The skeletal system is responsible for providing the structural foundation for the entire body. He or she is composed primarily of bones and connective tissue, which may include cartilage as well as tendons and ligaments, among other things. In certain circles, this system is referred to as the musculoskeletal system.
Several different functions are carried out by the skeletal system. It also gives us our human shape and characteristics, as well as the following:
- Your skeleton helps to support your body weight, which makes it easier for you to stand and move around. It takes the cooperation of your body’s joints, connective tissue, and muscles to keep the joints and body components of your body functioning properly.
- The bone marrow is in charge of the formation of blood cells, as previously stated. The bone marrow is in charge of the synthesis of red and white blood cells, among other things.
- Protection and support for organs: The skull protects the brain, the ribs protect the heart and lungs, and the backbone provides support for the spinal column and the rest of the body.
- Minerals are stored in the bones. Your bones are crucial for storing your body’s supply of minerals such as calcium and vitamin D.
Parts of the skeletal system
There are several various sections to the skeletal system that all work together to assist you in moving about. The bones, which are hard elements that serve as the backbone for your body’s architecture — the skeleton — make up the majority of your skeletal system.
- A strong membrane that covers and protects the outside of the bone is known as the periosteum (periosteum = “around the bone”).
- Compact bone: Compact bone is a type of bone that is white, firm, and smooth beneath the periosteum. It serves as a structural support and a protective barrier.
- Spongy bone has a softer core and inner layer than compact bone, which makes it easier to break. It possesses pores, which are small openings that allow marrow to be stored.
The following are the additional components of your skeletal system:
- Cartilage: This smooth and flexible substance covers the tips of your bones where they connect, protecting them from injury. It allows bones to move freely without causing friction (rubbing against each other). The loss of cartilage in the joints, such as that seen in arthritis, can be uncomfortable and create movement issues.
- Joints: A joint is defined as the point at which two or more bones in the body meet. Generally speaking, there are three different types of joints. Various types of joints are as follows:
- Immovable joints: Immovable joints, such as the joints between the bones of your skull, prevent the bones from moving at all.
- Joints that are only partially movable: These joints allow for only limited mobility. The joints in your rib cage are partially moveable joints, which means they may be moved.
- Movable joints: Movable joints provide for a greater range of motion than rigid joints. The joints of your elbow, shoulder, and knee are all movable.
- Ligaments: Ligaments, which are bands of strong connective tissue that join bones, hold the bones together.
- Tendons: Tendons are bands of tissue that connect the ends of muscles to their corresponding bones in your body.
Function of the skeletal system
The primary function of the skeletal system is to provide structural support for the body. The spinal column, for example, provides support for the head and torso during movement. However, when a person stands up, the legs are responsible for supporting and bearing the weight of their upper bodies. Some functions of the skeletal system are more easily observed than others, and this is true for both adults and children. When you move, you may feel how your bones support you, allow you to move more freely, and protect the soft organs in your body from injury. The bones and cartilages of your skeletal system serve as a scaffold to support the rest of your body, much like the steel beams of a building provide a framework to support the structure’s weight. A limp mass of organs, muscle, and skin would result if the skeletal system were to be removed. Bones aid in movement by acting as points of attachment for your muscles, which makes them quite useful. Examples include the protection provided by your ribs for your lungs and heart, the bones of your vertebral column (spine) for your spinal cord, and the bones of your cranium (head) for your brain and spinal cord.
Fat is stored in the bones, and blood cells are produced in the bone marrow as well. The term “bone marrow” refers to the special connective tissue that fills the interior of most bones and is found only in this region. A person’s bone marrow can be divided into two types: yellow bone marrow and red bone marrow. In addition to adipose tissue, the yellow bone marrow also contains triglycerides, which can be released from the adipocytes of this tissue and used as a source of energy for other tissues in the body when necessary. The formation of blood cells (referred to as haematopoiesis, from the Greek hematos = “blood” and poiesis = “to make”) takes place in the red bone marrow. The red bone marrow is responsible for the production of red blood cells, white blood cells, and platelets.
Conclusion
Bone, also known as osseous tissue, is a hard, thick connective tissue that makes up the majority of the adult skeleton, which serves as the body’s support system. Cartilage, a semi-rigid kind of connective tissue found in the parts of the skeleton where bones move (for example, the ribcage and joints), provides flexibility and smooth surfaces for movement in these sections of the skeleton.
