Skeletal System
1) As we age, our bones start to deteriorate because they lose their ability to regenerate as quickly as they had in the past. This leaves our bones less dense, and more brittle than healthy bones. What often results from this is fractured hips, and wrists from very light contact. The majority of the individuals that suffer from osteoporosis are women over the age of fifty. There is no known cure for osteoporosis, but there are prevention techniques. Our bones require calcium and vitamin D to help fill gaps in the porous bones of those suffering from osteoporosis. So in order to prevent the natural onset of osteoporosis doctors often recommend adding a medication loaded with these vitamins or a diet high in these vitamins. The two types of medications doctors often prescribe are medications that slow bone loss and strengthens remaining bones, and medication that generates new bone.
Several medications on the market that help impede bone loss like Fosamax, Actonel, and Boniva. These inhibit osteoclast-mediated bone re-absorption. This allows bones to strengthen and prevents the loss of potential bone strength. The other type of medication is comprised of mainly Forteo and few other drugs. These drugs contain synthetic forms of naturally occurring hormones that help regulate calcium metabolism.
2) Our bones contain two types of bone marrow that can be converted into each other. Humans begin their lives with all red bone marrow, then as they age, the marrow begins to transform into yellow bone marrow. Both types contain numerous capillaries and blood vessels, which allow for the rapid exchange of oxygen.
The yellow bone marrow acquires its name from the yellowish tint from the fats it contains. Since fat yields t...

...and leadership. However, the pituitary needs help in directing the other glands so the hypothalamus receives electrochemical signals and then passes them on to the pituitary gland. The pituitary gland then produces hormones to direct the remaining gland to react. However, not all organisms have this type of endocrine system.
Endocrine systems do not exist in invertebrates; instead, they have a neurosecretory system that serves the same function as a human. Take for example sponges, they have no endocrine glands, but they do have excretory glands that release hormones. These glands release waste material and biotoxins through the pores of the sponge. The chemicals that are expelled from the sponge help to prevent infections from microbes and help to deter predators. Lacking the sophistication of the human endocrine system, sponges can only produce a few hormones.
These two hormone helps to regulate the calcium levels in the body. These two hormones work together to control the two cells (osteoblasts and osteoclasts) which allows the body to maintain the calcium levels going in and out of the bones. The calcitonin is the hormone which stops the osteoclasts from occurring but stimulates the osteoblast which results in the calcium level decreasing and the other hormone parathyroid stops the osteoblasts but stimulates the osteoclasts which increases the level of
Osteoporosis is the loss of bone mass and deterioration of bone matrix resulting in brittle and fragile bones (Weber & Kelley, 2014). The rate of bone resorption is greater than the rate of bone formation, therefore, causing bones to become porous and under stress, can fracture (Drake, Clarke, & Lewiecki, 2015). Conditions that contribute to osteoporosis include poor nutrition, menopause, long-term use of glucocorticoid therapy, and hyperthyroidism are only a few conditions. These conditions all have several related factors that contribute to osteoporosis, breakdown of bone or prevention of bone remodeling. For instance, inadequate dietary intake of vitamin D and calcium can lead to osteoporosis because they are necessary for bone
The hormones produced from the endocrine system come from a wide range of different places. Among those responsible for hormone production are the glands and a few organs as well. The glands that are involved are the pituitary, thyroid, thymus, parathyroid, and adrenal. The organs, which also play a vital part, are the pancreas, gonads, kidneys, heart, and parts of the digestive tract. All these different glands or organs work together in the production of certain hormones. Those produced in one location will almost always have an effect on many other areas of the body, not just the surrounding tissues.
Osteoporosis is a condition, in which bones are weak from deterioration, loss of bone mass, and quality-bone strength. Osteoporosis usually triggers postmenopausal women (women who have not had their period for a whole year), or older men and women. Some risks both older men and women endure when experiencing Osteoporosis are decrease of calcium and bone fractures. These symptoms or effects can all be caused by weight loss, smoking, age, ethnicity, genetics, medications, bone structure, and certain diseases that can later on contribute to Osteoporosis, such as rheumatoid arthritis. Osteoporosis may be prevented by going to drug therapy to stop alcoholism and smoking, a sufficient amount of calcium intake, and exercising; such as jogging, walking,

