An articulation is the weakest point on the skeleton however the structure is capable of resisting strong forces that may threaten its normal alignment . A normal structure of a joint includes a coated layer of tough, slippery tissue that coats the ends of each bone known as an articular cartilage. A cartilage acts as a shock absorber and keeps the end of the bones from being crushed. For instance the knee, also known as the biggest and most complex joint in our body has an extra cartilage known as a semi-circular cartilages, these cartilages or menisci helps with the prevention of the femur to rock side to side on the tibia as well as acting as a shock absorber .
Appositional bone growth occurs in this area because the bone is being remodeled with an increase in diameter as new bone is being laid down. Osteoblasts, osteocytes and osteoclasts are the cells that would be found in this area to help with bone remodeling. 3. Describe the microscopic features of the osseous tissue that help long bones withstand compressive
The calcified matrix and moribund chondrocytes break down and lacunae become confluent. An enlarging cavity is produced in the cartilage model. Blood vessels penetrate the bony collar through channels on the spongy bone. The enlarging cavity in the middle of the cartilage model becomes vascularised and myeloid cells become established, forming the marrow cavity.
Cartoon Character Skeletal System Project Essay! The human skeletal system consists of 206 bones and associative tissue such as joints, cartilage, ligaments, and tendons. Each bone is a complex living organ that is made up of cells, minerals, and protein fibers. When joined together, the skeletal system provides the base framework, giving shape to the unique human body and provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachments points for muscles enabling movements at the joints.
However, when we look at the “stuff” that holds us together, things make sense. Said “stuff is very complex to explain, but in a nutshell it is talking about the molecules that allow cellular arrangement and communication possible. In order to better explain this concept, Neil decided to focus on one part, the skeleton, due to its impact on the entire structure of our bodies. He explains the bone’s structure by explaining the functions of the three basic molecules of bones: hydroxyapatite, collagen, and cartilage. Hydroxyapatite aims to maximize the bones compressive functions.
However, bones can be classified by shape, structure, and bone markings. Bones are categorized as sutural, irregular, short, flat, long, and sesamoid bones based on their shape (Martini et al. 180). The long bones contain a diaphysis, epiphysis and metaphysis. The diaphysis in the long bone is made of compact bone which has a medullary cavity where marrow is kept. The epiphysis of a long bone is made of spongy bone is an open region of trabecula
Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed.
The symptoms can vary and the symptoms can worse on some days and not really noticeable on others. If the condition is serious, the pain may not go away and it may affect you in your everyday life. For example, it may stop you from sleeping through the night and could cause difficulties when trying to carry out daily tasks like climbing
Pain will cause the joints to hurt before and after your movement. Your joints will be stiff in the morning, when you wake up, causing no urge to get out the bed. Loss of flexibility will cause difficulties moving yours joints in a full rotation. The causes of osteoarthritis can cause the cartilage in your joints to break down. For

Bone broth rich in red marrow provides those stem cell factors which ultimately build your body’s strength and support your immune function A dash of apple cider. ; Bone is an excellent source of calcium and phosphorus, and to a lesser degree, magnesium, sodium, potassium, sulfate and fluoride In the digestion process, hydrochloric acid helps to break down food in the stomach but is also necessary to extract elemental minerals from food.
Despite what we think about when we hear “arthritis,” the truth is that it’s almost impossible to paint just one picture to explain what it looks like. There are over one hundred varieties of arthritis, and anybody can get the diagnosis at any time. To me, that’s a scary statistic, especially when we consider an “old person’s” disease can affect someone as young as ten years old. For many people, arthritis is not the bone spurs or the incredible pain that crosses over them when they move their body.
