As you might already know, the human hands comprise of several bones as well as some moving parts that make them distinct from other parts of the body. All these work together provided that they are not deformed and are in good condition.
More than that, our hands perform many various tasks. They can work on all things ranging from delicate ones to tough labors. These could be a few of the reasons why having healthy and normal hands is a great blessing to be thankful for.
It is difficult to live life if our hands are deformed or disabled – this is obviously clear indication why they are perceived as one of the valuable components of our body. Therefore, it is just right that we take better care of them.
Here is a list of some of the most important parts that you need to delve into about the human hands:
- The human hand consists of a total of 29 joints, 27 bones and 123 identified ligaments.
- The blood vessels are the ones responsible for carrying blood to and from the hand. The muscles that set the fingers in motion are quite vigorous. They are vigorous enough to execute tough jobs that could support your entire weight.
- The joints serve as the places where the bones are in consonant with each other; hence enabling any sorts of movements to be done.
- The nerves are the ones that transmit and receive messages; as a result, this enables a person to feel and be able to execute some direct movements.
- The bones play vital role in that they serve as the tough tissues that provide the hands their stability and shape.
- The muscles, on the other hand, are the soft tissues that relax and contract to make it possible for the hands to be moved.
- The wrist bones are called carpals.
- Ligaments pertain to soft tissues that balance the joints and connect bone to bone.
- The finger bones are referred to as phalanges.
- The ones that link the muscle to the bone are tendons that look like cord tissues.
- The synovial lining is the part of the hand that is responsible for producing the fluid inside the joints that specifically aids in making various movements as smooth as possible.
- The tendon sheaths are the tubes that safeguard, surround and manage the tendons. What is more, these tubes are filled with liquid.
- The palmar fascia refers to the solid layer of soft tissue that works primarily to help get our palms balanced.
- Meanwhile, the volar plates pertain to the hard tissues that balance the joints; thus, these are responsible for preventing our fingers from bending backward.
- The fingers are tiny distal parts of a limb. Over and above, both humans and animals utilize the fingers to deal with their environment and this is made possible through the sense of touch.
- The middle component of the hand bones are referred to as metacarpals.
- The hand consists of a network of veins that are known as median, ulnar and radial nerves. On the other hand, the back part of the hand is also known as dorsal opisthenar area.
Sensory and motor nerves are the two kinds of nerves found in the hand. The ulnar nerve works in regulating the other muscles in the hand, the median nerve is the one that provides the fingers and wrist with movement and motor nerves work to stimulate the abductor of the thumb and the fingers’ extensors.
- Our fingers are comprised of the thumb, index, middle finger, ring finger and little finger.
- Joint capsules are composed of veined connective tissues that enclose the joints. Found inside these is the synovial membrane that is sole responsible for supplying synovial fluid to smoothen all the joints.
- Cartilage is a hard but bendable tissue which is known for being quite functional at weight bearing.
Our hand is comprised of plenty of structures that specifically have a very substantial role in healthy hand function. Take into consideration that conditions that alter the manner these parts function could immensely influence whether the hand works healthily.
If you’re going to dig deeper, you will realize that the human hands are works of wonders. They aren’t that huge but they are capable of executing all the tasks for us. Can you imagine yourself living without healthy hands? This is why you should take good care of them at all cost!
