Understanding The Skeletal System

In this content am going to be talking and explaining the structure and function of the skeletal system. I will be talking about: Axial skeleton, Appendicular. Also highlighting the different types of bone such as long bones, short bones flat bones, irregular bones and sesamoid bones. I am also going to be talking about how your body is

The skeleton provides the framework of the body and it is made up of 206 bones. It is part of the skeletal system, which is composed of ligaments and cartilages, in addition to bones. Bones are connective tissues made of osseous materials that undergo calcification, a process where minerals are deposited to harden the bone. Cartilages are thick and rubbery tissues that are found in joints, the ears, the nose, and the ribs. Ligaments are tough, fibrous tissues that connect one bone to another bone, while tendons are soft tissues that connect muscles to bones.

The human body is made up of various bones; in total a person can have up to 206 bones ones the person has reached the adulthood. The skeleton is made up of two different groups which are the axial and appendicular skeleton. Both contain different bones in the body. The axial protects other parts of the body and appendicular skeleton helps the body with motion. Bones can come in different sizes and shapes. Along there are some bones called long bones, some short bones, others are flat bones and last there are what people call the irregular bones. The long bones contain two ends and they are considered longer then wider in cases. The short bones are shaped similar to square shapes but not exactly some bones examples can be the

Bones- provide support and keep shape, they undergo growth and development, Bones have an outer membrane, beneath the outer membrane is compact bone in which canals run through. The canals carry nerves and blood vessels to living cells inside the bone. Inside compact bone is spongy bone. Spongy bone is also found at the ends of bones. In the spaces of bone you will find bone marrow. There is red and yellow bone marrow. The red bone marrow produces

The skeletal system is a great supporter of the body. Without a skeleton we could not stand upright: everything would just be in a pool on the floor. The skeleton is extremely strong but incredibly light. The skeleton also helps protect the internal organs and fragile body tissues. Tissues such as the brain, the heart, eyes, lungs and spinal cord are all protected by the skeleton. Bones provide the structure for muscles to attach to so that our bodies are able to move. Tendons are tough inelastic bands that hold the muscle to the bone.

The skeletal system can be a wonder to many people, because of how much the bones of the body can endure, and even how a small fall can cause a break or a fracture. The human body has 206 bones, a complex system of tendons, ligaments and cartilage that connect them. The skeletal system has many different but vital functions like support, movement of the body, protection of the organs, calcium storage and also endocrine regulation the help us to move throughout our daily lives. The skeletons of adult males and females are different, mainly because of childbirth. Female adults have a flatter pelvis, is more rounded and also larger. A males pelvis is about 90 degrees or less of angle, where a female’s is 100 degrees or more. Bones can become easy to break when outside of the body, but bones are alive inside the body being supplied by the blood vessels from the circulatory system and nerves from the nervous system. A common bone has a tougher and dense outer layer, and the next layer is a spongy bone, which is lighter and slightly flexible. The center of some bones is a jelly-like bone marrow, where new cells are constantly being produced for blood. There are different type of specialist to help treat osteoporosis, which are an endocrinologist, rheumatologist, an ortheopaedic surgeon and physiatrists.

Our bones provide the structure which helps us stand instead of lying like a puddle on the floor. Other bones protect the delicate insides of our body. Without bones, you'd just be a puddle of skin and guts on the floor. There would no walking, no standing up, and no protection for internal organs. If it weren't for our skeleton, we wouldn't be able to move properly. Bones also have muscles attached to them, so in a way, muscles would be useless without bones. Bones store most of the minerals that the human body needs to function. Bone marrow stores essential fatty acids that the body uses for energy, as well as heavy metals and toxins, keeping them away from organs until they can be released from the body as waste.

Bones are dynamic organs, growing and continually remodeling throughout life. The responsible for the make-up of the skeleton are bone cells which are found within the bone tissue. Each cell type has a unique function and is found in different locations in bones, They are called osteoblast,osteocytes,and osteoclast.

