Stamp: The Nervous System 1. The image below is of a neuron, add the following labels to the image below Axon Myelin Sheath Cell Body Dendrites Axon Terminals Node of Ranvier Synaptic End Bulb Nucleus 2. There are three functional classifications of neurons. Match each type with the correct function. a. Sensory neuron b. Motor neuron c. Interneurons ________ The nerve cell that carriers impulses from a sense receptor to the brain and spinal cord. ________ The nerve cell that connects sensory and motor neurons. ________ The nerve cell that transmits impulses from the brain or spinal cord to a muscle or a gland. 3. There are three structural classifications of neurons. Go to http://www.rnpedia.com/home/notes/medical-surgical-nursing-notes/nervous-system find the classification of neurons sections, label each neuron below as multipolar, bipolar or unipolar and answer the questions. a) Which type of neuron would most likely be found in the inner ear? b) Which type of neuron would most likely be found in the brain? c) Which type of neuron would most likely be found in the olfactory area of the brain? d) Do you think there is a correlation between the amount of dendrites found in a neuron and the location of the neuron? Explain your answer. 4. Use your notes, what you learned during lecture and your book to match the correct description to the correct term. Synapse, Axon, Myelin Sheath, Enteric Plexuses, Nerve Impulse, Sense Receptor, Response, Reflex, Cell Body, Dendrite, Ganglia, Nerve, Neurotransmitter, Axon Terminal, nodes of ranvier a. b. c. d. e. f. g. h. i. j. k. l. m. n. o. ___________________ The long fiber that carries nerve impulses. ___________________ A bundle of axons. ___________________ The connection between adjacent neurons. ___________________ The chemical secreted into the gap between neurons at a synapse. ___________________ A rapid automatic response to a stimulus. ___________________ The covering of fatty material that speeds up the passage or nerve impulses. ___________________ The structure at the end of an axon that produces neurotransmitters to transmit the nerve impulse across the synapse. ___________________The high speed signals that pass along the axons of nerve cells. ___________________ The branching filaments that conduct nerve impulses towards the cell. ___________________ The sense organ or cells that receive stimuli from within and outside the body. ___________________ The reaction to a stimulus by a muscle or gland. ___________________ The part of the nerve cell containing the nucleus. ___________________ The masses of tissues which are located outside the brain and spinal cord. ___________________ The network of neurons which are located within the gastrointestinal tract. ___________________ Gaps in the myelin sheath. 5. What is the difference between myelinated and unmyelinated cells? 6. What roles do the axon and axon terminals play in the communication of one neuron with another? 7. Describe a Schwann Cell 8. Indicate whether the following parts of the nervous system are part of the Central Nervous System or the Peripheral Nervous System Brain: Spinal Cord: Autonomic Nervous System: Spinal Nerves: Cranial Nerves:
