Question

In reflex pathways:__________ a) the receptor is a membrane protein b) the efferent is always a motor neuron or hormone c) the efferent is the cell or tissue that does the final work in the pathway d) the integrating center for a neural or neuroendocrine reflex is always some part of the CNS

Answer 1

Answer:

D

Explanation:

The neural pathway regulates the action reflex. At times sensory neurons synapse occur in the spinal cord rather than the brain, this allows for a quicker reflex action. Synapses in the spinal cord activate spinal motor neurons without delay, which is likely the case if the signals go to the brain, the brain doe however receive the sensory input during the reflex action.
