Nervous or the nerve tissue is the major tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transfer nerve impulses and also gives nutrition to neurons.

The spinal ganglion, located in the dorsal root of the spinal nerve, contains the cell bodies of sensory neurons. These neurons transmit sensory information from the periphery (like touch, pain, or temperature) to the central nervous system (CNS). The ganglion is situated just outside the spinal cord, near the point where the dorsal root enters the spinal cord. It plays a key role in relaying sensory input to the brain.
The spinal ganglion, also called the dorsal root ganglion, is a cluster of nerve cell bodies located along the spinal cord. It is part of the peripheral nervous system and is found in the dorsal root of each spinal nerve, which is the part of the nerve that carries sensory information from the body to the spinal cord. The neurons in the spinal ganglion are sensory neurons, specifically pseudounipolar neurons. These neurons have a unique structure: a single process that splits into two branches. One branch extends to the peripheral tissues (like skin, muscles, or organs) to collect sensory information, while the other branch connects to the spinal cord to transmit that information to the central nervous system. The spinal ganglion plays a critical role in processing sensory input, such as pain, temperature, touch, and proprioception (the sense of body position). It acts as a relay station, where sensory signals are gathered and sent to the spinal cord for further processing and response.
