Manus of Monkey showing Nails
A monkey’s hand is long, strong and covered with hairs, the nails are hard and sharp. They have five fingers just as humans do, even though their hands are similar to humans in some ways, there are many differences. Primates–especially those that walk on the knuckles of their hands–are not as flexible with their hand movements. The wrist bones of the knuckle-walkers keep their hands from bending or extending while they put pressure on their knuckles. They have a relatively small thumb on comparison with other fingers and little used in swinging. The hand is specialized for ’brachiation’ hand-over-hand swinging through the trees. Digits two to five are elongated and used in clasping tree limbs. The thumbs are opposable that they use in the same way that humans do. However, they have these thumbs on both their hands and their feet which humans don’t have. They can peel fruits, they can pick up objects, and they use the thumbs for grooming..
