Nervous System Lab – Week Seven
Introduction
The nervous system has two components: the central nervous
system, which consists of the brain and spinal chord; and the
peripheral nervous system, which is composed of nerves. As
you learn about the various diseases that affect the nervous
system, it is important for you to understand the structures that
can be affected by disease. Complete this lab to become familiar
with a healthy system and to identify diseases related to the
brain, spinal chord, and nerves.
PART ONE: basic functions
Provide brief answers to the following questions to help you get
acquainted with the basic functions of a healthy nervous system.
Refer to Ch. 24 in Microbiology: Principles and Explorations.
1. How do the meninges and cerebrospinal fluid (CSF) function
together in a healthy nervous system; what are their roles?
2. What is the blood-brain barrier?
3. What normal microflora reside in the nervous system?
PART two: basic structures
Visit Chapter 24 of Microbiology: Principles and Explorations
in WileyPlusto view an in-depth presentation of a healthy
nervous system by completing the following steps:
· Select the Chapter 24 WileyPlus reading link located on your

16. student Web page.
· Locate the heading Chapter Review.
· Select the Anatomy Overview: The Nervous System link.
· Complete this lab as you explore the Nervous System
multimedia piece.
Nervous System: The Brain
Roll over each component of the Nervous System multimedia
piece. Click on the brain. Refer to the Braincomponent of the
multimedia piece to label the structures in the following
diagram of a healthy brain.
Nervous System: The Spinal Cord
Click the icon in the upper left corner of the Brain diagram to
return to the main menu in the Nervous System multimedia
piece. Click the Spinal Cord component to navigate to the
Spinal Corddiagram. Refer to the Spinal Corddiagram of the
multimedia piece to label the following structures of a healthy
spinal cord.
PART three: investigate and apply
Several different pathogenic bacteria can cause bacterial
meningitis, an infection and inflammation of the meninges.
Select any form of bacterial meningitis discussed in Ch. 24 of
Microbiology: Principles and Explorations, and answer the
following:
1. Which form of bacterial meningitis did you select and what is
its causal agent?
2. What symptoms are typical of this form of meningitis?

17. 3. Which age group or population is most susceptible to this
form of meningitis and do typical activities within that age
group have any influence on a person contracting the disease?
