Human skeleton , the internal skeleton that serves as a framework for the body.

The Functions of the Skeletal System

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.

Human skeleton

The skeletal system includes all of the bones and joints in the body. Each bone is a complex living organ that is made up of many cells, protein fibers, and minerals. The skeleton acts as a scaffold by providing support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachment points for muscles to allow movements at the joints. New blood cells are produced by the red bone marrow inside of our bones.

Bennett, M. University of Queensland, Brisbane, Australia. Last reviewed: December The supporting tissues of an animal that serve to protect the body, or parts of it, and play an important role in physiology. The skeletal system, often termed skeleton, encompasses the anatomical structures composed of bone and cartilage, or a combination of both, which provide a framework for the body and serve as attachment for muscles. Skeletons can be divided into two main types based on the relative position of the skeletal tissues.

The skeleton is subdivided into two divisions: the axial skeleton, the bones that form the longitudinal axis of the body, and the appendicular skeleton, the bones of the limbs and girdles. The adult skeleton is composed of bones and there are two basic types of osseous, or bone, tissue: compact bone and spongy bone, and are classified into four groups according to shape: long, short, flat, and irregular. To the naked eye , spongy bone has a spiky, open appearance, whereas compact bone appears to be very dense. The axial skeleton, which forms the longitudinal axis of the body, is divided into three parts: the skull, the vertebral column, and the bony thorax. The cranium encloses and protects the fragile brain tissue and is composed of eight large flat bones. Though not really part of the skull, the hyoid bone is closely related to the mandible and temporal bones.

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.

The skeletal system includes all of the bones, cartilages, and ligaments of the body that support and give shape to the body and body structures. For adults, there are bones in the skeleton. Younger individuals have higher numbers of bones because some bones fuse together during childhood and adolescence to form an adult bone.

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.

Сьюзан поняла, в чем дело: все это время Хейл вел себя тихо, подозрительно тихо, поскольку отлично знал, что нет такой диагностики, в которой использовалась бы цепная мутация, тем более такая, которая занимала ТРАНСТЕКСТ уже восемнадцать часов. Хейл не проронил ни слова. Казалось, вспыхнувшая на его глазах перепалка абсолютно его не касается. Очевидно, Стратмор вдруг задумался:. У Сьюзан имелся на это ответ.

В АНБ он получил кличку Джабба и приобрел репутацию полубога. Он бродил по коридорам шифровалки, тушил бесконечные виртуальные пожары и проклинал слабоумие нерадивых невежд.

The skeleton is the framework that provides structure to the rest of the body and facilitates movement. Page 5. When you look at the human skeleton the bones.
