Skeletal System

Our bone tissues are made of a much harder substance than the cartilage, but they can be worn away by friction. They are tough on the outside, but on the inside they have a sponge-like design that helps to reduce the weight while retaining strength. They are designed to maintain the body’s structure and support the body’s movement and are used to protect weaker tissues, such as the brain, lungs and heart.

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

Osteoblast- cells which build bone by removing calcium and phosphates form the blood in the presence of the enzymes alkaline phosphates secrete by

In this exercise, we will examine a fresh raw chicken bone to study bone

It also protect soft internal organs for an example brain and heart from injury. Skeleton with muscle is strong bones that can enable the body to move freely. Individuals who is at increase risk for fractures may be difficult to heal because of the weakened bones. This can lead to loss of mobility, the inability to retain independent living and even death. Osteoporosis can gives a huge effect to human skeletal due to decreased mineralization of the bone. Human skeletal consist of two types of bones which is compact bones and spongy bones. Compact bones is a bone that has a solid outer surface while spongy bone is inner bone that less dense than compact bone which has many holes like sponge. A spongy bone does not have osteon.The matrix forms an open network of trabeculae. Healthy bone is dense enough to support and protect body and to handle stresses of movement and minor injuries while osteoporosis has abnormally thin bones with larger holes on spongy

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 has 6 main functions and makes up 18% of the overall weight of the human body. (Tortora and Derrickson, 2011)

Bones possess five important functions including, support, protection, movement, storage and blood cell formation (Marieb, 2012). Bones protect and support the body by acting as a rigid framework surrounding delicate organs and tolerating enormous pressure when weight bearing and moving (Marieb, 2012). Bones are also responsible for storing fat, minerals and producing blood cells (hematopoiesis) within the cavities of bone marrow (McCance & Huether, 2014) (Marieb,

Introduction. The skeletal system consists of the bones, along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints.

Bones are structured to provide strength, protection, and movement. In addition the structure allows the bones to serve as a reservoir for several minerals including calcium because calcium can quickly move between the bone and the blood.

Bone tissue is hard and has a calcified matrix (where the pores are filled with calcium) containing collagen fibers; osteocytes (mature bone cells) lie in the lacunae (cavity containing bone cells). The key functions of bone tissues are: support and protect the body structure and provide cavities for fat storage and synthesis of blood cells. Because the matrix of bone tissue is hard and rigid, the tissue is able to provide support and protection to the

2] There are four main types of bones. Jenny’s has fractured her long bone which is the left humerus at the proximal diaphysis, her flat bone which is occipital bone and an irregular bone at the 3rd

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.
