Lab Report:Nervous System
Please fill out this report and submit it to the dropbox. Do not hand in your own form. It will not be graded and you will receive a zero for the lab.
You must get all parts correct to get credit for the question
* Please note that although you do not hand in items in observations, it is very important to do these as you may see some of these items on future/associated lab quizzes or be asked about some of these concepts on unit assignments.
Step 1: Nervous Slides
Assignment 1:
1. What are the sensory components of this structure? What are the motor components of this structure?
2. What does “Nb” represent and what is the function of this structure?
3. What is the function of this tissue? Name one disease that affects this tissue.
Activity 1: Multipolar Neurons
Observations: (No submission)
Sketch your observations through the microscope of the neuron, the ox spinal cord smear, and the teased myelinated nerve.
Answer these Questions:
A. What is the functional difference between a neuron and a nerve? A neuron is a nerve cell and is a basic building block of the nervous system. Neurons also have special functions, like transmitting information throughout the body. A nerve is a bundle of neuron cells.
B. What gives a multipolar neuron its name? A multipolar neuron contains several short and highly branched processes known as dendrites and that’s what gives it the name.
C. What are the functions of the dendrites and axons? The dendrites receive signals from other neurons cells, and axons transmit these signals within our bodies.
Activity 2: Structures of Selected Neurons ( NO SUBMISSION)
Activity 3: The Neuroglia and Supporting Cells
Please fill in the cell corresponding with the description: .5 pts.
1. Support and brace neurons to nutrient blood capillaries:
Astrocytes.
2. Provide protection and sense neuron injuries. Can be phagocytic.
