Chapter 32.2, Problem 2CC
Summary Introduction
To explain:
How would shortening the stimulus duration affect the need for negative feedback if a hormone pathway provides a transient response to a stimulus.
Introduction:
The organs of endocrine system release chemical signal as hormones. A hormone is released by the organ system when it receives an internal stimulus. The glands of endocrine system release their content directly into the blood circulation and regulate other organs of the body. They have no ducts and are called as ductless glands.
The hormones of endocrine system is responsible for the regulation of body

Why does TTX reduce the response caused by nerve stimulation and also the response to direct muscle stimulation?
Q4.7. Why does Na* enter the cell during the action potential?
Because the Na* channels are open and only let Na* move from outside to inside
Because the action potential pulls positive ions into the cell while Na* and K* channels are open
Because Na channels are open and allow Na* ions to move down the length of the axon to
produce neurotransmitter at the axon terminal
Because Na" channels are open and there is a higher concentration of Na outside of the neuron
than inside

- Q4.5. Why do neurons generate an action potential, instead of simply relying on the opening of ion channels near the stimulus site to transmit information? Because without the action potential, changes in Vm at the stimulus site might not reach the axon terminal Because without the action potential, the neuron would not depolarize Because action potentials help the body keep ion concentrations at appropriate levels Because without the action potential, the neuron would not return to resting potential O Oarrow_forwardQ5.5. Why do neurons generate an action potential, instead of simply relying on the opening of ion channels near the stimulus site to transmit information? Because, without the action potential, changes in Vm at the stimulus site might not reach the axon terminal Because without the action potential, the neuron would not depolarize Because action potentials help the body keep ion concentrations at appropriate levels Because, without the action potential, the neuron would not return to resting potential Submitarrow_forwardPractice 56 Which statement is true? The intensity of a stimulus is encoded by the adaptation of the action potentials. The intensity of a stimulus is encoded by the amplitude of the action potentials. The intensity of a stimulus is encoded by the duration of the action potentials. The intensity of a stimulus is encoded by the frequency of the action potentials.arrow_forward
- Q5.6. If calcium ions, each of which has a charge of +2 (Ca²+), moved INTO a neuron, and no other ions were moving, what would be TRUE? The area outside the neuron would be become more positively charged. The concentration of Ca²+ inside the cell would decrease. The neuron would become more negative. The neuron would become more positive. Submitarrow_forwardQ4.4. Which statement below is TRUE about neurotransmitters? The entry of neurotransmitter through K* channels into neurons triggers the rising phase of the action potential. Neurotransmitters are released from muscle cells to activate motor neurons in the presence of botulinum toxin. O Neurotransmitters are released from a neuron when the action potential reaches the end of its axon. O All of the above.arrow_forwardWHAT IF? If all the Ca2+in the fluidsurrounding a neuron were removed,how would this affect the transmission ofinformation within and between neurons?arrow_forward
- WHAT IF? Suppose you are standing at the edge of acliff and suddenly slip, barely managing to keep yourbalance and avoid falling. As your heart races, you feela burst of energy, due in part to a surge of blood intodilated (widened) vessels in your muscles and an upwardspike in the level of glucose in your blood. Why mightyou expect that this “fight-or-flight” response requiresboth the nervous and endocrine systems?arrow_forwardQ4.1. The image below shows a neuron's response to a medium-intensity stimulus. Which of the options underneath it correctly shows a signal for a weaker stimulus? Time (ms) 60 Time (ms) Time (ms) 60 Time (ms) Time ms) 60arrow_forwardA&P1 How does an antagonist differ from an agonist (prime mover)? How is it the same?arrow_forward
- Q4.8. Which statement below is TRUE about the voltage-gated Na* channels during the action potential? The voltage-gated Na* channels are open the entire time that the neuron is depolarized (when Vm is above resting potential). The voltage-gated Na* channels open after the voltage-gated K* channels. The voltage-gated Na* channels open to restore Vm to the resting potential after the action potential peak. The voltage-gated Na* channels are open when Vm is rapidly increasing during the action potential.arrow_forwardIs the sentence true or faluse ??! Synaptic vesicls store calcium.arrow_forwardDescribe how blood sugar (e.g. glucose plasma concentration) is regulated with the hormones, insulin, and glucagon. For this feedback loop, identify the following components of the feedback loop: stimulus, receptor, control center, efferent pathway, effector, and response. Be comfortable with this feedback loop to be able to describe the effects of changing various components of the feedback loop.arrow_forward
