What is a horse's organ of prehension?

The organ of prehension in horses refers to the part of the anatomy that facilitates the grasping and taking in of food. In horses, the lips play a crucial role in this process. They are highly sensitive and allow the horse to pick up and manipulate their food, aiding in the act of grazing.

While the tongue is also important as it helps in maneuvering food once it has been grasped, the primary organ responsible for prehension is the lips. They can effectively grasp grasses and other forage, enabling the horse to feed effectively.

Teeth and gums are important for the chewing process but are not directly involved in the initial grasping of feed. Therefore, when discussing the organ specifically responsible for prehension in horses, it is clear that the lips are the correct choice.
