The Skeletal System

The skeletal system, while appearing inert at first glance, is a dynamic organ responsible for a number of vital functions in the body; including but not limited to providing protection and support to other organ systems, as well as permitting movement through collaboration with the muscular system. At the cellular level, bone provides a reservoir of growth factors and cytokines, maintains the acid-base balance and mineral homeostasis, and is the site of hematopoeisis. Like other connective tissue, bone has both a cellular and an extracellular matrix component. The matrix is made up of collagen fibers and noncollagenous proteins, with type I collagen accounting for ~90% of total protein, and the noncollagenous osteocalcin, osteopontin, and bone sialoprotein, and others making up the other 10%. In contrast with other connective tissue, the extracellular matrix of bone is mineralized physiologically, though the deposition of layers of carbonated hydroxyapatite. This mineral component, making up 50-70% of bone, provides bone 's characteristic mechanical rigidity and strength (Clarke 2008). Elasticity and flexibility are due to the organic matrix, which makes up another 20-40%, lending bone incredible resilience without compromising its strength, and another 5-10% of bone is water.

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 skeletal system works as the frame of the body and it is made up of two hundred and six various bones. The Sections used in the movements of the skeletal system are; the bones, Joints, ligaments and tendons. This system is also divided into two sections known as the Axial and Appendicular skeleton.

Although a fracture is also known as a broken bone, there are many types of fractures. Some types of fractures are more severe than others, all of them must be seen immediately. Fractures happen at least twice in our lives. Some types of fractures are also caused by age or osteoporosis which is the weakening of the bones (Melinda, 2015). The severity of a fracture depends on the strength with which the fracture was caused. A bone could be fractured in many ways such as lengthwise, crosswise, and also in multiple pieces (Stuart James, 2012).

Exploring the Skeletal System The precise number of bones in the adult human skeleton varies from one person to another, but on average there are 206 bones varying shapes and sizes. The skeleton is divided into two main parts. The central bones of the skull, ribs, spin (vertebral column) and breast bone (sternum) form the axial skeleton. The bones of the arms and legs, along with the shoulder blade (scapula), collar bone (clavicle) and pelvis make up the appendicular skeleton.

1. The Integumentary and Skeletal systems - The integumentary system depends on skeletal system to supply the red blood cells. The bones make red blood cells that take oxygen and nutrients to the dermis which is the under-layer of skin, which is still alive. On the other hand, the skeletal depends on the skin to absorb vitamin D. The blood can then transfer it to the bones why it is used to support bone structure.

2. What does each structure contribute to the functioning of the whole skeletal system and the whole body?

Skeletal bone is a dynamic tissue structure that constantly undergoes changes and remodeling throughout someone’s lifespan. Skeletal bones is a mechanical support for locomotion and protecting the organs. Muscle tendons and ligaments insert onto the bone. It is only present in vertebrates.

The skeletal system haves 6 primary functions. which includes support, protection, movement, mineral homeostasis, blood cell protection, and storage. All of these functions are a big part of our body and are helping us out even if we don't know they are. The “support” function provides structural support for the entire body. The “mineral homeostasis” stores calcium and phosphorus. The “blood cell production” is the red bone marrow which produces red and white blood cells and other elements. My favorite function is “protection” because it provides soft tissue around the heart, lungs, ribs, and most importantly the brain. Another one of my favorites is “movement”, because i like to move and i'm a really busy person and just cant stay still.

The skeletal system is made up of 206 bones which protects, support and allows the human body to move. The skeletal system also consists of tissues such as; tendons, ligaments and cartilage - these components connect the bones together which results to the posture and framework of the body. The skeletal system of a new born baby consists of more bones than an adult (roughly 300 bones); this is because the bones have not been joined together by the tissues. As the human body grows, the smaller bones are joined together to form larger bones in the body. Teeth are also a part of the skeletal system - they are made of dentin and enamel. Enamel is the strongest substance in the body. The structure of the skeletal system on a whole consists of ligaments, tendons, cartilage, joints, sockets and bones which all interrelate and play a massive part in the functioning of the body by protecting the internal organs and allowing the body to maintain balance and posture.

The skeletal system consists of bones, joints, and associated cartilages. These provide shape and support for the body and protect internal organs and structures. The marrow cavities within some bones serve as the site of hematopoiesis. The also skeleton serves as the reservoir of calcium and phosphorus. A common pathology of the skeletal system is rheumatoid arthritis (RA). It is a chronic systemic disease characterized by autoimmune inflammatory changes in the connective tissue throughout the body. • Celecoxib (Celebrex) is a type of non-steroidal anti-inflammatory drug (NSAID) that will directly target cyclooxygenase-2, COX-2, an enzyme responsible for inflammation and pain. Celecoxib is available in 50 mg, 100mg, 200 mg, and 400 mg capsules.

The skeletal system purpose is to allow the body to move, it gives the body a shape and helps to support. It additionally provides protection to vital organs and plays a role in blood cell production. Bones store calcium and encourages endocrine regulation. (Zimmerman, K,. 2016)

It provides stability and allow the human body to move. It consists of the body bones, skeleton, muscles,

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an

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.
