Hand and bone structure

In hurumanu 2 we have looked at the hand - how much bones does it have and what makes the hand move. There are 27 bones in your hand. 5 bones in your palm, 8 bones in your wrist, and 14 bones for your fingers.

 

Tendons:

What is a tendon? 

A tendon is a stringy connective tissue that attaches muscle to the forearm bone which allows your phalanges (fingers) to move up and down. Tendons also attach muscles to the structure such as the eyeball.   

 

Muscles:

The muscles in your hand are Thumb Muscles, Palmar Muscles, and Little Finger Muscles. The main muscle in your hand that moves your phalanges is called Flexor Digitorum Profundus. This muscle is in the forearm which flexes the fingers to move, contracting, and relaxing the tendons. 

 

Ligaments:

The ligaments are strong bands of connective tissue that attaches to the bones to support them and keep them in place.  Ligaments also help the structure of movement for your fingers so they aren't jelly.
