Respuesta :
White matter is white because it is covered with a fatty protein called myelin. So yes, the answer is c :)
The white and fatty tissue concentrated in the spinal cord is the myelin sheath. So the correct option is C.
What is myelin sheath?
Myelin sheath is a layer made of fats and proteins that surrounds the spinal cord and nerves. It not only provides them with insulation and protection but also increases the speed of signal transmission across nerves.
This sheath is present around the cell body of each nerve cell for maximum protection and efficient signal transmission. Myelin sheath also helps to maintain the strength of the signal transmitted across the nerve cells.
Therefore, the myelin sheath is extremely important and any damage to it can result in the slower or weaker transmission of signals or it can also result in direct nerve damage. Multiple sclerosis is a disease that attacks the myelin sheath.
Myelin sheath is also damaged due to an immune defect in which the immune cells treat it like a foreign object. The symptoms for this depend on where the myelin is being attacked. The destruction of myelin is dubbed as demyelination
Therefore, the correct option is C.
