Skeletal System Powerpoint

Human skeleton, the internal bones that serve as the body’s framework. This system contains many bones and cartilages. There are also groups of connective tissue – tendons and ligaments – in close relationship with the parts of the bones. This article is mainly related to how bones work and how bones work.

Human bones, like those of other prehistoric organisms, have two main parts, each of which has a different origin than the other and each gives it its own shape. These are (1) axial, which has the vertebral column-backbone-and most of the skull, and (2) appendicular, where the lumbar (hip) and pectoral (shoulder) belt and the bones and cartilages of the legs. about. Discussed in this article as part of the axial skeleton is the third part, visceral, which contains the lower jaw, some elements of the upper jaw, and branches of the branches, including the hyoid bone.

When one considers the connection between these small parts of the bones and the soft parts of the human body—such as the nervous system, the digestive system, the respiratory system, the cardiovascular system, and the voluntary muscles of the nervous system—it becomes clear. that the functions of bones are of three different types: support, protection, and mobility. Of these services, support is the oldest and oldest; likewise, the axial part of the bones was the first to evolve. The vertebral column, similar to the notochord in lower organisms, is the main support of the trunk.

The central nervous system is located inside the axial skeleton, the brain is well protected by the cranium and the spinal cord and vertebral column, using the bones of the neural arches (bones that surround the spine) and the nerves. .

How Bones Communicate With The Rest Of The Body

A distinguishing characteristic of humans compared to other mammals is standing upright. The human body to some extent is like a walking platform on stilts, supported by legs. Great advantages have been gained from this vertical position, the main of which has been the liberation of tools for various tasks. However, this posture has led to many physical problems—mainly weight gain. These problems had to be overcome by changing the mask.

The protection of the heart, lungs, and other organs and organs of the chest presents a different problem than the central nervous system. These organs, whose function involves movement, extension, and bending, must have flexible and elastic linings. Such a cover is provided by the bony thoracic basket, or ribs, which form the bones of the chest wall, or thorax. The connection between the ribs and the chest bone – sternum – is always secondary, which is caused by the ribs that vibrate (costal) cartilages. The small joints between the ribs and vertebrae allow the rib cage to move during rest and other activities. Movement is limited by ligamentous structures between the ribs and vertebrae.

The third function of the skeleton is movement. Most skeletal muscles are attached to bones, usually to two bones and sometimes to many bones. Therefore, the movement of the body and its parts, from the peak of a football player to the skill of a hand painter or the use of complex tools by a scientist, is possible thanks to special and individual arrangements. muscles and bones.

In this article the parts of the bones are described according to their shared functions. Disorders and injuries that can affect human bones are described in the article on bone diseases. If you have ever seen a house being built, you will realize that the wood is the beginning of the structure. Just like the frame that makes up the roof, walls and roof of a house, our bones are also a strong foundation. Bones provide a strong support system that protects our internal organs and gives our muscles a connective tissue. If bones are the framework, then fat is what protects our body and skin is our walls. Just as insulation and walls protect the interior of our homes, bones, fat and skin protect our nerves, blood vessels and internal organs. Our skull protects the brain—like the roof—and our ribs protect the heart and lungs like the walls of our house protect us from the outside.

Skeletal System (human Anatomy): Picture, Functions, Diseases, And Treatments

Bones are hard on the outside, called compact bone, which provides strength and covers the inside of a sponge called bone marrow. Compact bone is hard, white and smooth. It gets energy from the calcium it stores. The bone marrow—which makes the white blood cells that make up our immune system and the red blood cells that carry oxygen to all of our organs—is like a sponge with many air sacs. These bags reduce the weight of our bones. If they were completely solid, they would be so heavy that we could not walk or run.

Our bodies were designed to move, so our bones are separated by joints and cartilage that allow us to bend, run, jump and dance. Cartilage, although very strong, is not as strong as bone or as flexible as muscle. We have cartilage between our ribs and spine, in the joints of our arms and legs, in our ears and in our nose. It works spontaneously and protects our bones from touching each other, which is very painful. Cartilage is the only tissue in our body that does not have blood vessels, which makes cartilage one of the slowest tissues to grow and heal. This is why recovery from joint injuries takes a long time.

Weight-bearing activities and physical activity can help keep our bones strong. Because the joint bone is the main place where calcium is stored in our bodies, it is important to eat enough calcium to build strong bones, especially at a young age. Up to 90 percent of bone growth occurs by age 18 in girls and 20 in boys. If we don’t get enough calcium, we can break our bones or develop osteoporosis later in life.

So, just like our houses, our bones also need regular maintenance. Keep your system healthy by exercising and eating a bone-building, calcium-rich diet.

A. Huey, PhD, FAPS, FACSM, is a professor of physiology in the Department of Health Sciences at Drake University in Des Moines, Iowa. His research focuses on contractile and cellular adaptations in skeletal muscle to changes and activation such as exercise or disuse and the effects of drugs on muscle function.

The word ‘peri’ means ‘around’ The prefix ‘endo’ means ‘found inside’ The suffix ‘blast’ means ‘to build’ Example: osteoblast (

Sesamoid bones are placed inside tendons or muscles and work to reduce tension and change muscle pull-E.g. patella.

Long bones are longer than they are wide, with a hole in the middle. These bones act as levers to create movement, make blood cells and store minerals-E.g. femur, tibia, fibula, humerus, ulna, metacarpals, metatarsals.

How Bones Work

Bone types are as wide as they are long. Their main function is to provide support and stability with minimal movement. For example carpals and tarsals.

Flat bones are made up of spongy bone between two thin layers of connective bone. As their name suggests, these bones are ‘flat’ in shape and have wide spaces for muscle attachment. For example
