Organization of Nervous Tissue – Lab Report AssistantExercise 1: Histology of the Nervous System
Data Table 1. Microscopic Examination of Nervous Tissues
Insert the images from the nervous slide supplemental document, then add required labels by
hand. Once this lab report is complete, print out the document and place in your lab notebook
for submission at the end of the semester.
Slide Labeled Photograph Description
The gray matter is
composed of cell, bodies,
dendrites, glial cells,
capillaries, and
unmyelinated axons.
Spinal Cord, The white matter is white
Cross Section because of myelination
of axons.
Ependymal cells line the
central canal;
oligodendrocytes form
the myelin sheaths.
In the slide there is
Neuromuscular
present a neuron with

, Questions:
A) Describe the specific functions of the glial cells found in the white and gray matter on your
slide. How do they differ from what might be seen in the peripheral nervous system?
a. The specific functions of glial cells are supporting the neurons and holding them
in place. They also provide nutrients and oxygen to the neurons, provide an
immune function and insulate neurons with myelination. They differ from what
might be seen in peripheral nervous system by the fact they only form the myelin
sheaths in the peripheral nervous system.
B) What is the appearance of the axon at the terminal where it meets the muscle cells? How
does this structure aid in its function?
a. The axon branches at the end allowing for the signals to be reached In multiple
areas.
C) Describe the structure and function of dendrites. Could you see them on the microscope
slide of the spinal cord cross section? Why or why not?
a. Dendrites branch out allowing the neurons to receive information. No, because
it is hard to tell them apart from axons.
