Summary Introduction
To review:
The role of the autonomic nervous system in producing the symptoms of shock and the drugs used to treat the condition.
Introduction:
SThe shock is a condition where the body parts do not receive the a proper supply of oxygen-rich blood. The nervous system controls the functioning of the whole body. The nervous sytem has two main systems, namely the central nervous system (CNS) and the peripheral nervous system (PNS). The peripheral system is divided into the somatic nervous system and the autonomic nervous system.

- Abnormal softening of the nerves is called ________________________ .arrow_forwardWhich 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…arrow_forwardDraw a graph of the autonomic system and identify the neurotransmitters and receptors such as dopamine,norephinephrine and etc. and where it binds to alpha and beta. please explain as well.arrow_forward

- compare and contrast the differences between the sympathetic and parasympathetic nervous systems. Use the following scenarios: Scenario 1: You are walking outside late at night and you hear something in the bushes as you approach your home. Which system will dominate and what physiological changes will occur? Scenario 2: You have just finished a big dinner and now you are relaxing in your recliner to watch the big ball game. Which system will dominate and what physiological changes will occur? Be sure to at least include what happens to heart rate, blood pressure, and digestion. You may include other physiological variables as well. "Not a homework assignment"arrow_forwardReserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Epinephrine, norepinephrine, and dopamine are examples of catecholamine neurotransmitters. One of the known side effects of reserpine is to cause the symptoms of Parkinson’s disease. Parkinson's disease is associated with dopamine. Parkinson's disease occurs when the nerve cells in the part of the brain that controls muscle movement are gradually destroyed and the neurons can no longer produce dopamine to coordinate muscle movements. Reserpine causes symptoms by a. inhibiting the release of dopamine from the presynaptic neuron b. blocking the dopamine receptor in the postsynaptic neuron c. breaking down the neurotransmitter acetylcholine in the synapse d. breaking down cholinesterase enzyme in the synapsearrow_forwardRank the following in order from the most common in occurrence to the least common in occurrence.
