2
any strand of muscle or nervous tissues
In the nervous system, fiber refers to the long, thin extensions of neurons that transmit electrical impulses to other neurons or to muscles and glands. These fibers, also called axons, are covered in a protective sheath called myelin, which helps to speed up the transmission of impulses. The myelin sheath is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Damage to the myelin sheath, such as in the case of multiple sclerosis, can cause disruptions in nerve impulse transmission and lead to a range of neurological symptoms, including muscle weakness, numbness, and vision problems.

5
a type of carbohydrate that cannot be broken down by the body and instead helps regulate bowel movements and maintain a healthy digestive system
Fiber, also known as dietary fiber or roughage, refers to the indigestible portion of plant-based foods that passes through the digestive system relatively unchanged. It is primarily found in fruits, vegetables, whole grains, legumes, nuts, and seeds. Fiber comes in two main types: soluble and insoluble. Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract, helping to lower cholesterol levels and regulate blood sugar levels. Insoluble fiber does not dissolve in water and adds bulk to stool, aiding in digestion and preventing constipation. Both types of fiber contribute to overall digestive health, promote regular bowel movements, and can help prevent certain chronic diseases such as heart disease, diabetes, and certain types of cancer.
- Whole grains are a good source of fiber, which helps with digestion.
