If an effector muscle cannot contract even after receiving a signal, which link of coordination will be considered failed?
Answer and explanation
Correct answer: The response-producing link
The governing concept is the receptor–coordinator–effector pathway. A receptor detects the stimulus, the nervous system processes the information and transmits a command, and the effector produces the final response. If the muscle receives the signal but cannot contract, detection and transmission may have occurred, while the response-producing effector link has failed. Therefore option A is correct. The other options refer to earlier stages or to hormonal secretion, which is not required for every muscle response.
