Calcitonin

medications such as hormone replacement therapy to females hoping to increase the estrogen level in her body. They could also take either Alendronate or Calcitonin which are both drugs that stop the loss of bone, help rebuild the bone and help lessen the risk of a fracture significantly. Alendronate protects the bones from the osteoclasts while calcitonin also helps protect the bone by slowing down the osteoclasts cells. Osteoclasts cells destroy old bone tissue. Having a healthy diet that is…

Mechanism accelerates output created by a activated stimulus. Here are some examples of homeostasis mechanisms:- 1) Regulation of the blood calcium level- If the calcium level is high in blood it causes the secretion of a polypeptide hormone called calcitonin from the thyroid…

Thyroid Imbalances I chose this article to summarize because I am very interested in thyroid imbalances as I was tested for Hypothyroidism. This article helped me in understanding more about why the thyroid hormones do in the body and the signs and symptoms of each condition. Hyperthyroidism is an overstimulation of the sympathetic nervous system and metabolic rate. Hypothyroidism is an autoimmune disorder, which is caused from a decrease in metabolic rate and causes edema. While caring for a…

Chelsea Hornyak MED 2047 Osteoporosis Instructor Michelle Earixson-Lamonthe 2/28/15 VNFT031 Osteoporosis is a disease of the bones. The word osteoporosis means “porous bone.” It is a metabolic bone disorder which means that the rate of bone breakdown, which is called resorption, speeds up while the rate of bone formation slows down causing a loss of bone mass. In other words, osteoporosis happens when you lose too much bone, make too little bone, or even both. As a result…

calcitriol is located within the kidneys; this is where calcium absorption and phosphate reabsorption is amplified. Calcitriol is activated by the stimulation action of osteoblast that allows the amount of bone building to take place. Lastly, the hormone calcitonin opposes the function of the parathyroid hormone, however has a small part in the growth and remodeling of bone. It acts as an inhibitor of osteoclasts preventing erosion of the bone (NCBI,…

There are various theories exist regarding the mechanisms of origin of migraine headache. One of such theories is the vascular theory which proposes that the intracranial vasoconstriction causes ischemia, which results in the aura preceding the migraine. The subsequent rebound vasodilation causes the migraine headache. The theory was based on the observation that during a migraine attack the extracranial vessels become pulsatile and distended. However, this theory was disputed as it couldn’t…

Increased levels of thyroid hormones would A) decrease basal metabolic rate. B) up regulate beta receptors C) impair body growth. D) decrease the effects of norepinephrine on the heart and blood vessels. E) decrease protein synthesis. ____ 67. Calcitonin A) is synthesized by the parathyroid glands. B) acts primarily on osteoblasts. C) decreases blood Ca2+ levels. D) acts synergistically with calcitriol. E) acts permissively with PTH. ____ 68. The parathyroid glands A) are embedded within the…

Thus, the feces contain unabsorbed dietary calcium and unreabsorbed digestive juice calcium. The metabolism of calcium and phosphorus is closely related and influenced by parathyroid hormone (PTH), vitamin D, and, to a lesser extent, calcitonin. Bone remodeling of calcium and phosphorus integrates for four systems. The gastrointestinal system of endocrine system marked by parathyroid hormone (PTH) and vitamin D the renal system where vitamin D is activated and where calcium and phosphorus…

decrease and he will have greater levels of calcium in the blood. The administration of calcitonin and Vitamin D with calcium supplementation could aid in balancing blood calcium levels and loss of bone density. Vitamin D turns into calcitriol (the variant of Vitamin D) and this calcitriol binds to the PTh in order to help with breaking down the bone and releasing more calcium into the blood. Also, calcitonin will inhibit the osteoclast activity and increase the loss of calcium in urine through…

When bones and muscles connect a joint is formed. At this point both are joined together by the help of tendons, which is a connective tissue. When we have to move a joint the muscle receives an electrical signal from brain. It causes movement to occur, because this causes the contraction in it. This contraction pulls on the corresponding bone at its insertion point. Stationary bone is called the point of origin for the skeletal muscle, while the one which moves is known as the point of…
