- Describe the structure of the neuroeffector junction at which postganglionic autonomic neurons innervate their target organsWhich of the following is characteristic of parasympathetic ganglia the ganglia are formed of the cell bodies of general somatic efferent neurons O the ganglia are formed of the cell bodies of preganglionic neurons parasympathetic autonomic ganglia are ALL found within the walls of the effector glands or organs synapses between preganglionic and postganglionic neurons are formed within the autonomic gangliaThe cell bodies of autonomic postganglionic neurons are found in ANS ganglia. The cell bodies of another class of neuron are also found in ganglia (but not ANS ganglia). What are these other ganglia called? Determine the structural and functional classification of the neurons found in these other ganglia.
- There are 2 neurons in the ANS pathway – a preganglionic neuron and a postganglionic neuron. Describe each neuron (short or long) and what neurotransmitter is released from each neuron. Describe the neurons for each division of the ANS: (short description, NOT essay )Describe the general rules for neurotransmitters secreted by pre-and postganglionic neurons in the autonomic division of the nervous system. Be sure to identify them and specify the types of receptors each binds toname the neurotransmitters employed at differentsynapses of the ANS;
- Describe difference in location between sympathetic and parasympathetic ganglia. Describe difference in myelination between nerves of somatic and autonomic NS.Sympathetic and parasympathetic preganglionic fibers release the neurotransmitter:The ANS is subdivided into sympathetic and parasympathetic divisions.

- In the sympathetic division of the autonomic nervous system: Select one: The ratio between the number of postganglionic and preganglionic neurons is small. A single preganglionic neuron usually synapses with a single postganglionic neuron. An important functional characteristic is convergence of the preganglionic fibers. Preganglionic fibers are usually much longer than the postganglionic fibers. Activity of the neurons tends to have a more generalized and widespread effect on the body.Describe the basic differences between the parasympathetic and sympathetic divisions of the ANSThe thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex. Describe the organization of autonomic motor neurons. Describe the structure of the sympathetic and parasympathetic divisions of the autonomic system Distinguish between the different types of adrenergic receptors and state where these receptors are located in the body. Explain what is meant by nicotinic and muscarinic Acetylcholine receptors and describe where these receptors are located in the body. Explain the mechanisms involved when a person blushes. What structures are involved in this response? Analytical Question: Case Study: Princess Leia has asthma, and had to use her inhaler before taking her physiology exam.
