composition of bone mostly consist of inorganic material and collagen fibers. The macroscopic structures of bone is Compact bone‚ Cancellous bone‚ Epiphysis‚ Diaphysis‚ Periosteum‚ Red bone marrow‚ yellow bone marrow‚ and the articular cartilage (Doitpoms.com). Collagen is a triple helix structured protein that is the most prominent protein in the skeletal system. Bones consist of two distinct types of bone tissue such as cancellous and cortical bone. Cancellous bone is also known as spongy bone and is located

Bone Breakdown Before taking a human anatomy and physiology class people think of a bone as a simple structural part of the body. When in reality bones are very complex and can be classified into multiple groups. The many groups they are classified into are their shapes. There are four main shapes of bones to be classified as; long‚ short‚ flat‚ and irregular. All these classifications are especially different but two of them are somewhat similar; being the long and short bones. The long bone

Bones support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones. Bone cells are the living units that make up your bones and keep them functioning. Bone cells have two major roles‚ which are the production of new bones and resorption or destruction of old bone. They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves

body‚ as such‚ the organisation of the bone tissue is very important. Bone tissue can be broken down into macroscopic and microscopic organisation. Working from the superficial surface to the median of a bones anatomy‚ macroscopic tissue structure is organised as follows; compact bone‚ spongy bone‚ the medullary cavity and on the surface of the compact bone at the distal and proximal epiphyses of long bones is the connective articular cartilage. The compact bone is the supportive‚ protective shell

BONE CANCER The human body consists of 206 bones. Each individual bone functions differently. The body bones are arranged so that they help to support and guard many organs. The bones too function as a muscle attachment‚ which helps during movement. The most significant function of a bone is being able to produce and store cells in bone marrow. Healthy cells grow‚ split‚ and increase through out the body. Body tissue is made of cells. Nonetheless‚ several cells may be irregular. Although healthy

types of bone in the human body‚ first we have long bones‚ some being the longest bones available in the skeleton such as the tibia and femur but are also some of the smallest bones such as the metacarpals and metatarsals. The description best suited to long bones would be that they are longer in length than they are in width‚ with epiphysis at either end. (The bones growth plates). The inside of the bone is a spongy like substance known as cancellous bone which is where the bone marrow is found

Topic 1 In anatomy and physiology‚ one of the things you will learn about is bones. Bones do so much for a person and they can even do things for you after death. This semester we discussed bones. We labeled the human skeleton and that allowed us to be able to see where each bone is and what is does for the body. We learned things such as the functions of bones which is that they support and protect soft tissues‚ store inorganic salts‚ form passageways‚ provide points of attachment for muscles‚ and

the bone marrow‚ yes this is a type of cancer. Bone marrow cancer occurs with the enlargement of cells on a healthy cell. cancer is something that is extremely hard to cure‚ bone marrow cancer is twice as hard to cure not only that but it is a risky and dangerous process. Bone marrow also called myeloid tissue‚ soft tissue that is
