Answer 1

Axons

Explanation:

Axons cross from one side of the spinal cord to the other through the gray commisure

• Each arm or extension of the gray matter in the spinal cord is referred to as a horn
• Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
• Projecting towards the front are the ventral horns (or anterior horns)
• In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
• A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
• In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid
