The sympathetic division is not found inside visceral organs, while the parasympathetic is.

What is the primary importance of reflex pathways? To limit the amount of damage caused by a harmful stimulus. They allow an organism to remove a potentially harmful stimulus as quickly as possible. They allow for maximal interpretation of a stimulus and response. None of the above. Only A and B. All of the above.

Which is an accurate difference between graded and action potentials? Action potentials lead to graded potentials. Action potentials are short distance, while graded potentials are long distance. Graded potentials vary in size, but action potentials are always the same size. All are accurate differences.

Dynamic antagonism describes how: the sympathetic and parasympathetic nervous divisions work together at times. the sympathetic and parasympathetic nervous divisions have opposing effects when each is activated. the sympathetic division tends to be stronger than the parasympathetic division the majority of organs in the body receive nervous signals from sympathetic and parasympathetic nervous divisions. none of the above

Multimodal association areas are so important to everyday life because: The receive multiple motor outputs to create the most well-rounded response. They receive multiple sensory inputs and interpret them to generate an overall understanding of the situation. They incorporate the sensory response into the motor response. All of the above are importances.

When smelling the faint smell of cooking gas in the night, you become increasingly aware and frightened. This represents how: olfactory receptors are connected to the limbic system and hypothalamus. olfactory receptors are connected to the reticular activating system and hypothalamus.olfaction has a very low threshold. all of the above.

Why will you have a greater reaction to having cold water poured all over your back compared to just a few drops of cold water on your arm? Pouring water stimulates more sensory neurons than a few drops of water. Cold water on the back stimulates a heightened response because it is further away from normal body temperature. More sensory neurons exist in your arms than in your back because the arms are exposed more to the environment. Cold water poured down your back will initiate a sympathetic response and, therefore, all reactions will be greater.

A person's taste preferences are influenced by genetic and environmental factors. Which is a true statement? New foods are more likely to be accepted when combined with familiar foods. The innate reaction to sour and bitter is disgust and a negative perception. O Through careful tasting and waiting for a bad experience, new food preferences are acquired. Positive and negative situations often determine the preference for certain foods. All are important in determining taste preferences.

Predict what would happen if a patient suffers from hyponatremia (low blood Na+). Lack of negative feedback control would cause a reduction in axon length. The action potential would not form properly -- the peak would be too low. There would be an increased rate of neurotransmitter release at the synaptic cleft. Muscles would be more easily contracted.
