Joints are found where any two bones convene. They allow the skeleton to move since, in their absence, it would be impossible for human beings to move. Major body joints in human beings are classified into three.
These include rigid/Fibrous, synovial/ freely movable, and slightly movable/Cartilaginous joints. Rigid joints do not move, and an example of these joints is the skull. This is to save the brain from harm.
Slightly movable joints allow human beings to move in a restricted manner. An example of these joints is the vertebrae and the spine. The spine is connected by cartilage, and every vertebral column in the spine moves according to the one on top and underneath it (Rickards 92).
Synovial joints have a fluid known as the synovial fluid. These are the main joints in the body, and the fluid permits the joints to move about liberally and reduce friction.
Synovial joints are the majority in the human body and include pivot, ellipsoidal, hinge, saddle, ball and socket joint and finally the gliding joint. Ball and socket joint usually moves in all ways and is supported by the ligaments. An example is the joints found in the hip and shoulders.
Shoulders concentrate on military actions. The hips and shoulders allow the highest freedom in movement. Joints in the shoulders must be movable enough for the broad range of arm and hand activities. The joints also make the shoulder firm enough to allow for activities such as lifting and pulling.
Joints found in the knee and elbows are examples of hinge joints. Hinge joints have the capability of moving backwards and forward. The knee as a hinge joint centers on dead lifts and squats. The elbow focuses on twists and extensions of the triceps.
The knee hinge joint permits the foot to turn sideways hence enabling it to roll and glide while walking. Pivot joints are those found in the neck and assist the head to move sideways. These joints allow a revolving or twisting movement just like the head moves sideways.
Ellipsoidal joints are limited in number and have partial rotation. They are found in the index finger of a human being. Saddle joints are located in the thumbs and make the thumb move sideways and grip things. They enable the human thumb to cross over the hands’ palm.
Gliding joints include the ankle and wrists. Most of these joints are related to the sternum, which is a long, even bone located on the thorax and interrelates with the ribs (Kingston 220).
Exercises that use more than three major joints
There are exercises that use more than three major joints. Examples of these exercises are swimming and cycling which use five joints. During swimming, the wrists flex to grab hold of the water.
The elbow and shoulder joints then follow to end the stroke. The hip, ankle, and knee joints are used to create the rising and falling kick. Cycling is another exercise that uses more than three joints. These include the shoulder and elbow joints that are used to steer and the knee, ankle and hip joints that are used in peddling (Kingston 220).
Learning Experience
My learning experience is that of performing exercises daily. I did exercises such as walking, jumping, swimming, and cycling. This exercises enhanced my overall body fitness. A comprehensive explanation of my findings is that exercises assist in the maintenance of joint mobility, muscle strength, and general body fitness. Mobilizing exercises are those exercises that enhance the range of movement of a joint.
It is vital to take ones joints via a wide range of movements each day. Doing housework chores may not be referred to as exercising. Special attention should be paid to stiff joints since this require more exercise. It should, however, be noted that it is wrong to compel a stiff joint to move beyond its ability.
Strengthening exercises are designed to assist the joints in putting up with body weight. They keep the joints physically powerful and stable.This newly acquired knowledge can benefit me in my future service to my future clients, friends and family since I can advise them on exercise guidelines such as performing exercises three to four times in a week.
