What Is Skeletal System And Its Function – The skeletal system is the body that includes bones, cartilages, ligaments and other things that perform important functions for the human body. Bone tissue, or cartilage, is a hard, dense connective tissue that makes up most of the skeleton, the supporting structure in the body. In the parts of the skeleton where all the bones move with each other (for example, joints like the shoulder or between the bones of the spine), cartilages, a semi-solid form of connective tissue, are provide flexibility and smooth surface for movement. In addition, the ligaments are made of thick connective tissue that surrounds these joints, tying skeletal elements together (the ligament is the thick connective tissue that connects bones to other bones). Together, they perform the following tasks:
Some functions of the skeletal system are easier to observe than others. When you move you can feel how your bones support you, facilitate your movement, and protect your soft tissues. Just as the steel beams of a house provide a scaffolding to support its weight, the bones and cartilage of your skeletal system form the scaffolding that supports the rest of your body. Without the skeletal system, you would be a weak mass of organs, muscles, and skin. Bones facilitate movement by being the attachment points for your muscles. 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 spine, and the bones your cranium (skull) protects your brain (see Figure 6.1.1).

What Is Skeletal System And Its Function
On a metabolic level, bone tissue performs important functions. For one, the bone acts as a reservoir for many important minerals in the body’s activity, especially calcium, and phosphorus. These minerals, incorporated into bone tissue, can be reabsorbed into the bloodstream to maintain the necessary levels to support body processes. Calcium ions, for example, are necessary for muscle contraction and are involved in the transmission of nerve impulses.

Bones are also a place of fat storage and blood production. The special connective tissue that fills the inside of most bones is called bone marrow. There are two types of bone: yellow bone and red bone. The yellow bone marrow contains the body, and the triglycerides stored in the body of this substance can be given as a source of energy for other tissues. the body. Red bone marrow is where the production of blood cells occurs (called hematopoiesis, hemato- = “blood”, -poiesis = “to make”). Red blood cells, white blood cells, and platelets are all produced in the red bone marrow. As we age, the distribution of red and yellow bone marrow changes as seen in the diagram (Figure 6.1.2).
Figure 6.1.2 – Bone Marrow: Bones contain variable amounts of yellow and/or red bone marrow. Yellow bone marrow stores fat and red marrow is responsible for producing blood cells (hematopoiesis).
A chiropractor is a doctor who specializes in diagnosing and treating disorders and injuries related to the musculoskeletal system. Some physical problems can be treated with drugs, exercise, protection, and other devices, while others can be better treated with surgery (Figure 6.1.3).

Although the origin of the word “correction” (ortho- = “correct”; paed- = “child”), it literally means “correction of the child,” pathologists can find patients who from children to adults. In recent years, obstetricians have also performed operations to correct spina bifida, a rare condition in which the spinal cord of the fetus does not close completely during the development of the fetus. embryologic.
Orthopedists often treat bone and joint injuries but they also treat other bone conditions including curvature of the spine. Back curvatures (scoliosis) can be so severe that the shoulder blade (scapula) slips upward, like a hole. The arch of the spine (kyphosis) can also cause slouching and stiffening of the body. These folds often appear in children before puberty due to poor posture, growth retardation, or unknown causes. In most cases, it is easily treated by medical professionals. As people age, developing eye injuries and diseases such as osteoporosis can also lead to spinal stenosis, the this is the bending you sometimes see in older people.
Some orthopedic surgeons specialize in sports medicine, which treats both simple injuries, such as ankle sprains, and complex injuries. , such as tearing the shoulder. Treatment can range from exercise to surgery.
The major functions of the skeletal system are to support the body, facilitate movement, protect internal organs, store minerals and fats, and build blood cells.

Let’s talk about support for you, your students, and the human body. Humans have an internal skeleton consisting of 206 bones and cartilage and connective tissue in the form of ligaments and tendons that connect bones and muscles to bones. The skeleton provides support for the body, protects organs and soft tissues, and facilitates movement. In addition, bones store minerals and some bones produce blood cells. Bone tissue is classified based on structure into small bone and cancellous bone.
Students often do not integrate the roles of the muscular system and the skeletal system in facilitating movement. It is actually a mechanical problem that determines the opposing forces needed to contract and relax the muscles that move the bones. To help with your learning, we have a simple, free activity that demonstrates the relationship between the skeletal and musculature systems that students can also some information in the field of biomechanical engineering.
Joints And Skeletal Movement
For more advanced research on the interactions of the skeletal and muscular system, see the Interactions of Muscles and Bones Kit where students explore the biophysics of the elbow and hand.
Practical examples are a great way to support students as they explore and review the workings of the skeletal system. We have many human skeleton models in various sizes, but the best is the life model. It gives students the perspective they need to connect the structure to the work. As the focus moves on to injury and disease, detailed models of joints and connective tissue help students see how and why injuries occur. At the microscopic level, bone specimens and microscope specimens show the complexity of bone structure. A study of the skeletal system can be more than just memorizing the names of the bones in a chart. Involve your students in a wide variety of activities and events.

Skeletal System Puzzle With Descriptions
Bones have a hard outer layer, called the cancellous bone, that provides strength and covers a spongy interior called bone marrow. Solid bones are hard, white and smooth. It gets its energy from the calcium it stores. Bone marrow—which produces 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 tiny air sacs. These actions reduce the weight of our bones. If they were fully strong, they would be so heavy that we couldn’t walk or run.
Our bodies are designed to move, so our bones are separated into joints and cartilage that allows us to bend, run, jump and dance. Cartilage, although very strong, is not as hard as bone or flexible as muscle. We have cartilage between the bones of our bones and the bones, in the joints of our hands
