At which location is n (chemical messenger) released from the neuron a) A b)B c)C d)D e)EExplanation / Answer
1) Spinal cord, nerve and brain are all organs. Tract is not an organ. Therefore, the answer for this question is option c (tract).
2) The effector among the given options is muscle fibers (option d).
3) The structure which is a part of peripheral nervous system is ganglion (option b).
4) The structure which is not a part of central nervous system is nerve (option a). Central nervous system includes brain, spinal cord and tracts.
