Detailed explanation-1: -Like the brain, the spinal cord consists of gray and white matter. The butterfly-shaped center of the cord consists of gray matter. The front wings (usually called anterior or ventral horns) contain motor nerve cells (neurons), which transmit information from the brain or spinal cord to muscles, stimulating movement.

Detailed explanation-2: -Grey matter in the spinal cord is known as the grey column which travels down the spinal cord distributed in three grey columns that are presented in an “H” shape. The forward-facing column is the anterior grey column, the rear-facing one is the posterior grey column and the interlinking one is the lateral grey column.

Detailed explanation-3: -Butterfly vertebra is an uncommon congenital anomaly of the spine, which is generally benign. Butterfly vertebra was first described in 1844, and is known variously as: cleft vertebra, sagittal cleft vertebra, anterior rachischisis, anterior somatoschisis, and anterior spina bifida.
