GENERAL HISTOLOGY

Detailed explanation-1: -The dorsal root fibers are the axons originated from the primary sensory dorsal root ganglion cells.

Detailed explanation-2: -The dorsal root ganglia contain the cell bodies of afferent nerve fibres (those carrying impulses toward the central nervous system); efferent neurons (carrying motor impulses away from the central nervous system) are present in the ventral root ganglia.

Detailed explanation-3: -The dorsal root ganglion, more recently referred to as the spinal ganglion, is a collection of neuronal cell bodies of sensory neurons. It is the most common type of sensory ganglion in the human body. Each cell body in the ganglion belongs to what is considered to be a pseudounipolar neuron.

Detailed explanation-4: -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-5: -The dorsal root ganglia (DRGs) are located in the peripheral nervous system (PNS), between the dorsal horn of the spinal cord and the peripheral nerve terminals, and contain various cell types such as satellite glial cells, endothelial cells, macrophages and primary sensory neurons.
