Bio 201 – Human Anatomy
Objective list for Nervous System
I.
II.
Exercise #15
a. Read and understand written material.
b. Understand different divisions/subdivisions of nervous system
c. Examine nervous tissue on microscope (slide #17 and Figure 15.3)
i. Identify neuron (soma, axon, dendrite) and be able to differentiate
between what is a neuron and what is a glial cell. Don’t need to try
to identify specific glial cells.
d. Recognize different neuron shapes (Figure 15.5)
Exercise #16
a. Read and understand written material relating to: meninges, ventricles
of the brain
i. Know and understand Figures 16.3 and 16.4
b. When studying the brain anatomy we will focus on the structural
anatomy of the brain as opposed to the functional anatomy of the
brain.
i. Know and understand Figures 16.7, 16.9, 16.10, 16.11.
