Concept explainers
Peyton felt strange when she awoke one morning. She could not hold a pen in her right hand when trying to write an entry in her diary, and her muscles were noticeably weaker on the right side of her body. Additionally, her husband noticed that she was slurring her speech, so he took her to the emergency room. What does the ER physician suspect has occurred? Where in the brain might the physician suspect that abnormal activity or perhaps a lesion is located, and why?

- Mrs. Giammo asks, "How is what I had different from a stroke?" Provide a simple explanation of how a transient ischemic attack (TIA) differs from a cerebrovascular accident (CVA, stroke).arrow_forwardWhat causes the perceived left arm pain associated with a heart attack?arrow_forwardWhen I was lying on the ice, I could feel the cold ice on my left hip, but could not feel the my trainer's hands when she was pressing there. And then, when they turned me around, I could feel her touch on my right hip, but not the cold ice! How can that be? You tell him that his injury probably caused a lesion: A) On the left side of the medulla B) On the left spinal cord, between the medulla and the level of his hips C) On the right spinal cord, between the medulla and the somatosensory cortex D) On the left somatosensory cortexarrow_forward

To find sufficient time to study, hestayed up late and drank large amounts of coffee to stay alert.One evening during a very late study session, Huang felt apounding in his chest and thought he was having a heart attack.His roommate took Huang to the emergency room. After anexamination and interview by the physician, Huang was toldthat he probably had a cardiac arrhythmia. What was the mostprobable cause of the arrhythmia?arrow_forwardA 45-year-old woman comes to the physician because of a 3-month history of difficulty walking. Physical examination shows an erratic, reeling, imbalanced, and broad based gait. Attempted compensatory movements exaggerate her state of imbalance. A lesion or primary dysfunction in which of the following structures Is the most likely cause of the abnormal gait in this patient? A) Anterior columns of spinal cord B) Anterior horn cells C) Basal ganglion D) Parietal lobes E) Posterior columns of spinal cord F) Vermisarrow_forward
- A 50-year-old woman comes to the physician because of a 1-month history of shaking of her right arm when writing or lifting a cup. Physical examination showscoarse action tremor of the right upper extremity that worsens as she approaches the target. This patient most likely has damage to which of the following components of the brain?A) CerebellumB) Internal capsuleC) Substantia nigraD) Subthalamic nucleusE) Supplementary motor cortexarrow_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_forwarda 23 year old man is brought to the emergency department after being in a fight . examination shows a puncture wound in the occiput . one medullary pyramid is out immediately below the pons . which of the following is the most likely clinical finding.

He is nowa quadriplegic, meaning that both his upper and lower limbs areparalyzed.

He has also noted progressive difficulty walking, he lifts each foot high and stamps it forcefully on the ground with each step. He must watch his feet while walking to avoid striking doors or other obstacles with them. The disorder producing these symptoms most likely involves which of the following structures? A) Cerebellum B) Joints C) Muscles D) Motor cortex E) Posterior columnsarrow_forward
