Answer and explanation :
there are many problem due to lack of pneumotaxic and stetch receptor neurons on ventilation
DUE TO LACK OF PNEUMOTAXIC CENTER :
- pneumotaxic center is present in the nucleus which is used to transmit impulse to the inspiratory area which is not possible due to lack of pneumotaxic center
- it controls the duration of filling of lungs
- it also control the medullary respiratory system which is not possible due to lack of this
DUE TO LACK OF STRETCH RECEPTOR :
- The hearing breuer inflation reflex is generated by stretch receptor neuron which is not generated due to lack of stretch receptor
- when stretched these receptors send the inhibitory impulses through the vegus nerve to the DMG neuron which is not possible due to lack of this
Osteoporosis is a bone disorder that affects the structure of the bones and their hardness. The risk factor for Osteoporosis can be avoided by intaking a diet rich in calcium and vitamin D.
<h3>What is Osteoporosis?</h3>
Osteoporosis is the disease of the skeletal system that weakens the bones and makes them susceptible to breaking by becoming brittle. The bones in the diseases become very fragile that even a small stress condition can lead to bone fracture.
As one ages the level of calcium and vitamin D produced in the body gets depleted and as a result, the bones become weak and porous. The level of these elements must be balanced by the external food in the diet.
The nurse should provide information to the older adults on Osteoporosis by educating them on the dietary intakes that are rich in vitamin D and calcium. The intake of sodas must be reduced as they are rich in phosphorous that weakens the bones.
Therefore, dietary information must be given to the person to reduce the chances of Osteoporosis.
