Responses to Autonomic Nerve Stimulation

[pic]

Figure 1. The effect of nerve stimulation (20 Hz) on the contraction amplitude in the isolated ileum.

1) Referring to Figure 1 and Table 1, briefly describe the response of the spontaneously contracting ileum to nerve stimulation. Was this response altered by increasing the voltage of nerve stimulation?

When nerve stimulation was conducted, a reduction in the amplitude of contraction
