Question 1

Injureor damagebody cells stimulatpain through which of thfollowing pathways?

Accepted Answer

A) pain receptor transmits signal to sensory neuron; sensory neuron releases chemical indicating pain to a motor neuron; motor neuron synapses with interneurons in the brain; the brain processes the information. 
B) chemicals released by motor neurons stimulate pain receptors; pain receptors transmit signals to sensory neurons in the brain stem; sensory neuron synapses with interneurons in the brain; the brain processes the information. 
C) negative chemicals released by damaged cells stimulate pain receptor; pain receptor transmits signal to sensory neuron; sensory neuron synapses with interneurons in the brain; the brain processes the information. 
D) all of these are possible, depending on the cause of the pain 
E) none of these are possible
