Meningitis is an inflammation of the membranes that cover the brain and spinal cord. Diagnosis involves making a “spinal tap” (lumbar puncture) and analyzing a sample of cerebrospinal fluid for signs of infection. Why analyze this fluid and not blood?
In the examination of the cerebrospinal fluid, how to differentiate between subarachnoid hemorrhage and puncture accident? Explain in detail which parameters are to be analyzed.
Find a patient case similar to H.M. patient which helped the scientists to understand the function of a particular brain region. Explain the case.

The primary difference between spinal and epidural anesthesia is the site of a ministration of the anesthetic agent. The position of the patient and the skin injection site are similar. With spinal anesthesia, the medication injected directly into the cerebrospinal fluid (CSF) in the subarachnoid space between the meningeal layers of the spinal cord. With epidural anesthesia, the medication is injected into the tissues directly above the dura mater, where are the agent is then absorbed into the CSF.arrow_forward

Disseminated Focal Diffuse O Polararrow_forwardPlease describe an example of both a primary and secondary spinal cord injury. Our discussion this week pertains to Spinal Cord Injuries. Primary spinal cord injury involves damage to vertebral or neural tissues from compression, traction, or shearing forces. Secondary spinal cord injury is related to ischemia, excitotoxicity, inflammation, edema, oxidative damage, and activation of necrotic and apoptotic cell death; it begins within minutes after injury and continues for weeks. Assignment Instructions: Describe an injury. Some learners will use the same injury, such as a fall off of a horse. Describe how the patient experienced both primary and secondary injuries. Be sure to describe symptoms, implications, and testing that helped clinicians to classify the injury into these categories.arrow_forwardThe stage of spinal shock is characterized by the following except:-a- failure of spinal reflexes below the level of the lesionb- loss of sensations from the body below the level of the lesionc- loss of voluntary movement from the body below the level of the lesiond- exaggerated tendon jerks below the level of the lesionarrow_forward

The teachers often find her staring off into space when they try to get her attention. When Honey's parents mentioned this to their family physician, the possibility of epilepsy was brought up by the physician.arrow_forwardWhat components of the nervous system are directly affected by meningitis?arrow_forward
