The posterior horn is a section of gray matter in the spinal cord, primarily involved in processing sensory information that arrives from various parts of the body. It serves as a critical relay point for sensory signals on their way to the brain.
The part of the central nervous system consisting primarily of neuron cell bodies and lacking myelinated axons, involved in processing and integrating information.
Sensory Neurons: Nerve cells that transmit sensory information (e.g., feeling, hearing, seeing) from both external and internal environments to the central nervous system.
A long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column, acting as a major conduit for information traveling between the body and brain
