1. Explain tetanus in skeletal muscle. Can the cardiac muscle be tetanized? Why or Why not? 2. A 50 year old woman, Darvessa, suffers from asthma, and takes a drug which is a beta agonist. This drug relieves her symptoms by causing bronchodilation in her respiratory tract. However, after a couple of weeks she returns to her doctor complaining of palpitations. Using your knowledge of physiology can you explain her palpitations after the use of the drug beta agonist. 3. Dr. Williams Black has two patients admitted in his hospital with some form of weakness in their voluntary movements. Patient 1 complained of weakness in his right arm for two days. Patient 2 complained of difficulty in walking which has developed over the past six months. Based on these complaints he makes a diagnosis of an upper motor neuron lesion in patient 1 and a lower motor neuron in patient 2. What physical signs do you expect to see in these patients? 4. Three-years old Alejandro tripped over a box and hurt his left knee. He began to cry and called his mommy. His mother rushed to his side and pressed hard on his knee where he said hurt most. In a few seconds Andrew stopped crying. Using your knowledge of physiology identify the mechanism that was responsible to decrease Andrew's pain when his mother pressed on his knee. Where will the pain sensation be perceived in the cerebral cortex (left or right primary somatosensory cortex? 5. A 45-year old woman Kohana Kei, who had never needed to wear glasses, experienced difficulty reading a menu in a restaurant. Lately, she has also been experiencing difficulty in reading the newspaper. Her family physician, Dr. Miya Hiroki, told her that it was because of her age. What changes occur in the eye with age that causes far-sightedness? What changes occur in the eye during near vision?
