Veerle Rots has written: 'Prehension and hafting traces on flint tools'
A ruminant, such as a cow, goes about prehension by using its tongue to gather food, but a horse or goat makes primary use of its lips. during mastication, most ruminants chew their fodder until it forms a bolus using cheeks and tongue to keep the food in the primary grinding surfaces of the back teeth.
Brains. They think with their feet. Although the above answer is sometimes true. Horses, Pigeons and yes Rats, actually lack a Gall Bladder. They do not have one, interesting, eh?
Are you referring to their method of prehension, i.e. how they pick up their food? If so, they primarily use their very mobile lips, which allow them to easily rip up grass and small brush.

A homograph is a word that is spelled the same as another word but has a different meaning. An example is "bow," which can refer to a weapon or a gesture of respect. An organ is a part of a living organism that performs a specific function.
