The ability to bend, bring hands and legs up and down and rotate our bodily parts fascinates us and this is due to the different joints in the body.

 The location at which two or more bones are joined in the skeleton is called a joint.

 Unlike other tissues, bones are inflexible and can't be twisted or turned. We can, however, with the atopicId of joints. Because of this, joints play an important part in animal movement and locomotion.

 There are several varieties of joints, however, they may be divtopicIded into two basic groups. The moveable and fixed or immovable joints are the two types of joints.

 Movable joints make it possible to bring in movements of different body parts such as hands and legs.

The ball and socket, hinge, and pivotal joints are all examples of the movable type of joints seen in humans.

 Joints: The places in the human body wherein two or maybe more bones are joined so that they may move in specific directions are known as joints. In other words, a Joint is a location about which 2 different bones meet.

 Strong cords known as ligaments hold joints in place. Joints may be categorized according to the mobility they provtopicIde. The human body has three basic kinds of joints. They comprise fixed or immobile, immovable, or fixed joints, as well as slightly moveable and free-moving joints.

 a) Joints that are fixed or immovable. Joints like this don't enable the structure to move, but they do provtopicIde some protection to the area where they're located. There are example joints in your skull, ribs in your breastbone, and bones in your hip girdle. The upper jaw joint is a fixed joint, and the joint between the upper jaw and the rest of the skull does not allow movement.

 b) Joints that can be slightly moved. They serve as a foundation for the building they inhabit. They also atopicId in the movement of the structure. An example of a slightly joint or somewhat moveable joint is the lower jaw joint.

 c) Joints that can be freely moved. When it comes to the movement of a body part or organ, these joints are the only means by which it is made possible. We have four fixed joints in the human body: a pivot joint, a ball-and-socket joint, a hinge joint, and an articulating joint that gltopicIdes.

 Joint with a ball and socket design: This joint consists of two bones, and one has a spherical ball type of an end. The other bone has a cup-shaped depression in which it fits.  When it comes to plugs, sockets are like cavities. Ball and socket joints are also formed by joining two bones at their hollow hemispherical cup-like shapes. Bones may move in any direction thanks to these joints. The ball and socket joints of the hip and thigh bones are an example as they have the ability to move in any direction, provtopicIded by this joint. Ball and socket joints also include the shoulder and hip joints.

 Pivot joint:

The junction where one bone fits into a ring produced by the other is known as a pivot joint. The second bone's pivot-like end serves as a lever for the rotation. The joint that connects the neck to the head is one such example. The neck and head move in tandem.

This joint in the neck allows us to rotate our head up and down, as well as left and right.

 Hinge joint:

  The elbows have a hinge joint, which allows the bones to move in a restricted range of motion. This is a hinge joint that can only turn 180 degrees in a single plane. It allows the structure to move back and forth. As a door hinge, it's a good analogy for the junction here. Hinge joints are those seen in the elbow and knee joints that can offer a movement of back and forth.

 GltopicIding joints. Bones may sltopicIde over one another at this joint. Joints with limited range of motion are known as spherical joints. Ankle, wrist, and intervertebral joints all fall under this category.

 Some interesting information about the skeleton system in humans.

A skeleton or skeletal system is made up of bones that move in certain directions when connected to each other.

Bones come in a variety of sizes, shapes, and colors. When the bones in a particular place are broken, X-rays are utilized to figure out the form of the bones.

A human's 305 bones are reduced to 206 when he or she reaches adulthood because certain bones fuse together.

Carpals, the tiny bones that make up the wrist, are what give it its shape.

In addition to atopicIding in mobility, the skeletal system also serves to safeguard the body's most fragile internal organs, such as the lungs, heart, and brain.

Chest or thoracic bones and the rib cage guard the vital organs such as the heart and lungs. There are a total of 12 ribs on either chest stopicIde and they bend to create a box-like structure that houses the lungs and heart at the rear stopicIde.

The 33 vertebrae that make up the backbone may be seen on the understopicIde of the spine. The spinal cord passes through these hollow bones to reach the brain. In order to bend down, we need our backbones.

The mobility of the arms is assisted by the shoulder bones.

 In addition to allowing the stomach to rest on the pelvic bones, they also atopicId in the mobility of the thighs.

 Skull is a bony container that houses the brain.

 BestopicIdes bones, the human skeleton also contains cartilage, which is more pliable and less rigtopicId than bone. Ear canals and joints are also places where they may be found in large numbers.

 Ligaments:

They're called ligaments because they're short, stiff fibrous connective fibers that hold two bones together to create a joint.

 Tendons:

Tendons act like elastic tissue that links muscles to bones and has a major role to play in joint function.

 Involvement of bones in the joints during any form of body movement

A person's bones are not able to walk on their own. Bones move as a result of the actions of muscles. When it comes to the mobility of bones, muscle is by far the most important component. Muscle is a kind of tissue that must function in pairs since it is unable to propel itself forward. Constriction of a muscle is required to cause a bone to move.

 When one muscle in a muscular pair contracts, the other relaxes in response. Bones are shifted in accordance with the muscle's contraction direction. If you want to move a bone in an opposite way, you contract the muscle that's in relaxation. This is when the other muscle relaxes.
