Hello Nellie! Your Auntie Rayna here! I heard from Aunt Gladys that both of you were making fried chicken, and it made you wonder about how broken bones heal. I, also, heard you were wondering how bones grew after you saw some unborn chickens and their broken eggs. I’d love to tell you how our bones heal, but first, let’s go over how they begin their “life” cycle into becoming an actual bone. When we are born, our bones start out as hyaline cartilage (hyalos- meaning glass). You can think of hyaline cartilage, in this case, as the “framework” for the future bones. This cartilage is formed by multiplying cells called chondrocytes. This rapid cell division, then, helps our framework grow. This growth occurs in the epiphyseal plates located near the ends of these growing bones. This is associated by two different names: interstitial and appositional. Interstitial growth is when those chondrocytes divide, and this increases the length of our soon-to-be bones. On the opposing side, we have appositional growth, which helps in adding thickness to our bones. (I’ll go into this more a little bit later.)
As we age, the cartilage slowly begins to transform

With this formation, articular cartilage can be found at the ends of our joints, like our knee, for cushion, and it allows for our joints to move without discomfort. Then we have the inside of our bone, which is hollow and allows for blood vessels to penetrate and provide nutrients. Previously referred to in this letter as spongy bone tissue, this tissue has a lattice-like pattern. What may be easier to think of would be your favorite waffle fries from Chik-Fil-A! It is strong, but not as tough as our other type of bone tissue, compact bone tissue. Compact bone covers the spongy bone and provides a tough exterior for one main function: protection. You can think of compact bone as spongy bone’s protector. This is the outer bone that you felt when you were coating the chicken
In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
As the matrix hardens, it forms lamella, a tube of the solidified bone matrix, which forms the lamellar bone. Essentially, lamellar bone is lamellae with collagen fibers surrounding each lamella. It is important to know that collagen fibers on one layer, run parallel to the collagen fibers on another layer. For this reason, lamellar bone is very tough. The lamellar bone is located on both sides of the spongy bone and thickens around the trabeculae. The blood vessels are still situated within the spongy bone and form the red marrow. If a lamellae form around a blood vessel, it creates an osteon with a central canal where the blood vessel is
Bones are dense and provide support and structure to the body. The two types of bones is compact and spongy bones. Compact bones are dense and tough. Spongy bones are not as dense and are flexable. Bone remodeling occurs n 120-day cycles. Over the first 20 days resorption by osteoclasts occurs. Osteoclasts release proteases, clears away damaged bone, and releases matrix-bound growth factors. Bone formation occurs by osteoblasts over the last 100 days. Osteoblasts fill in bone cavity with bone matrix.
The main point of this informative speech was how Medical Robots are changing modern medicine. The first point the speaker showed the audience is how the Medicial Robots help Maurine get a new kidney. The next point he tells the audience is how orderly robots are suppose to transport medicine, food and lab supply. The next robot he tells us about is the remote present robot. Remote present robot helps the doctor be with the patient even if they are not in the same hospital. The last robot he tells us about in his speech is the surgical robots. These robots are used in operating rooms around the world. The speaker did a great job of not speaking to fast or too slow, and he also made eye contact with his whole audience instead of looking down
Lupus is known as “the cruel mystery” in the world of disease/medicine. 1.5 million Americans are currently diagnosed with Lupus, with the number possibly being a lot higher since it is one of the most difficult diseases to diagnose in the WORLD (5 Million some form of Lupus)
To protect different sections of the body there are 5 types of bones that serve a specific function for the system. The first type is long bone. Long bones are hard bones that provide strength, structure and mobility. (Medicine Net) These bones are longer than they are wide and they are mainly located in the appendicular skeleton. They also consist of several sections which are Diaphysis, epiphysis, metaphysic, and epiphyseal plates. The diaphysis is the long central shaft. Next, Epiphysis forms into the large ends of long bones while the area between the diaphysis and epiphysis is also known as metaphysis. Lastly, epiphyseal plates are plates of cartilage that allow growth to take place during childhood years. Cartilage cell production stops when the human body stops growing and the plates eventually become replaced by bone. Flat
Specific Purpose: To help people to understand what Audism is and that the lack of an ability to hear does not mean they are incapable of performing tasks.
Spongy bone or cancellous bone, much lighter than compact bone, provides the body support and flexibility. The cancellous bone may turn into compact bone through osteoblasts
Osteoporosis is a serious disease that leads to a faster than normal loss of the bone density, which puts the bone at a higher risk for fractures. In order to understand the causes of Osteoporosis, it is important to understand how bones are formed. Bone is a living tissue that is made mainly of collagen, calcium phosphate, and calcium carbonate. The mixture of collagen and calcium gives the bone strength and flexibility. The body deposits new bones and removes old ones; moreover, there are two types of bone cells that control the reproduction of bones. Cells called osteoclasts breakdown bone tissues thus, damaging the bone. Once the damaged bone is removed, cells called osteoblasts, use minerals including calcium and phosphate from the blood stream to make new healthy bone tissues. In order for osteoblasts and osteoclasts to work properly, hormones such us thyroid, estrogen, testosterone, and growth hormones are
Cartilage serves as protection against bone on bone contact to prevent wear in bones an example of this is the lateral and medial meniscal cartilage (articular cartilage). But the lateral and medial meniscal cartilage can be quite easily torn although a common injury in fully grown adults torn cartilage cannot be healed as cartilage receives little blood flow making it hard for it to heal compared to children with
The food we consume everyday has a vitamin and the mineral that our body can store and can store directly into our bones. In a bone, there is a space within the shaft and that’s where the most of the vitamins are stored in. “Bone is a reservoir for minerals, most importantly calcium and phosphate” (Marieb 176). The minerals that are stored will released into the bloodstream to distribute to the parts of all body. Blood cell formation occurs in the marrow cavities in certain bones (176). There are two types of bone marrow: red marrow, which consists mainly of hematopoietic tissue and yellow marrow which consists of fat cells. Red marrow, Hematopoietic tissue is found in the trabecular cavities of the spongy bone. Red marrows are typically found in the long bones and in the flat bones of spongy bones. At birth, all bone marrows are red and as we age over the years, more and more of its red marrow converted to yellow type. The blood cell production in typical adult bone happens in the head of the femur and humerus because the “fat containing medullary cavity extends into epiphysis and not much red marrow is present in the spongy bone cavities” (179). When osteoclasts break down the bone, tis mineral components like calcium and phosphorus will be sent back into the blood
Describe the microscopic features of osseous tissue that help long bones withstand compressive forces without breaking.
Today I’m going to inform you about X-ray Technology its history and how it been advancing since it’s been invented. Also will inform you how it is currently helping doctors and their patients.
Bone homeostasis occurs when the bones are being “remodelled” or it is also known as “bone metabolism” this is the process in which new bone is created and the old bone which was there was removed, it is more common to see this process in younger growing children or adults who have broken any bones.
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
