Unformatted text preview: AP-1 Lab 10 Lab ReportNameSection: ___DL3_____________Lab Report: Exercise 10: Organization of Nervous TissuePurpose: During this lab we will focus on learning the structure and function of a multipolar neuron. We will learn to describe the structure and function of unipolar and bipolar neurons, as well as the functions of the various neuroglia and supporting cells. Finally, we will learn to identify the structures of a nerve and explain the significance of the connective tissues that surround nerves.Activity 1: Multipolar NeuronsObservations:A neuron, is an electrically excitable cell that processes and transmits information by electrical and chemical signaling, the latter via synapses, specialized connections with other cells.The ox spinal cord smear, show multipolar neuron cell bodies.1The teased myelinated nerve are peripheral nerve whose axons are surrounded by layers of Schwann cell membranes that form the myelin sheath; also called medullated nerves.QUESTIONS:A.What is the function of a neuron? The function of a neuron is to transmit a signal at a very fast rate. The function of the entire nervous system is to provide a system that allows for signals to be transmitted quickly from one specific location to another locations.B.What is the difference between a neuron and a nerve? A neuron is an individual cell of the nervous system. Neurons communicate with one another and other tissues through long processes that extend from their cell bodies. There are different names for these processes; some are called dendrites, others are called axons. Often it is fine to be vague and just call them fibers. Fibers of multiple neurons serving a similar function can come together and be wrapped up in a piece of connective tissue. These fibers and their surrounding connective tissue are called a nerve.C.What gives a multipolar neuron its name? Multipolar neurons have many fibres attached to the cell body. One fibre, the axon, is longer than the others and carries the electrical impulses away from the cell body. The other fibres, called dendrites, are shorter and carry impulses to the cell body....
