Question

Define the function of : Afferent pathway, Dorsal root ganglion, Efferent pathway, Motor neuron.

Answer 1

Afferent pathway is the pathway involved in carrying nerve impulses from the sensory organs to the spinal cord through the sensory neurons. The dorsal root ganglion is the region in the pathway that contains the cell bodies of the sensory neurons. Efferent pathway is the pathway involved in carrying nerve impulses from the spinal cord to the peripheral (efferent) organs. Motor neurons are the neurons involved in carrying impulses away from the spinal cord and are involved in the efferent pathway.
