Hands are one of the upper parts of our body. In Latin, it is known as Manus. It is made up of palm, wrist, and fingers. They permit us to do many of our daily actions such as lifting things, writing, and cooking.

It comprises almost 27 bones, 34 muscles, 27 joints, and more than 100 ligaments and tendons, nerves, and blood vessels. The hand of a human has a wide palm with five digits connected to the forearm by a joint called the wrist.

They are an important part of our body. Hands do various functions for us.  With the help of hands, we can touch, push, pull, sweep, and carry anything. They make us able to do a broad range of tasks including touching, gripping, feeling, holding, manipulating, and stroking.

The bones in the hands give support and movement to the soft tissues. A hand can hold and move objects in different ways such as with a power grip or accuracy grip. The volume, form, load of the object, and ease of handling determine which of these two approaches is used. Power grip is generally better suited for large and heavy objects and the precision grip is used for small and delicate objects.

In hands, the bones are sub-divided into three main bones which are:

  • Carpal Bones
  • Metacarpal Bones
  • Phalanges

Carpal Bones:

These are the 8 bones that form our wrist. These bones are managed into two rows named as:

  • Scaphoid
  • Lunate
  • Triquetrum
  • Trapezoid
  • Trapezium
  • Capitate
  • Hamate
  • Pisiform

Metacarpal Bones:

These are the 5 bones that make up the center part of the hand which are:

  • Thumb
  • Index Finger
  • Middle Finger
  • Ring Finger
  • Little Finger


These are the 14 bones that compose the fingers of the hands. Also, it makes the toes of the foot. The thumb has 2 phalanges while the other of each finger has 3 phalanges.


In hands, the muscles are subdivided into two groups which are:

  • Extrinsic Muscle
  • Intrinsic Muscle

Extrinsic muscles:

They are created in the forearm or elbow. They manage the movement of the wrist and hand. These are responsible for the entire movements of the hand. They keep the wrist and hand in place while the fingers do fine motor movements.

Intrinsic muscles:

They are small muscles that are created in the wrist and hand. They are responsible for fine motor movement of the fingers during actions such as writing or playing the piano.


Every finger has 6 muscles including 3 extrinsic and 3 intrinsic muscles which control its movement. The index and little finger both have an additional extrinsic extensor.


In hands, there are 3 main nerves which are:

  • Ulnar Nerve
  • Radial Nerve
  • Median Nerve

Ulnar Nerve:

This nerve crosses the wrist through a region called the Guyon canal and branches to give feeling to the little finger and half of the ring finger.

Median Nerve:

This nerve crosses the wrist through a tunnel called the carpal tunnel to give sensation to the index finger, part of the ring finger, palm, thumb, index finger, and middle finger.

Radial Nerve:

This nerve runs downward the thumb side of the arm to give sense to the backside of the hand from the thumb to the longer finger.

Blood Vessels

These vessels provide blood to the hand beside the nerves. The arteries in the hands are:

Radial Artery:

This artery is a huge blood vessel that gives oxygenated blood to the side of the:

  • Forearm
  • Wrist
  • Hand

Ulnar Artery:

This artery supplies blood to the:

  • Forearm
  • Hand
