Imagine a life without your thumb. So Why Thumbs and What are Thumbs so Important to Humans?
The thumbs are the first digits on the hand and are located opposite the fingers. They are unique in that they are able to rotate and have a greater range of motion than the other digits, which allows them to be opposable. This allows humans and other primates to grip and manipulate objects, which is one of the key adaptations that led to the development of human intelligence.
The thumb also has its own set of muscles, ligaments and tendons. The muscles that move the thumb are located in the forearm, and are called the flexor pollicis longus and extensor pollicis longus. These muscles allow the thumb to move in different directions, such as up, down, in and out.