Osteoporosis is a common problem worldwide. It affects people of all races and ages. Older people are particularly prone to the disease because the ageing process involves bone weakening,
More than 20 million people in the united states are affected by osteoporosis disease every year. Furthermore, Osteoporosis leads to about 1.5 million fractures in this country every year ("Celebrate World Osteoporosis Day, 2016). Osteoporosis is a common disease where people lose bone density faster than normal. This disease causes the bone to become weak and brittle which leads to fractures of the spine, hip, and wrist from a simple fall or even a sneeze or a cough. Osteoporosis usually does not have any symptoms and goes undetected until a fracture occurs. This silent disease can impact any gender, but it affects more women than men especially after menopause. Osteoporosis occurs when more
Abstract: Osteoporosis is a bone disorder that occurs in people with poor bone density. This disorder can cause secondary illnesses such a fragility fractures. There are many risk factors that can cause osteoporosis, and there are preventative measures that can be used in prolonging a person’s chances of developing osteoporosis in later adulthood life. Diagnosis is easily achievable.
If bones are never conditioned to repair themselves through ossification, brittle bone builds up, and the body can not rebuild the bone efficiently. Estrogen maintains bone density and as women lose it as they age, bones become less dense and more brittle (Essentials of Human Anatomy and Physiology, Marieb). Symptoms of osteoporosis include, back pain and spontaneous fractures; most commonly occurring in the hips. Osteoporosis has no known cure at the moment, but doctors are working to find ways to make the disease more
Osteoporosis comes from the latin word meaning “porous bone”. If you were to look closely at a bone you could see there are these small spaces on the bone which is good, now if you look at someone who suffers from osteoporosis you will see these spaces are much larger. As these spaces become larger it takes away from the strength and integrity of the bone making it grow weak and thin. Osteoporosis is most common in women over the age of 50 and gives them a higher risk of fractures and or breaks especially common in the hips. While we know osteoporosis comes from a number of things it can be broken down to age, the hormonal changes most commonly seen in menopause and a lower intake of Vitamin D and Calcium. Age is the unpreventable factor that doctors or you cannot change. Hormonal changes can be fixed with supplements or hormone therapy along with ones intake of Vitamin D and Calcium. Hormone therapy, estrogen alone or the combination of estrogen and progestin have been proven to prevent and aide in the treatment of osteoporosis in

The endocrine system is composed by a group of glands that secrete hormones for the secretion of a specific organ and the result of this cycle will contribute to of physiological and behavioral activities. The circulatory system makes a connection with the hormones secreted because it helps them to travel around the human body in a very short time. The endocrine glands that secrete the hormones that target specific hormones consist of the pituitary gland, thyroid gland, adrenal gland, pancreas, ovaries and testes. However, they are secondary organs part of the body system such as the kidney, liver, and heart. The kidney in particular secretes endocrine hormones such as renin and erythropoietin (EPO).
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.
...culatory system. Pituitary gland is a growth hormone that helps in mertabolism and develops reproductive organs. The thyroid controls metabolsim on the rate that the body breaks down food. Adrenal gland secretes many hormones including adrenaline which prepares the body to react in a stressful situation. The pancreas produces digestive enzymes and insulin. Ovaries produce ova and estrogen. Testes produce sperm cells and testosterone. To stay healthy you should get a regular medical check-up, eat a well-balanced diet, sleep at least 8 hours, and decrease stress in your life. Some problems are growth disorders, diabetes, and obesity. Puberty begins at different times for girls then boys. Girls start around ages 9-13 and boys are ages 10-15.
The Skeletal System, also known as the Skeleton make up a framework that support the body and protect the organs. The Skeleton consists of the bones and joints of the body. In the human body there is 300 bones at birth, these then fuse together to make 206 bones in a fully grown adult. The Skeleton is made up of two divisions: The axial and appendicular Skeleton.