The skeletal system of a grown human is made up of 206 different bones. The bones are attached together by tendons, cartilage, and ligaments. A bone is split into different layers. The outer layer of a bone is very sturdy and solid. The next layer is fairly malleable. The substance in the middle of a bone, is called bone marrow. Bone marrow is where blood cells are constantly being generated. If humans did not have bone marrow in their bones the tissues of the body could not generate ATP (Adenosine triphosphate). ATP is how energy is used and stored away. The skeletal system is very important for everyday functions such as movement, protection of internal organs, and support, which is needed for survival. Without the skeletal system we would

The skeletal system gives our body protection and provides us with a framework. Our body contains 206 bones. The bones are important because they produce blood cells and maintain necessary nutrients. Inside of our bones we have two types of tissues. Compact bone tissue is tough and hard. It can be found in our arms and legs. Spongy bone tissue is made up of plates and contains red bone marrow. Our skull has 22 bones and it protects our brain from injuries. The spine is in our back and it connects to our skull. The rib case is another important part of our skeletal system because it protects our vital organs such as the heart, lungs and liver from damage. I think about all the times I played sports as a teenager and had our ribcage not been there I’d be dead or seriously hurt. Amazing how it helps us to get through our daily

The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).

Bone tissue also known as osseous tissue serves to protect and support. According to Elaine Marieb and Katja Hoehn’s book (2016) bones have seven important functions which are: support for organs; protection for the brain, spinal cord, and vital organs; movement of the body; mineral and growth storage such as calcium and phosphate; body cell formation such as blood cell formation (hematopoiesis); triglyceride (fat) storage which is then used as an energy source; and hormone production such as osteocalcin. There are different shapes of bones like long bones, short bones, flat bones, and irregular bones. Long bones are bones that are longer in length than in width while short bones are bones that are shaped somewhat like a cube. Flat bones are bones that are flat and thin while irregular bones are differently shaped bones with no specific shape. All the bones in the human skeleton are also separated by location. The axial skeleton consists of the rib cage, vertebral column, and the skull which in all, forms the long axis of the body. The appendicular on the other hand, consists of the limbs, pectoral girdle, and pelvic girdle. The bone also consists of two layers, which are the compact bone and spongy bone. Compact bone is the outer layer which is smooth and solid while the spongy bone, the inner layer has the appearance of a “honeycomb”.

The primary cellular components of bone tissue are osteoblasts and osteocytes, and these are distinguished by their location and their function.1 The osteoblast is the bone-forming cell that eventually becomes an osteocyte. During this intermediate changeover, the cells are referred to as intermediate cells. “Bone matrix is comprised of three elements: organic, mineral, and fluid. Organic components constitute 39% of the total bone volume, which contains 95% type I collagen and 5% proteoglycans. Minerals include primarily calcium hydroxyapatite crystals and contribute about half of total bone volume.”1 Within the matrix, collagen fibers are responsible for providing tensile strength. Eventually, calcification and ossification of the fibrous matrix forms individual bony trabeculae that together constitute a primary ossification center.2 The arrangement of the collagen/trabeculae along the length of the bone give the bone its tensile strength; the resistive strength against bending/breaking.1,2 The density of the bone is provided by calcium salts which are necessary to provide resistive strength against compressive forces, such as load/weight bearing activities.1 Stresses from weight bearing and using muscles provide the necessary stimulus for the formation and organization of collagen/trabeculae to form architecturally strong bones. Typically, when no injury or disease is present, bone

The skeletal system includes the osseous tissues of the body and the connective tissues that stabilize or interconnect the individual bones. The bone is a dynamic tissue. Throughout the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of growth and remodeling.

Have you ever thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to two major category: the axial skeleton and the appendicular skeleton. The axial skeleton has 80 bones in the midline axis which contains the bones of the head and the trunk; while the appendicular axis has 126 bones which include the bones from the limbs, pectoral and pelvic regions. There are only a few select bones that are mainly affected by the Paget disease these include the pelvis and the tibia which belong to the appendicular axis; however, other bones that could be affected are the femur, spine, skull, clavicle, and fibula.
