The parasympathetic nervous system is responsible for ejaculation in males.

Use the following to answer questions : Scenario I The scenario is based on and presents fabricated data consistent with the following study: Caspi,A. ,Sugden,K. ,Moffitt,T.E. ,Taylor,A. ,Craig,I.W. ,Harrington,H. ,McClay,J. ,Mill,J. ,Martin,J. ,Braithwaite,A. ,& Poulton,R.(2003).Influence of life stress on depression: Moderation by a polymorphism in the 5-HTT gene.Science,301(5631),386-389. The serotonin transporter gene codes for the serotonin transporter,a protein that transports serotonin from the synapse to the presynaptic neuron.Several polymorphisms of the gene exist,including a "short" (s)and a "long" (l)variation.As humans receive one copy of the gene from each parent,people can be grouped into three groups based on this genetic variation: s/s (two copies of the short gene),s/l,and l/l.Caspi et al.(2003)interviewed participants in each of these groups and asked them a wide range of questions to determine both the degree of exposure to stress and the number of depressive episodes participants had experienced in their lives.Fabricated results consistent with their major findings are shown in Figure 3.1. Figure 3.1 -(Scenario I)An individual has two copies of the small variation of the serotonin transporter gene and has been exposed to a high degree of stress over the course of her lifetime.Based on the results shown in the scenario,one could:

After the action potential reaches its maximum,membrane channels return to their original state and _____ flow(s)_____ the cell.

During the refractory period,a chemical "pump" moves:

A copper wire is to rubber insulation as a(n)_____ is to a _____.

In the last few years,Karen has been experiencing extremely low levels of sexual desire.Recent research indicates that Karen may have low levels of which hormone?
