AP PSYCHOLOGY

Detailed explanation-1: -DRG neurons are pseudo-unipolar neurons with a single axon that bifurcates into two separate branches, resulting in a distal and proximal process.

Detailed explanation-2: -The DRG axons ultimately make synaptic contact with nuclei of the dorsal column (30) or thalamus, at which point the information is transmitted to the cerebral cortex for further processing. Thus, DRG neurons serve as important centers of communication between the peripheral and central nervous systems.

Detailed explanation-3: -Sensory neurons with cell bodies situated in dorsal root ganglia convey information from external or internal sites of the body such as actual or potential harm, temperature or muscle length to the central nervous system.

Detailed explanation-4: -The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia.
