Summary Introduction
To determine:
The necessity of having an expensive mechanism of mass activation response of the sympathetic nervous system at disposal.
Concept introduction:
The sympathetic nervous system is most active when something exciting is going to happen. Mass activation of the sympathetic nervous system refers to the stimulation of various body structures through sympathetic neurons. Mass activation is often a response to a crisis.

- The fight-or-flight reaction prepares an animal to Pesponu Lu a threatening situation, by either fighting or running away. One aspect of this response is changes in blood flow such that the skeletal muscles and heart receive higher blood flow (vessels dilate) while digestive organs receive less (vessels constrict). A) Which signal molecule(s) is/are involved in this response, and how do they produce these changes in blood vessels? Briefly explain how this example illustrates how different cells are able to use the same ligands in different ways.arrow_forwardI am confused about the process of rod cells in the dark. In the dark, rod cells are unstimulated and therefore the sodium is able to enter and depolarize the cell, stimulating the release of glutamate to the bipolar cell. However, this increase in glutamate in the bipolar cell inhibits the release of action potential from the bipolar cell to the ganglion cell. This doesn't make sense to me because shouldn't there be an increase in action potential since the rod cells are supposed to function in the dark?arrow_forwardExplain the difference between slow and fast chemical transmission.

- Dopamine is a neurotransmitter produced by the nervous system that is involved in the pleasure/reward system in the brain. The release of dopamine in response to a stimulus produces feelings of happiness and satisfaction. Cocaine is a type of drug that affects the brain response to dopamine. Usually after dopamine is released into the synaptic cleft, it is quickly re-absorbed into the neuron using dopamine transporters. However, cocaine blocks these transporters which causes dopamine to remain in the synaptic cleft for a long period of time. How would this impact the neuron's ability to communicate? Neurons will produce smaller action potentials because more dopamine is binding to receptors on the neuron, preventing the neuron from reaching the threshold potential Neurons will be under-stimulated because dopamine will bind to receptors and prevent ions from moving into the neuron, preventing electrical signaling Neurons will produce larger action potentials because more dopamine is…arrow_forwardWhich of the following statements about the relationship between the nervous and endocrine systems is NOT correct? Hypothalamus controls a part of the endocrine system called the pituitary gland. Hypothalamus produces ADH Neurons of the sympathetic nervous system stimulate the production of hormones from the adrenal gland. None of these. Which refers to the time during which a neuron can undergo an action potential? the resting membrane potential the depolarization period of the neuron polarization period of the neuron O the membrane potentialarrow_forwardATPase is an enzyme that can hydrolyse ATP and release the potential energy stored in the phosphate bond. How would a metabolic inhibitor that blocks ATPase function affect the resting potential of nerve cells?arrow_forward
- A student is eating at the lab bench (a clear violation of lab policies) and mistakenly sprinkles tetrodotoxin on his fries. Explain the origin of the toxin and its normal function in that animal. Given that this substance inhibits voltage-gated sodium channels, indicate whether each of the statements below are true or false. Explain your answers. Explain the time course of the response. It will be more difficult for the student’s neurons to generate action potentials The student’s neurons will fire more frequently because membrane potential will be brough closer to threshold. The effect on the membrane potential o the student’s neurons could be predicted by the Nernst equation, which factors in the effects of both ion concentration and ion permeability.arrow_forwardAre these true or false? Acetylcholine molecules are actively transported from the axon to their receptors on the muscle membrane by special transport proteins. Receptors on the post-synaptic cell membrane that bind the acetylcholine are voltage-gated channels (channels that open in response to a change in the electrical charge of the membrane). When a muscle cell is not contracting its cell membrane is negative on the inner surface. The effect of a neurotransmitter on the muscle cell membrane is to modify its ion permeability properties temporarily. During depolarization, a small region of the muscle cell's membrane becomes less negative on the inside." Both sodium and potassium are more concentrated in the extracellular fluid than the intracellular fluid. After an action potential passes over a region of the sarcolemma the region remains positively charged throughout the entire muscle contraction. An increase in the calcium ion level in the cytosol causes thin filaments to begin…arrow_forwardSomeone goes for a jog first thing in the morning and encounters a squadron of javelinas, causing a release of epinephrine. Some of this circulating epinephrine binds to a G-alpha-s coupled receptor (GPCR) on the surface of muscle cells. Which of the following would occur in the muscle cell as a result of this activation? Nitric oxide synthesis would increase. cyclic AMP (cAMP) activity would increase. Phospholipase C (PLC) would hydrolyze (cut) the molecule PIP2. The levels of adenylate cyclase activity would decrease. The levels of adenylate cyclase activity would decrease. Which ligand is CORRECTLY matched with its characteristic? Group of answer choices Glucagon: stimulates the activation of the mitogen activated protein (MAP) kinase pathway Nitric oxide (NO): must bind to its target protien withn a few seconds because NO degrades rapidly Steroid hormone: produces a response in its target cells within seconds Acetylcholine: hydrophobic molecule that binds to…arrow_forward
- Clostridium botulinum is a bacteria that produces a toxin. The toxin is deadly to most animals, because it prevents vesicle movement inside the axons of motor neurons. If a person were to consume food contaminated with Clostridium botulinum, which of the following would most likely occur? flaccid paralysis because their motor neurons would not be able to conduct action potentials along their axons. spastic paralysis because their motor neurons would release too much acetylcholine at the synapse with a muscle fiber spastic paralysis because their motor neurons would conduct too many action potentials along their axons. flaccid paralysis because their motor neurons would not be able to release acetylcholine at the synapse with a muscle fiberarrow_forwardParkinson's Disease Parkinson's disease is neurodegenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. Describe the normal process of signal transmission at a synapse. Start with the arrival of an action potential at the axon terminal and include the name of the neurotransmitter that is affected by Parkinson's disease. Explain how the process is different in individuals affected with Parkinson's disease.arrow_forwardWith respect to nerve impulses, the Rising Phase is initiated by binding of neurotransmitters to ligand channels.
