Skeleton Key Components

Cartilage tissue is a smooth, firm substance that protects ends of the bones from friction during movement and they can be found at the end of our bones in mobile joints, the front ends of the ribs, also in parts of our nose and ears.

Cartilage doesn’t contain any nerves or blood vessels and is surrounded by a layer of dense irregular connective tissue, the perichondrium (Marieb, 176). Bones contain various types of tissues which makes them organs. They are used for support, protection, movement, mineral storage, and blood cell formation (Marieb, 178-179).

These muscle tissue cells specialised to contract and move parts of the body. It is also capable of responding to stimuli. There are three types of muscle in the body such as: skeletal, cardiac and smooth. Each muscle is created of muscle fibers that are capable of contracting and returning back to original state-relaxation. Contraction causes movement of the skeleton, soft tissue, blood or specific material. Skeletal muscle is attached to the bones of the skeleton. Some facial muscles are attached to the skin. They have direct control over them through nervous impulses from our brain sending messages to the muscle. Contractions can vary to produce fast, powerful movements. These muscles also have the ability to stretch and contract to return to original shape. Cardiac muscles are found in the chambers of the heart such as the atria and ventricles. It is under the control of the automatic nervous system; however, even without nervous input contractions can occur. It is completely different to all the other muscles. Smooth muscles are also known as involuntary due to our inability to control its movement. This muscle is usually found in the walls of hollow organs

It consists of the shoulder gridle, the arm and hand, the pelvic girdle, the legs and feet. The parts in red in the image are where the appendicular bones can be found in the body. There are two hundred and six bones in the skeletal system. The five main types of bones are; Long bones, short bones, irregular bones,

The quads include the rectus femoris, and the vastus lateralis, intermedius, and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity, and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation, and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the knee joint is the strength of the quads. The only muscle that assists in extension is the tensor fascia lata.

Compact bone is the hard external layer of all bones that protects and surrounds the medullary cavity filled with marrow.

Hyaline (articular) cartilage is resilient tissue found on the end surfaces of all bones that

Cartilaginous joint is connected by the cartilage and is also known is the slightly moveable joint. It allows little movement between joints in places such as the vertebrae and ribs.

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

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
