Textbook Question
Chapter 15, Problem 2CSL
When you were younger, your parents may have told you to wait until 1 hour after you’ve eaten before you go swimming. Based on what you’ve learned about the ANS, can you hypothesize why swimming right after a meal may be problematic?

Which of the following is True and which of the following is false: 1) Psychoactive drugs rarely provoke a response by the area postrema due to their ability to cross the blood-brain barrier easily.
2) George weighs 200 lbs and Marcy weighs 120 lbs. Both are sadly opioid addicts. If they both inject the same amount of heroin, they will likely have similar experiences because the amount of blood you have is not related to your weight.
3) Drugs that are addictive always produce tolerance and withdrawal.
4) Symptoms of withdrawal are usually the opposite of the effects of the previously used drug.
5) Although their main effects occur in other neurochemical systems, both MDMA (Ecstasy) and cannabis distort the activity of dopamine, suggesting that these drugs have the potential to be addictive.
6) Opioids produce most of their effects by enhancing the release of a variety of neurochemicals from presynaptic axon terminals.
6) Dr. Baskin is studying the heritability of aggressiveness in…

Skin Respiratory airways Heartarrow_forward1.Which branch of the ANS innervates more organs? 2. The ____________________ of the motor neurons of the autonomic nervous system are located in the motor ganglia. 3. When norepinephrine is secreted from the postganglionic fibers of the sympathetic nervous system it will have an excitatory or inhibitory effect on the effector depending upon the type of norephrin receptor is present on the effector. True/False 4. The organs innervated by the autonomic nervous system may be inhibited or activated depending upon which division of the ANS is acting upon them and the type of receptor present on the target cells.

- Which part of the brain is the main integration center of the ANS? Which part exerts the most direct influence over autonomic functions?arrow_forwardFor each statement about the central nervous system, determine whether it is True or False. Commissural fibers in the brain False connect the right and left hemispheres. True Blockage of CSF drainage is much more dangerous in newborns than in adults. False A patient with damage to their left motor cortex will have trouble moving the left half of their body. Hemiplegia most often results from damage to the brain. True False Most medications and toxins injected into the bloodstream readily make their way into the cerebrospinal fluid. <arrow_forwardWatch this animation (http://openstaxcollege.org/l/CSFflow) that shows the flow of CSF through the brain and spinal cord, and how it originates from the ventricles and then spreads into the space within the meninges, where the fluids then move into the venous sinuses to return to the cardiovascular circulation. What are the structures that produce CSF and where are they found? How are the structures indicated in this animation?arrow_forward
- Paul ate a big lunch and then decided to jog a mile, which was not a very good idea. His digestive system was put “on hold” while his sympathetic nervous system was stimulated to run. Trace the sympathetic pathway from the lateral gray horn of the spinal cord to the stomach.1. Identify the nerve that the preganglionic axons form.2. Name the effector (the tissue within the organ that is innervated by the postganglionic neuron).Burke is in the final 100 yards of a race with an opponent at his heels. His sympathetic nervous system is stimulating his adrenal medullae. Trace the sympathetic pathway from the lateral gray horn of the spinal cord to the adrenal medulla.3. Name the sympathetic ganglia in which the preganglionic axons synapse.arrow_forwardWhich of the following is a feature exclusively of the sympathetic division of the ANS? Select one: O a. Postganglionic axons tend to be localized to a single effector O b. Most preganglionic axons are short O. None of these options is a feature of the sympathetic system O d.
