Fingers and thumbs do not contain any muscles. Rather, they are composed of bone, ligaments and tendons. The tendons connect the skeletal structure of the fingers to the palm and forearm muscles to make movement possible.
More about fingers:
- The skin on the fingertips has many more nerve endings compared with most of the body.
- Contrary to popular belief, cracking the knuckles will not cause arthritis.
- On average, women have longer index fingers and men have longer ring fingers.
