What are the horns of the spinal cord made of?

What are horns in spinal cord?

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.

What are spinal cords made of?

The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter, is uniformly organized and is divided into four regions: cervical (C), thoracic (T), lumbar (L) and sacral (S), (Figure 3.1), each of which is comprised of several segments.

How can you distinguish between the anterior and posterior horns?

1, the gray matter is subdivided into regions that are referred to as horns. The posterior horn is responsible for sensory processing. The anterior horn sends out motor signals to the skeletal muscles.

What are gray horns?

The gray matter forms three pairs of horns throughout most of the spinal cord: (1) the dorsal horns, composed of sensory neurons, (2) the lateral horns, well defined in thoracic segments and composed of visceral neurons, and (3) the ventral horns, composed of motor neurons.
