Multiple anterior rootlets arise from the spinal cord and merge to form a single anterior root. which contains Anterior roots contain motor axons only.
These axons arise from cell bodies in the anterior and lateral horns of the spinal cord.
Posterior rootlets arise from a single posterior root,which contains sensory axons only.

Mutualism- in which two different organisms interact, and each organism benefits each other (think "positive, positive"; or " +,+ ").
An example would be Oxpeckers and zebras or rhinos - In this relationship, the oxpecker (a bird) lives on the zebra or rhino, sustaining itself by eating all of the bugs and parasites on the animal.
The bird benefits by having a readily available source of food.
The zebra or rhino benefits from having the bugs removed. Also, when there is a danger to the zebra or the rhino, the oxpecker flies high and makes much noise in order to alert nearby animals to the impending danger (i.e. a predator).
