Chapter 15, Problem 2DCR
Summary Introduction
To determine:
The anatomic structures that prevent the drug from reaching the brain and the mechanism by which these structures are helpful to an individual under different circumstances.
Introduction:
The brain is protected and isolated by multiple structures. These structures include the bony skull, meninges, cerebrospinal fluid (CSF), and the blood-brain barrier. The bony skull provides rigid support. Meninges are protective connective tissue membranes that surround, support, stabilize, and partition portions of the brain. CSF acts as a cushioning fluid.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
