In Science, we have been learning about how the had worked and instead of making a hand, I choose to make a blog post.
Bones: A hand is made up of 27 individual bones, 8 carpal bones, and 5 metacarpal bones.
Bones provide structure and support.
There are 3 bones in all fingers and 2 bones in the thumb.
Ligaments: Attach bones together they allow movement certain directions only.
Muscles and tendons: There are no muscles in our fingers only in our forearm and palm.
Tendons attach the don't to muscle.
Long tendons run from the tip of our fingers down to our muscles.
The muscles then move our fingers by contracting and relaxing.
As the muscle contracts, it pulls on the tendon, making our finger curl down.
