога защитить любимого человека.


Arthritis: Inflammation of one or more joints.


Osteoporosis

Согласился подежурить в этот уик-энд. Глаза Стратмора сузились. - Странно. Я вчера говорил с. Велел ему сегодня не приходить. Он ничего не сказал о том, что поменялся с тобой дежурством.

 - Женщина положила трубку. Вторая попытка также ни к чему не привела. Беккер заглянул в телефонный справочник. Оставался последний номер. Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина.

Мидж повернулась к нему на своем стуле. - Это не смешно, Чед. Заместитель директора только что солгал директорской канцелярии.
