Bone physiology is the normal process of the bone to continuously breakdown and remodels themselves. The bone remodeling cycle begins when the osteocytes determine which part of the bone needs to be remodeled and send out signals to osteoclasts to reabsorb the bone. Along with the osteoclasts, the osteoblasts follow behind osteoclasts forming new bone reshaping as it goes in order to accommodate the current stresses on the body. The two types of bone tissue are the spongy bones and the compact bones. The compact bones support the whole body and are the outer part of the bone, whereas the spongy bones are located inside of the compact bone and are used to support the body structure. Calcium is stored in compact bone in high quantities, but very little is stored in the spongy bone.
2. The relationship between calcium and bones is that calcium is one of the minerals that make up the bones. During remodeling of bones, old calcium is removed from the bone and replaced with the new calcium that is in the blood stream. When an individual’s diet is not rich in calcium, the amount of calcium in the bone decreases over time and can lead to a weakening of the bones such as osteoporosis. Ideally, the individual should have eaten a diet rich in calcium during childhood and adolescents to make sure the bones have enough calcium to keep them strong for years.
3. The body controls calcium levels in the bones and blood by using the parathyroid hormone and calcitonin. When there is a low level of calcium in the blood, the parathyroid gland releases the parathyroid hormone (PTH) which targets the bones to stimulate the osteoclasts to reabsorb calcium out of the bones and release it into the bloodstream, the kidneys are stimulated to take in more c...

...e, Crohns’ disease, early onset menopause, removal of the ovaries pre-menopause, low testosterone levels in men. Anorexia during adolescent years is another risk factor as the individual will severely limit their diet and may not get enough calcium in what they do eat. Other individuals who eat a diet low in calcium and Vitamin D are also at risk. Another risk factor is gastrointestinal surgery that reduces the amount of surface that absorbs nutrients including calcium.
7. There are not definite signs or telltale symptoms of osteoporosis during the early stages. Osteoporosis is known as a silent disease because an individual may not know they have it until they fracture a bone. Once the disease has progressed, the individual may develop symptoms such as low back pain, loss of height over time, a stooped posture or a bone fracture that occurs more easier than normal.

Essay on Osteoporosis : A Skeletal Condition

- Osteoporosis, or "porous bones", is a skeletal condition characterized by low bone mass and microarchitectural deterioration of bone tissue.1 It can lead to bone fragility and an increase in falls and fractures. Decreased bone mass in osteoporosis is classified into primary and secondary groups with primary osteoporosis further divided into Type 1 and Type 2. Type 2 refers to postmenopausal osteoporosis which usually occurs 3 to 6 years after reaching menopause. Postmenopausal osteoporosis affects approximately 10 million people in the United States, and 80% of the affected population are women 50 years of age and older....   [tags: Osteoporosis, Bone, Osteoclast, Estrogen]

A Semi Mechanistic Bone Remodeling Theory Essay

- 2.1 A semi-mechanistic bone remodeling theory As opposed to soft biological tissues, which can experience both appositional and interstitial growth, hard biological tissue can experience just appositional growth because of the nonexpendable nature of the bone matrix [16, 17, 2829]. The proposed regulatory process of spongy bone remodeling, as proposed by Huiskes et al. [1920], can be seen in Fig. 1. Bone remodeling is depicted as a coupled process of bone resorption and bone formation on the bone free surface....   [tags: Bone, Skeletal system, Osseous tissue]

Description Of Bones And Osteoporosis Essay example

- Introduction to Bones and Osteoporosis Imagine not having any bones. You could be an immobile piece of flesh that is vulnerable to injuries. Bones are important organs in our bodies. Bones are rigid organs that protect other organs, give structure, aid in movement, produce red and white blood cells, support the body, and store vital minerals. The gross anatomy of a bone is compact and spongy bone. Compact bone is the smooth, dense outer layer of a bone and spongy bone (trabecular bone) is the inner portion of the bone that looks a bit porous like a sponge and between the spaces are red and yellow bone marrow....   [tags: Bone, Osteoporosis, Bone marrow, Skeletal system]

Bone Tissue In The Skeletal System Essay

- Bone tissue is the subject of Chapter 7. It covers the tissue and organs of the skeletal system, the histology of osseous (bone) tissue, the development of bone, physiology of osseous tissue and disorders of the bone. The skeletal system provides support to the internal structures of the body. It allows us to sit, stand, walk and even talk. It provides protection for such vital organs as the brain, heart and lungs, the marrow of bone produces new blood cells, and it aids the body in balancing acid and electrolytes....   [tags: Bone, Skeletal system, Bone marrow, Osteoblast]

Osteoporosis Is A Bone Disease Defined By Decreasing Bone Mass Essay

- Osteoporosis is a bone disease defined by decreasing bone mass resulting in minimal mechanical bone strength causing the patient to be at high risks of falls and fractures. The risk of bone fractures is base on bone strength and the forces applied upon it. However the severity of the disease can even cause bones to fracture with just minimal trauma from performing daily routines. Genetics, hormonal, and dietary factors are known to influence the onset of osteoporosis and its severity. There are two types of osteoporosis; Primary osteoporosis which results from old age or menopause and secondary osteoporosis defined as the loss of bone mass due to other disorders such as hyperthyroidism (Gra...   [tags: Osteoporosis, Bone, Skeletal system, Estrogen]

The Effects Of Long Bone Stress Fractures Essay

- The purpose of this paper is to provide a brief insight into lower extremity and in particular, long bone stress fractures. A stress fracture or hairline fracture is a fracture of the bone resulting from frequent or repetitive submaximal skeletal loading or inadvertent overuse of a particular bone. Stress fractures usually become apparent when repetitive stress applied to a bone is greater than the capacity of the bone to adapt to the repeated strain or force exerted on it (Pepper et al. 2006 p.4)....   [tags: Bone, Skeletal system, Bone fracture, Osteoporosis]

A Research Study On Metastatic Bone Disease And Treatment Of Bone Diseases

- Introduction Bisphosphonates are widely applied across the world in metastatic bone disease and treatment of bone diseases such as osteoporosis and Paget 's disease. They are classified as an anti-resorbitive drug, which defines that they slow/stop the natural processes which dissolve the bone tissue. The main impact of the drug, is to reduce the osteoclastic activity and to act upon the suppression of bone remodelling, thereby decreasing the destructive effects which accompany bone disease. Understanding the role in which bisphosphonates plays in the remodelling of bone is key to understanding whether it has a potential impact in a medico-legal setting....   [tags: Bone, Skeletal system, Osteoporosis]
