GENERAL HISTOLOGY

Detailed explanation-1: -The gray matter is the area of the spinal cord where many types of neurons synapse. In the. dorsal horns (or posterior horns), many incoming sensory neurons synapse with interneurons, which then distribute information to other parts of the spinal cord and brain.

Detailed explanation-2: -At the back of spinal cord the central grey matter forms two arms, each called a Dorsal Horn. The dorsal horns contain the cell bodies of sensory neurons. Two arms located at the front of the spinal cord, central grey matter are called ventral horns. They contain the cell bodies of motor neurons.

Detailed explanation-3: -The spinal cord dorsal horn contains the first relay for afferent inputs from the skin, muscles, and viscera of the body. The superficial dorsal horn contains at least some neurons that maintain the selectivity for modalities encoded by the primary afferent endings.

Detailed explanation-4: -Gray Horns The posterior horn is responsible for sensory processing. The anterior horn sends out motor signals to the skeletal muscles. The lateral horn, which is only found in the thoracic, upper lumbar, and sacral regions, is the central component of the sympathetic division of the autonomic nervous system.
