The hand is a very important part of the body and all of our daily activities involve them in some manner. Hands have multiple parts and each has a different role to play in various activities. We use hands for writing and painting like delicate works where the movement is very fine and controlled. We use our hands to eat as we form a bite of rice mixed with curry and push it with the thumb into our mouth.
We use hands for clapping which is a gesture of praise and congratulations. The hand is also used for gripping objects, writing anything, etc.

Various Parts of a Hand
Fingers- The fingers are the key part of the hand as they are the ones that provide the grip and grasp on an object and it happens because fingers can fold in a circular fashion because of small bones that can curl inwards. These individual segments are called Phalanges.
Thumb- The thumb is the thickest finger of the hand and completes the grip on any object. This is very essential in order to hold anything from a pen or paintbrush to a dumbbell in the gym, we secure a grip with the thumb.
In today's day where typing on a smartphone is a daily need and essential activity, the thumb is very useful in that case as well.
Index Finger- It is the second finger on the hand and participates with the thumb for fine movement activities such as writing, painting, sculpting, etc.
Middle Finger- This finger is the longest in the hand and is sort of the source of strength while gripping and lifting an object as the weight falls upon the fingers and the middle one acts like an anchor to the rest.
Ring Finger- It is as the name suggests the finger where one wears a ring. It is the finger where rings are worn during an engagement in marriage. This finger is between the middle finger and the last finger on the hand.
Little Finger- It is the tiniest finger of the hand and it is also called the pinky finger and helps in grabbing objects tight as it is close to the palm.
Palm- It is the flat wide surface of the hand on the inner side of the hand and participates in the gripping of objects. The lines on the palm act as a grip in holding objects. It folds from the upper portion because the joints are due to the connection of the palm with the fingers.
Wrist- It is a flexible joint that connects hand with arm in order to do a lot of work. It has multiple bones and can be moved in almost all directions.
Movements of the Hand
Knuckle- It is the tough portion at the back of the hand. The knuckles allow the movement of the fingers forward and backward. It is used for combat or fighting while throwing punches. They are very important in combat sports such as wrestling and boxing.
Fingernails- These are located at the tip of every finger and are ever growing parts of the body. They can grow indefinitely. It is made up of a protein called keratin and is the same thing that hair is made of.
Hands are a privilege that only a special group of animals in the world have, i.e. primates. We can use our hands to do multiple activities like writing, swimming, clapping, etc. The human hand has about 29 major and minor bones altogether. There are a total of nine muscles that control the thumb movement. This is one of the body parts used in many actions and activities. Each and every bone and muscle work together in order for us to perform an activity with our hands.
