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. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab. Step 1: Relates to Lab Exercise 10/Activity 1, 3, and 4. Assignment 1: Write a brief description of the three slides (Neuron, Spinal Cord Smear and C.S of Myelinated Nerve Fibers) as though you were explaining it to someone who cannot see the slide. Neuron- There is a reddish rounded shape with lighter thin looking branches these are†¦show more content†¦The axons are slender processes of uniform diameter arising from the hillock. There is usually only one unbranched axon per neuron. Step 2: Define terms related to nervous tissue Click on the Loyola University/ Part 6: Nervous Tissue. For each of the following terms, find at least one example slide containing the term. Identify the slide by number and define the term in your own words. 1. Axon is a singular fiber that carries information away from the soma to the synaptic sites of other neurons. 2.Dendrite are the receptive region of the neuron. They conduct electrical impulses toward the cell body. 3. Axon Hillock is a cone shaped area on the side of the soma and is where the axon arise. 4. Soma is the control center of the neuron. 5.Nissl bodies are in the soma of the nucleus and are made up ofrough ER. 6. Axodendritic Synapse axons that connect the axon to the dendrite. 7. Myelin Sheath whitish fatty segmented sheath around most long axons. It protects the axon, electrically insulates fibers from one another , and increases the speed of nerve impulse transmition. 8. Muscle spindle are sensory receptors in the muscle. They can detect changes in muscle length and then communicate it to the central nervous system. 9. Pacinian Corpuscles connective tissue wrapped around a nerve ending located in the deep layers of skin. 10.Astrocyte most abundant, versatile, and highly branched glial cell. They support and brace neurons, anchor neuron toShow MoreRelatedBio 201 Lab 91515 Words   |  7 PagesAP- Bio 201 Lab Report:Nervous System Please fill out this report and submit it to the dropbox.
