10 Questions
What is the main function of the sensory system?
To receive information about the self and environment
What are receptors in the sensory system?
Biological transducers converting energy into electrochemical energy
Where does the action potential transmitted by the sensory neuron travel to?
Dorsal root ganglion
What do the dorsal columns of the white matter in the spinal cord exclusively contain?
Ascending tracts transmitting information from the PNS towards the brain
Where do the central processes of the sensory neuron extend to after the dorsal root ganglion?
Dorsal horn of the gray matter in the spinal cord
Where are Meissner's corpuscles primarily responsible for detecting touch located?
