Case 1

A 7-year-old boy has a 2-day history of severe headache, nausea, fever, and photophobia. He appears lethargic and ill. His temperature is 40^oC, and he has some nuchal rigidity. The most likely diagnosis in this case is bacterial meningitis.

In order to find the causative agent, a lumbar puncture is requested by the physician. Laboratory analysis confirms bacterial growth in the cerebrospinal fluid (CSF). Appropriate antibiotic therapy is administered and the patient recovers without any complications.

1. Where along the vertebral column is the needle typically inserted in order to perform a lumbar puncture? Provide an anatomical explanation for your answer.  

2. Explain why the needle is inserted in the median plane.

3. Following the procedure, the patient complains of a severe headache. Explain the possible causes for this complication.

4. Identify the most common causative organisms of meningitis.

5. Explain the various anatomical pathways of the bacteria from the external environment to the CSF inside the brain ventricles.  

6. Outline two reasons for the boy’s nausea, and photophobia.

7. Explain the structures, site of production and pattern of circulation of CSF throughout the brain.

1. Compare the anatomy of the dorsal column system and the anterolateral system and the way that information in each system reaches the cortex. What types of sensation does each carry? Where are the primary afferent neurons located? Where are the tracts and what are they called? Where are the synapses? In what area of cortex do the projections terminate? Are they crossed or uncrossed?

2. somatic motor column, and describe the nuclei found in that column. Specify the cranial nerves that they are connected to, the names and locations of the nuclei within the brainstem, and the function of the nuclei.

3. describe its organization the organization of the olfactory system. What are the receptors? What nerve or nerves carry information to the CNS and where does it (or they) terminate? What areas of the thalamus and cortex are involved?

At a minimum, select three named arteries and provide the following for each: - A locational description using proper regional AND directional terminology - The course of the artery, the tissues supplied by it, and any anatomical landmarks that are associated with your selected artery (e.g. – The left subclavian artery arises from the arch of the aorta, and passes laterally inferior to the clavicle before passing the first rib. It has multiple branches including the vertebral artery, the interior thoracic artery, the thyrocervical trunk, the costocervical trunk, and the dorsal scapular artery.

Branches of the subclavian artery supply the cerebellum and brainstem and muscles of the cervical and scapular regions.) Your structure exploration should be submitted as a separate document (in either PDF or Word form), containing properly cited references (in APA format).
