You really need to know the function of the lifting bones. There are various functions of the lever bones that support humans to make movements. This human bone has a function related to the movement of the hand.

The human body is composed of various bones that can support movement. The various arrangements of these bones will become one to make humans smooth in carrying out movements.
The function of the lifting bones as a support for human locomotion
Not only the ulna, but there are also other bones that make up the structure of the human forearm. The bones that exist in the forearm to form a structure, namely the radius bone.
The radius bone is located next to the ulna, parallel to the thumb below. Yes, rather than the ulna, the ulna itself has a smaller size.
The lower the shape of the radius bone, the bigger it is and forms the joints in the wrist. The top of this bone has a location close to the upper arm bone.
The blade itself has a length of approximately 20.32 to 26.67 cm. The shape of the bone resembles a pipe with marrow on the inside.
In addition, the bones also contain blood vessels and blood proteins. The radius bone is one of the parts that is prone to injury and cracks.
This radius bone has an important role to support movement in the bone structure. The following are various functions of the lever bones as a support for movement in the human body.
1. As a Place of Body Tissue Attachment
The rib cage also acts as a place for attachment to several body tissues. A number of body tissues such as blood vessels, tendons, ligaments, and muscles will be attached to this rib. Well, the body tissue that is attached to the lifting bone has various functions to support body movements.
In addition, the muscles attached to the radius can support the function of moving the forearm. While the attached tendons play a role in connecting between bones and helping joints to remain in a stable state.
2. Supports Forearm Movement
The function of the next lever bone is to support the movement of the forearm. The radius can make the forearm perform an inward or outward circular motion. The radius bones are also capable of performing movements such as stretching or bending.

In the wrist, the radius bones can help move closer to the body, stretch, bend, rotate, and away from the body. With the ulna, the ulna has a role to connect the wrist up, rotate the hand and move the wrist.
3. Provides Forearm Strength
The radius bones also play a role in providing strength to the forearm. This bone will support the forearm to carry out various movement processes. Various motion processes such as lifting or supporting heavy objects will certainly require strength.
In the composition of the human skeleton, the need for strength in carrying out the movement of the forearm will be supported by the existence of this radius. In addition, the presence of the ulna is also able to support the role of the ulna to provide strength.
4. Provides support for the balance of motion in the arms
The function of the next lever bone is to provide support for the balance of arm motion. The existence of the lifting bone can create a more stable bone structure. So that the movement of the hands can be more balanced as a whole.
This is also inseparable from the presence of the ulna as a support for the movement of the ulna. Not only that, the lever bones also act as the body’s foundation when moving the body with the help of the arms.
5. Forming Structure on the Lower Arm
The lower part of the arm will be made up of the radius and ulna. The radius and ulna bones are located extending from the wrist to the elbow. If there is no lever bone, the structure of the forearm will not be perfect.
Therefore, the existence of this lever bone also plays a role in forming a more perfect forearm structure. The existence of the lever bone can make the functions of other bones in the forearm better.

So, that was a review of the various functions of the lifting bones that you should know about. The lever bones have a big role to play in the movement of the arm. With the existence of this radius, the human locomotor will be perfectly arranged to carry out its functions. (R10/HR-Online)
