Hand Structure
Introduction
The hand marks the end of the arm in humans and other primates, distinguishing us from many other species through our ability to grasp and manipulate objects. While some animals have appendages that function similarly to hands, such as the paws of dogs and cats, they aren't scientifically classified as hands.
Anatomy of the Hand
A key feature of hands is the presence of opposable thumbs, which enable us to grip objects efficiently. Human hands consist of a palm, five digits, and are connected to the forearm by the wrist?"a joint known for its agility. However, the wrist isn't considered part of the hand, so let's focus on the fingers.
The palm supports the fingers, allowing them to bend and hold items. The thumb is positioned on the far side of the palm and can rotate 90 degrees, providing greater dexterity compared to the other fingers, which can rotate approximately 45 degrees.
Finger Names
Starting from the outer edge of the palm, the fingers are named as follows: thumb, index finger, middle finger, ring finger, and the smallest finger, commonly known as the 'pinky.'
By understanding the unique structure of the human hand, we gain insight into its remarkable functionality and versatility.
