Four Bone Cells

Bones are made up of 25% water and 75% solids which consists of cells and mineral salts (calcium

The skeleton is made up of bones, which provide support and shape to the body. They play a key role in protecting soft internal organs, such as the brain and heart from injury. Together with muscles, strong bones assist the body to move freely and easily. People have their strongest, most dense bones in their thirties. However, once a person starts to age, the bones start to deteriorate, which puts one at high risk of fractures, disease and breakage.

Bone is covered with a living membrane called the periosteum this contains bone-forming cells, the osteoblasts. The centre of bone contains marrow. This where blood vessels, fat cells and tissue for manufacturing blood cells are all found. There are also four main shapes of bones. Flat for example the ribs, irregular for example the vertebrae, short for example the hand carpals, long for example the upper are humerus.

Bones are living tissue composed of living cells because of this they are a complex source of a wide variety of nutrients. They contain minerals which are embedded in protein, fat and fat soluble vitamins. They are a great source of calcium, copper, iodine, iron, magnesium, zinc, and manganese. The central part of most bones contain marrow which is a highly nutritious source of blood forming elements. They also provide natural antioxidants including enzymes. Pets fed bone rarely suffer from indigestion or diarrhea. Bones play a similar role to fiber which helps remove toxins promoting bowel health. Pets fed bones are long lived healthy animals that seem to be particularly free of degenerative diseases. Common bones can include chicken backs,

What is the structure of the skeletal system? The skeletal system is made up of two parts, the first is the Axial skeleton and the second is the appendicular skeleton. The Axial skeleton is found in the core of the body, these bones are in place to protect the vital organs. Starting from the head there are 29 bones in the head. There is 8 cranial bones and 14 facial bones.

Within the trabecular bones are lamellae called trabeculae. Trabeculae are arranged as rods or plates and contain blood vessels that deliver nutrients to osteocytes and remove waste. Between the trabeculae is red bone marrow, which forms blood

The bones are important components that provide support to the human body. Bones are composed of calcium, phosphorus and magnesium. Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissue. This leads to increased bone fragility and risk of fracture. Two essential cells are involved in the daily turnover of the bone, osteoblast cells and osteoclast cells.

A miniature model of the future bone develops in the fetus. A thin tubular bony collar forms around the middle of the cartilage model of the developing bone. This is an indication that endochondral ossification is about to start. Chondrocyte hypertrophy is in the centre of the cartilage model, chondrocytes increase in size and creates alkaline phosphatase, which is secreted into the extra- cellular matrix. Matrix calcification is the calcification of the cartilage matrix occurs around the enlarged chondrocytes, the chondrocytes die because nutrients are unable to diffuse through the calcification matrix.

Structure Of The Foot: The structure of the foot comprises 26 mostly small bones and 33 joints which form two arches. These bones are held together by the fact that they fit into each other; and fibrous ligaments, muscles and a tough tissue (known as the plantar fascia) support them to retain the shape of the foot. There are also fat pads in the foot, which assist in absorbing impact and with weight bearing. The two major functions of the feet are that act as levers which push the leg forward to enable us to walk; and they help in maintaining body balance by being able to adjust to uneven surfaces.

Our bones need the correct amount of vitamin D, which then results in the efficient amount of calcium in our bones. The other factor is staying active in our day to day. When we exercise our skeletal muscle pulls against the bone causing it to rebuild and become denser. 2. Describe the process of healing a fracture

2. One of the first guideline principles that you stated was that “cells form the foundation of body structure and function.” The first guideline principle would relate to the integumentary system as it consist of exocrine glands, skin, nails, and hair. Skin is one of the major organs not only in the integumentary system but also for our body. Our skin is made up of thousands of cells that serve a certain structure and function.

Most skeletal muscles are attached to bones by a bundle of collagen fibers. The Skeletal System is what helps the muscular system move with the muscles being attached to the bone allowing it to move the arms, legs, etc. It is the structure of the organism. There are several different types of skeletal systems

Typically, it happens when the bone was subjected to impact of more force or pressure than it can withstand. Commonly, broken bone can happen in childhood and mature and late adulthood. Children’s bones are still forming yet in mature and late adulthood, elderly becomes more likely to trip and fall. There are many types of fractures, but the major classes are simple fracture and compound fracture [1]. These fractures can be transverse

As seen in Figure 1, stem cells also have the potential to change into many different types of tissue in the body such as that of the ectoderm, mesoderm or endoderm. When a stem cell divides, it has the potential to stay a stem cell or it can differentiate to become a more specialized cell such as a red blood cell, intestinal cell or a

The nucleus contains the DNA, with genetic codes that helps to shape the inherited traits. The cytoplasm is like a workshop in the cell, where most functions occur. Mitochondria in the cell which provides energy from the conversion of food, which let the human body to function. They are tiny compartments found within cells and they perform lots of
