Lab Report: Exercise 10: Organization of Nervous Tissue
Purpose: What is the purpose of this exercise? Are there any safety concerns
associated with this exercise? If so, list what they are and what precautions
should be taken.
Activity 1: Multipolar Neurons
Sketch your observations through the microscope of the ox spinal cord smear, and the
teased myelinated nerve. Describe the cells and structures you observed.
A. What is the function of a neuron?
B. What is the difference between a neuron and a nerve?
C. What gives a multipolar neuron its name?
D. What are the functions of the dendrites and axons?
Activity 2: Structures of Selected Neurons
A. Which slide contained bipolar neurons?
B. Which slide contained unipolar neurons?
C. What was unique about the dorsal root ganglion compared to the other two slides?
Activity 3: The Neuroglia and Supporting Cells
Cell Function Location (CNS/PNS)
Support and brace neurons to nutrient
Provide protection and sense neuron
injuries. Can be phagocytic.
Ciliated cells found in the cavities of the
brain. Help to circulate cerebrospinal fluid.
Makes the myelin sheath in the central
Surround neuron cell bodies with ganglia.
Function is mostly unknown.
Produces the myelin sheath in the
peripheral nervous system
Activity 4: Structure of a Nerve
A. Describe the functions of the following parts of a nerve:
B. What is a nerve?
C. Why are the connective tissue wrappings an important part of nerve structure?
D. Differentiate the central nervous system from the peripheral nervous system.
Activity 5: Dissection and Identification of Nerves in the Cat
Compare the brachial plexus nerves in cats and humans.
What would be the consequences of an injury to the sacral plexus?
Describe the structure of nervous tissue and relate it to its function.
