OSTEOPOROSIS (BONE PHYSIOLOGY) Your great Aunt Flora fell and fractured her hip. The doctors said that her hip fracture was between the head of the femur and the greater trochanter-a very common fracture for a 72-year old woman. When you visited you great aunt in the hospital, the doctor told you that she had a severe case of osteoporosis, which probably resulted in the broken hip from the fall. Aunt Flora received a total hip replacement and was up in less than a week. 1. Which mineral supplements should Aunt Flora add to her diet? The doctor is concerned that a hormone deficiency may be contributing to the osteoporosis 2. a. What hormones would you expect to be low in your great aunt? b. How do these hormones affect osteoblast and osteoclasts? c. What do osteoblasts and osteoclast do in your bones? d. Describe how this hormone deficiency would affect bone density in terms of osteoblasts and osteoclasts. 3. What type of fracture did Aunt Flora experience?Explanation / Answer
She should add calcium to her diet.
As she is an elder person near to menopause,the decrease in estrogen level causes osteoporosis.
Low estrogen causes enhanced activity of osteoclast causing increased bone resorption.
Normally osteoblasts deposit bone and Osteoclast is involved in bone resorption.
Estrogen deficiency causes decreased bone density due to increased resorptive activity and normal osteoblastic activity.
She experienced a pathological fracture.
High impact weight bearing exercises like dancing,jogging should be suggested.
Bone should be subjected to stress to maintain its strength.In space as there is no gravity,the bones are not subjected to much stress causing decreased bone mass - osteoporosis
Osteoblasts deposit new bone and Osteoclast dispose older bone.thus these two cell maintain homeostasis in the bone.
If the osteoblasts are hyperactive,the bones become enlarged which is called Pagets disese
