1) What are the advantages of the sympathetic postganglionic neuron using norepinephrine as a neurotransmitter to communicate with effector organs/tissues compared to the parasympathetic postganglionic neuron using acetylcholine to communicate with effector organs/tissues?

1. A neurotransmitter of the sympathetic division of the nervous system that increases the heart rate and constricts smooth muscle in blood vessels to raise blood pressure in the "fight or flight" response is called epinephrine. aldosterone. melatonin. prolactin. 2. The body's continuing immune response and defense against pathogens it has seen before is known as active immunity. passive immunity. immunoglobins. toxic immunity. 3. Anemia can be caused by a diet lacking in which nutritional substances? calcium and vitamin K...

QUESTION 22 A neuron receives two neurotransmitter signals in a row from a single neuron. Each causes a graded potential that would by itself be insufficient to trigger an action potential, but the combined effect of the two graded potentials is sufficient to trigger an AP. This is an example of: temporal summation spatial summation summed twitches graded potential synergy 1 points QUESTION 23 The resting membrane potential is negative because: there are more positively charged proteins in the...

The sympathetic nervous system uses epinephrine, or adrenaline, as a neurotransmitter and a hormone to exert its effects. These effects are often described as "fight or flight". Answer the following prompt: Epi-pens, which contain epinephrine, are used in people who are having severe allergic reactions. Specifically, these are used to improve breathing problems. Why do you think epinephrine helps in this case? What are two other effects an epi-pen may have as a side effect? Would injecting the epi-pen be more...

If a pre-synaptic neuron released a neurotransmitter onto a post-synaptic neuron and caused potassium (K+) channels to open, what effect would this have on the post-synaptic neuron? A. the post-synaptic neuron would likely generate an inhibitory post-synaptic potential (IPSP) B. the post-synaptic neuron would likely generate an excitatory post-synaptic potential C. the post-synaptic neuron would likely release a neurotransmitter D. the post-synaptic neuron would likely produce an action potential

Messages are transmitted from one neuron to another via the synapse process. Define neurotransmitter, the four main categories, and their role in cell communication. Discuss one of the following synapse types: excitatory cholinergic, inhibitory GABA-ergic, or excitatory adrenergic.
