Skeletal System Quiz

1- A function of the Skeletal System that is essential to life is the bones because there are many functions of the bones such as support , protection, movement, blood formation, detoxification, and mineral storage and balance.

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 skeleton stores mineral and fat. All bones have a matrix that contains calcium phosphate that serves as a source of calcium and phosphate ions for the blood. Fat is stored in the

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.

2. The Skeletal and Muscular systems - The skeletal system’s goal is to give the body posture. However, the muscular system connects to the bone and helps move the arm. For example, Biceps and triceps connect to the shoulder and the radius and ulna to lift and lower your arm. In order for proper function, your body must only contract either the biceps or triceps at once. Additionally, the biceps and triceps would lie limp without the support from the bone. This is because the muscle can only constrict and relax. For this reason, they can’t move any limb without bones.

The chicken leg bone got more bendable and jelly-like because the acid destroyed the calcium in the bone.

The framework of the human body is the skeletal system. Skeletal system organs include the bones, joints, cartilages, ligaments, tendons and teeth. Bones offer support for the muscles, protect our vital organs, and allow us to eat food. Our joints allow our body to move, twist and bend. Cartilage, like our ears and nose, offer soft structures that are more malleable than bones. Two separate bones are connected by ligaments, and bones and muscles are connected by tendons. Our teeth allow us to bite and chew our food. Skeletal structure is similar among all people around the world, with the greatest diversity occurring between the sexes. We will explore each system in greater detail and provide

bones are essential as they surround internal organs e.g. your heart which stops them from getting damaged. Bones are a living tissue which is muscular and firm; slightly to resist breaking. The bones get their strength from storing minerals e.g. calcium and phosphorus. They produce blood cells which help the body fight against infections. Your bones allow you to walk and run as they work together with muscles. Bones can be flexible as well due to collagen. This makes it hard for the bones to break. However, bones can easily become brittle and this can be due to old age but when

The skeleton is the framework of bones, it structures the body, support to the body and protects the internal organs of the body. It also allows the muscles to move freely during the mechanism of locomotion.

Bone tissue is made up mainly of fibrous collagen connective tissue surrounded by a calcium phosphate-like mineral. It is hollow shaped structured that cannot swell or shrink. However, there are living cells and blood vessels imbued within the bone tissue.

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).

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.
