Question

Sensory neurons carrying action potentials from pain receptors synapse within the spinal cord with interneurons. These interneurons synapse with motor neurons leading back to an effector and ascending neurons that carry action potentials toward the brain. This is an example of a(n) _____ pathway. A. convergent B. divergent C. reverberating D. sensory E. bifurcated

Answer 1

Correct answer is option "B"

Explanation:

• Divergent pathways found in sensory pathways of the CNS.

• Somatic senses are the senses that have to do with touch. Tickling and pain, like on Patrick's legs, are somatic senses, but so are other things that you might not think of right away, like temperature and movement. Somatosensory pathways relay information between the brain and nerve cells in the skin and organs.  
• The nerves the connect the body to the spinal cord and the spinal cord to the brain are called afferent nerves, and they send information from the body to the brain.
• Hence, the correct is option b "divergent"

Answer 2

The correct answer is (B).

Explanation:

• This is an example of Divergent Pathway.
• Divergent pathway happens when there is a synapse of smaller amount of presynaptic neurons with a postsynaptic neurons which are larger in number.

• Divergence pathway allows one part of the nervous system to cause affect in more than one other part of the system.
• Divergence pathway help the neuron to communicate with other neurons in a network.
