You are walking to class, pondering the intricacies of physiology, when you trip over an uneven place in the sidewalk and fall. Unhurt but embarrassed and angry, you jump up and glance around to see if anyone is watching. From your knowledge of neuroanatomy and function, explain how the following areas of the brain might be involved in this scenario:
cerebrum
cerebellum
limbic system
Explain why damage to peripheral nerve fibers is often reversible, whereas damage to CNS fibers rarely is.
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?

- Julio D., who had recently retired, was enjoying an afternoon of playing golf when suddenly he experienced a severe headache and dizziness. These symptoms were quickly followed by numbness and partial paralysis on the tipper right side of his body, accompanied by an inability to speak. After being rushed to the emergency room, Julio was diagnosed as having suffered a stroke. Given the observed neurological impairment, what areas of his brain were affected?arrow_forwardA patient had a stroke to their left internal capsule, an area of the brain where the corticospinal pathway passes through between the cortex and the brainstem. What would you expect to observe in this patient? Be specific with what side of the body would be impacted.arrow_forwardAfter a stroke, Shekina has difficulty holding a pencil in her left hand correctly and can't write her name, but she has no difficulty with her balance or body posture.

- Epilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures. About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain. A common goal of the surgical procedure to treat epileptic seizures is to reduce the connection between the two hemispheres of the brain. By cutting through this structure, an epileptic seizure occurring on one side of the brain will not be spread to the other side. Identify the structure that connects the two hemispheres of the brain.arrow_forwarddamage to the brain will always have lasting effects, but the timing of the damage is important. At what times of life is brain damage more or less likely to have significant long-term effects? Describe some of the ways in which the brain can recover function following brain damage.arrow_forwardShemia's father had a stroke in his early 50s, which initially impaired his ability to walk and use language.
