Textbook Question
Chapter 15, Problem 15RQ
The students in anatomy class were having difficulty understanding what kind of cell bodies are located. in the autonomic ganglia. Frustrated by being asked. this same question repeatedly, the exasperated teaching assistant stood on a desk and yelled, "Autonomic ganglia always contain the postganglionic cell bodies!� Describe how that information enabled the students to work out which type of neuron has cell bodies in the (a) sympathetic trunk ganglia, (b) intramural ganglia, and (c) head ganglia (ciliary, pterygopalatine, submandibular, and. otic).

A bit confused about this question I placed my answer below the question but not sure if the brain is synonymous or not with the peripheral nervous system due to the wording of the question.
In the background section the authors wrote “Neurodegenerative disease are progressive conditions that occur through impairment in the function or structure of neurons in the peripheral nervous system or brain [1].’ Based on this quote, is the “or brain” statement synonymous with the peripheral nervous system or is the “or brain” statement in addition to the peripheral nervous system?
The nerves outside of the brain and spinal cord are part of the peripheral nervous system. The main function of the peripheral nervous system is to transmit signals from the brain and spinal cord to the rest of the body making the "or brain" statement synonymous.
How do you know that your answer to question 1 is correct?
For each of the following terms or phrases, write either S (for sympathetic) or P (for parasympathetic) division of the autonomic nervous system.__(1) short preganglionic axons, long postganglionic axons__(2) intramural ganglia__(3) craniosacral outflow __(4) adrenergic fibers __(5) cervical ganglia of the sympathetic trunk __(6) otic and ciliary ganglia __(7) more widespread response __(8) increases heart rate, respiratory rate, and blood pressure __(9) increases motility of stomach and secretion of lacrimal and salivary glands __(10) innervates blood vessels __(11) most active when you are lolling in a hammock __(12) most active when you are running in the Boston Marathon __(13) gray rami communicantes __(14) synapse in celiac ganglion __(15) relates to fear response induced by the amygdaloid body
A) The neuron labelled "D" in the figure is what class of functional neuron?: 3rd-order? lower motor neurone? upper motor neurone? 2nd-order? bipolar? unipolar?
B) The message in the pleural pathway in figure 3 comes from the: occipital lobe? skeletal muscle? somatosensoty cortex? temporal lobe? receptors? parietal lobe? frontal lobe?
C) Damage to this structure in the figure would affect the ability to move your RIGHT leg: A, B, C, D, E, F, G
