It had been a busy week for Amanda. She had taken three exams, and as if that wasn't stressful enough, her sister was ill and Amanda had to spend much of her time helping out at home. By the end of the week, Amanda decided to go to the beach for a walk and some genuine relaxation. The day was warm and Amanda took off her shoes so she could walk barefoot and feel the sand between her toes. Halfway down the beach, she stepped on something extremely sharp and withdrew her foot in pain. As Amanda hopped around the sand on one foot, rubbing the other to ease the pain, she decided to put her shoes back on.
What type of reflex is responsible for the uninjured leg going into full extension so she can balance on one foot?

- Explain why the spinal cord is larger at C3-T1 and T9-T12.arrow_forwardMr. Q, age 64 years, developed a severe headache several hours ago that has not responded to acetaminophen (Tylenol). Now his speech is slurred, and his right arm and the right side of his face feel numb. He is very anxious and is transported to the hospital. Mr. Q has a history of smoking and arteriosclerosis, and there is a family history of CVA(Cerebrovascular Accident) and diabetes. Assessment at the hospital indicated weakness on the right side, including facial asymmetry and blood pressure of 220/110 Hg mm. A CT scan showed damaged tissue on the left side of the brain, and an angiography indicated a narrowing of the carotid arteries and middle cerebral arteries, with occlusion of the left middle cerebral artery. Explain the predisposing factors in this case, and relate Mr. Q’s initial signs to the pathological changes. Discuss the different types of disabilities That Mr.Q will face and possible treatments plans?arrow_forwardUnit Discussion Autonomic Nervous System Alain Lefevre is a 22 years old male with a history of Asthma, who plays football as a striker in a regional league.

The coach noticed it and took him to the nearby hospital. 1. What is the diagnosis? 2. Pathophysiology of this disease 3. What division of the nervous system is responsible of the manifestation of these symptoms? 4. Which type of cholinergic or adrenergic receptors will be targeted during the treatment of this condition? 5. Which type of drug would be mainly used to relieve this patient? Why?arrow_forward
- Meet Mr. Bergen Mr. Bergen, a 72-year-old man, is admitted to the hospital due to an acute onset of a right facial droop, right arm weakness, and difficulty speaking coherently. His symptoms started 6 hours prior while sitting at his kitchen table. He had no headache, loss of consciousness, and no abnormal motor movements. His medical history includes high blood pressure and a heart attack five years ago. His medications include a daily aspirin, and he has been a lifelong smoker. His temperature is normal, his heart rate is 62 beats per minute, and his blood pressure is 135/87. The rest of his neurological and physical exam is normal his heart rhythm is normal, and his blood tests all come back normal.
