The skeleton has five main functions: Movement – the skeleton allows movement of the body as a whole and its individual parts. The bones act as levers and also form joints that allow muscles to...

- Structure. Like the steel framework of a building, the functions of the skeleton and the bones is to provide rigidity, which gives the body shape and supports the weight of the muscles and organs.
- Movement. There are three major systems involved in the mechanics of movement: Nervous system. Muscular system. Skeletal system. The nervous system sends the electrical impulses that activate the muscles, the skeletal system provides the levers and anchors for the muscles to pull against.
- Protection. Arguably the most important of the 5 functions of the skeletal system is protection. The most obvious example of the functions of the skeleton's protective properties is the human skull.
- Blood Cell Production. Red and white blood cells are made in the red marrow of bones. At birth and in early childhood, all bone marrow is red. As the person ages, about half of the body’s marrow turns to yellow marrow – which is composed of fat cells.

In humans, the skeletal system consists of bones, joints and associated cartilages. An adult human has 206 bones in their body and variety of different joints. Image shows a human skeleton with the major bones labeled. The human skeleton can be divided into two components: the axial skeleton and the appendicular skeleton. The axial skeleton is form...
Support
The first and most apparent function of the skeletal system is to provide a framework for the body. The presence of a firm bony skeleton allows the organism to have a distinctive shape adapted towards a particular lifestyle. For instance, in a fast-moving animal like the cheetah, the skeleton contains long, thin limb bones and an extremely flexible spine. The structure of the skeleton also allows it to absorb the impact of running at high speeds. The bones of birds are hollow, light and creat...
Integration with the Muscular System
The skeletal system also provides an important form of attachments to the muscular system. Bones and exoskeletons are hard and do not bend or move when muscles are flexed. This means that the contraction of muscle cells will lead to the shortening of muscles, while the bone retains its shape.This basic structure allows muscles to move different parts of the body, using forces generated while pulling on the skeletal system.
Protection
The next obvious function of the skeletal system is the role it plays protecting the fragile internal organs. In humans, this is seen in the skull, which surrounds the brain completely.It is also exhibited by the ribcage, which surrounds the lungs and heart but still allows for expansion. Even invertebrates like snails and prawns often have hard exoskeletons to protect themselves from predators. The rigid endoskeletonallows the body to rise up above the ground or stand upright, and bears the...
The anatomy of the skeletal system is complex, and it includes hundreds of bones in the human body. The anatomy of the system varies widely between organisms, as evolution has selected for various adaptations in certain species which change the structure and function of their bones.
In general, the skeletal system is structured to provide support against gravity and protect an animal’s internal organs. While this article mainly discusses the human skeletal system, most animals have some sort of skeleton. Some animals, like sponges, can have an extremely simplified skeleton made of calcium deposits within the animal.Others, lik...
Diseases of the skeletal system could be confined to one section of the skeleton such as changes to the curvature of the spine, or they could be a genetic disorder affecting all bones and joints such as arthritis or osteoporosis. The spine in healthy individuals is S-shaped, with a convex curvature for the thoracic region and the concave tilt in th...
Three bones in the inner ear, called malleus, incus and stapes, are the smallest bonesin the human body. The thigh bone, or femur, is the largest bone.The hyoid bone situated behind the lower jaw is also called a ‘floating’ bonebecause it is not part of any joint, and is not directly attached to any other bone.The position of the hyoid bone makes it extremely resistant to fractures. However, autopsies that reveal a broken hyoidbone indicate death from strangulation.Newborn babies have about 300 bones. Many of these bones fuse togetherto form the 206 bones of the adult.- Gabe Buckley
Jan 10, 2024 · The skeletal system is your body’s support structure. It gives your body its shape, allows movement, makes blood cells, provides protection for your organs and stores minerals. The skeletal system is also called the musculoskeletal system.
The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body: supports the body; facilitates movement; protects internal organs; produces blood cells; stores and releases minerals and fat
