Types of Joints

Have you ever noticed that we can bend or rotate our bodies at areas where two portions of our bodies appear connected, such as our elbows, shoulders, and necks? Joints are the names given to these locations. Can you think of any others? Do you believe we’d be able to move in any way if we didn’t have any joints in a human body? What precisely is connected to these types of joints in a human body? Touch the top of your head, face, neck, nose, ear, back of the shoulder, hands, and legs, including the fingers and toes. 

The movements of the human body

Before we look at the different types of animal motions, let’s take a closer look at some of our own. Undertake you like to do physical activity at school? When you’re doing different exercises, how do you move your hands and legs?

Do your fingers feel like they’re being pressed against something hard? The bones are rigid structures. Rep this exercise on different regions of your body. There are so many bones! There are many bones present in each part of the body. Let us learn about six types of joints.

Ball and Socket Joint 

Form a cylinder out of a strip of paper. Please make a small hole in an old rubber or plastic ball and insert the paper cylinder into it (with supervision). You may also use the cylinder to attach to the ball. In a shallow dish, place the ball. Is the ball able to freely rotate inside the bowl?

Is the paper cylinder rotating as well? Consider the paper cylinder to be your arm and the ball to be the end of it. The bowl resembles the joint that connects your arm to your shoulder. One bone’s rounded end fits into the cavity (hollow space) of the other. A joint like this enables movement in all directions.

Pivotal joint 

A pivotal joint is where our neck meets our head. It permits us to swivel our heads to the right or left and bend our heads forward and backwards. Try out some of these moves. How are these motions different from our arms’?. A ball and socket joint, which can spin in a full circle? A cylindrical bone spins in a ring in a pivotal joint. 

Hinge Joint 

Open and close a door several times. Keep a close eye on the door’s hinges. They enable the door to open and close. Let’s look at the many types of movement that a hinge allows. Make a cylinder out of cardboard or thick chart paper. Make a half-cylinder out of cardboard that easily fits the rolled-up cylinder inside. The rolled-up cylinder sits within the hollow half-cylinder, moving like a hinge. 

Ellipsoid Joint

Ellipsoid joints are also referred to as ‘condyloid joints.’ Ellipsoid joints enable side-to-side and back-and-forth movement. 

Fixed Joint

Some of the joints between the bones in our skull are different from the ones we’ve discussed so far. This category of joints prevents the bones from moving. Fixed joints are the name for these categories of joints. Isn’t it true that you may move your lower jaw away from your head when you open your mouth wide? Now try moving your upper jaw. Is it possible for you to relocate it? A fixed joint connects the upper jaw to the remainder of the skull. Only a few joints that link our body’s sections have been explored. What gives the body’s various sections their distinct shapes? 

Saddle Joints 

A saddle joint is a biaxial, moveable joint that may move in two planes: flexion and extension, as well as abduction and adduction. This joint is produced chiefly between the bones, which have both concave and convex areas on their articulating surfaces.

What would you make first if you wanted to make a doll? Isn’t this a framework for giving the doll form before building the outdoor structure? Our bones work together to construct a framework that gives our bodies structure. The skeleton is the name given to this structure.

Skeleton system

How do we know the forms of our body’s many bones? By touching the form and quantity of bones in various places of our body, we may understand their shape and number. Examining X-ray scans of the human body is one technique to learn more about this form. Have you or a member of your family ever had an X-ray taken of any area of your body? When we are injured or have an accident, doctors may utilise these X-ray scans to see whether there has been any probable bone damage.

X-rays reveal the forms of our bodies’ bones. Feel your forearm, upper arm, lower thigh, and upper leg for bones. Try to figure out how many bones are in each section.Make a bend using your fingers. Is it possible for you to bend them at every joint? What is the number of bones in your middle finger? Feel your palm’s backside. Do you have a flexible wrist? It is made composed of carpels, which are tiny bones?

Conclusion

The body region where two or more bones unite to facilitate movement is called a joint. The more comprehensive the range of motion, the greater the danger of damage since the joint’s strength is diminished. Ball and socket, condyloid, hinge, pivot, saddle, and gliding are the six types of freely moveable joints. A different set of joints enables us to do different work. Inflammation (pain and swelling), infection, and injury are common causes of joint discomfort. Ligaments are tight bands of connective tissue that hold joints together and support them. As the bones move against one another, smooth cartilage reduces friction.
