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_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_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?

- 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_forwardQ8: what is the correct answerarrow_forwardWHAT 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_forward
- Hi please help me out with this question? Thank you!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_forwardWHAT IF?
