dorsal root ganglia
The dorsal root ganglia are clusters of nerve cell bodies located near the spinal cord. They are part of the peripheral nervous system and play a crucial role in transmitting sensory information from the body to the central nervous system. Each ganglion contains the cell bodies of sensory neurons that carry signals related to touch, pain, and temperature.
These ganglia are connected to the spinal nerves, which branch out to various parts of the body. When sensory receptors detect stimuli, they send signals through the dorsal roots of the spinal nerves to the dorsal root ganglia, where the information is processed before reaching the spinal cord.
