The Types Of Bone Tissue

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

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

A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011).

Spongy bone- has space between the plate ( trabeculae) bone, some of them are filled with red bone marrow example the strenum, rib, hip bones, and hear the end of the long bones in production of red blood cell. Sponge bones make up most of the bone tissue flat, short, and irregular bones

The long bone is composed of cartilage which covers both ends of the the bone(the epiphysis) and it helps prevents bones rubbing off each other (friction) and also is a shock absorber. The outer layer of the long bone is the hard compact bone, this allows the hollow part of the log bone some strength. The spongy part in the long bone ( in the epiphysis where the red bone marrow is stored , this allows for red blood cells to be produced. There's also a yellow bone marrow in the centre of the bone(marrow cavity) this allows for white blood cells to be produced. The shaft of the bone is also called the diaphysis. The periosteum of the long bone has no cartilage but also is a protective layer of the long bone , this is also where tendons and ligaments connects.

The bone tissue in osteoblasts is constantly being reshaped which form new bone when the previous bone has been fractured, making the new bone much stronger and harder to break. They are found in the bone marrow are known as structural cells. They work in a team to build new bone and produce new bone called ‘osteoid’ which is made up of bone college and other proteins. They have the power to control the levels of calcium and mineral deposition. When they are done filling in a cavity, the cells become flat and line the surface of the bone and then are called ‘lining cells’. They respond to hormones by making special proteins that activate the osteoclasts. Once they have secreted the matric they become less reactive and maintain the matrix. When the area surrounding an osteoblast hardens, the osteoblast becomes trapped and transforms into an osteocyte which is the mature type of bone

There are two types of bone tissue: compact and spongy. The names imply that the two types differ from each other in many ways. There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.

There are 5 types of bones in the skeletal system these are called long, short, flat, irregular and sesamoid bones. As shown in figure 9, long bones are longer than they are wide. They are 2 regions that form this bone, these are called epiphysis they is located at the top and bottom of the bone, and diaphysis that is located in the middle. These bones are located in places such as the femur, tibia, fibula, phalanges and ulna. Short bones are long as they are wide. These include the tarsal and wrist bones. Flat bones are broad bones

First, we need to understand what a bone actually is. You can hear bone-dry on a daily basis but actually bones are actually quite alive with nerves , blood vessels etc. Without bones in our body we would just be a blob and unable to move anything in our body. A bone divides into three layers periosteum, haversian canals and bone marrow. The first layer is the periosteum layer, it covers the whole part of the bone minus areas where cartilage connects the bone to a joint. The second layer is known as the Haversian canal which transports nerves and blood vessels throughout the human body. The third layer is known as compact bone or spongy bone, spongy

Osteocytes are the most abundant cell type in human bones and play a fundamental role in bone homeostasis. Representing 95% of all mature bone cells and have the longest lifespan in all bone cells, up to decades, osteocytes are the key to bone integrity1. They are initially derived from osteoblasts, residing within bones and take part in bone metabolism through excessive communication with other bone cell populations, including osteoblasts, osteoclasts and most importantly, osteocyte progenitors. Osteocytes secrete soluble signalling factors that regulate both bone formation and bone dissociation.

There is all types of bones in your body, here are a few types. Long Bones, short bones,flat bones, irregular bones and sesamoid bones. That's a lot of types of bones.

Bone close connection with the body’s metabolism. Bones contain a lot of calcium, phosphorus and other organic and inorganic, are participants and regulation of the metabolism of inorganic salt. Endocrine regulation of bone is also involved in the human body, affect hormone secretion and metabolism in the body. Bone is related to electrolyte balance in the

To study the longitudinal growth of a long bone, Duhamel inserted needles at equal intervals into the femur of a newly-hatched chick. Dissection of the femur of the chick, fifteen days later, revealed the impressions made by the needles to be separated by various intervals, smallest nearest the trabecular region and largest nearest the cortical bone because hardening begins in the trabecular of the bone and gradually proceeds towards the cortical bone. This proved that the different portions of the bone do not all grow equally but the trabecular bone grow more than the cortical bone. This phenomenon is now known as longitudinal bone growth.

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
