Kinesiology is the study of movement.

To study the movment (elements of Kinesiology) you need to know:
Psychomotor behavior

Kinesiology can be defined as the study of the various disciplines that encompass the movement of the human body. There are two forms: pure and applied. Pure kinesiology seeks to understand human movement in order to analyze problems and come up with treatments for these problems. Applied kinesiology is a specific method to treat these problems. Rather than a single discipline, kinesiology is an umbrella class of study that covers many different areas. The primary focuses are human physiology, biomechanics, and anatomy. Study of this field may also cover the psychology, philosophy, ecology, and even sociology of sports and exercise.

This means that, while studying kinesiology, a student will get a broad understanding of most things that can relate to human movement. By studying anatomy, the student learns about the various parts of the human body — where bones are, where muscles attach, the locations of organs, and other locative information. By studying physiology, he or she learns how these various parts of the human body move and interact with one another. By studying biomechanics, the student takes this to the next level, using principles of engineering to gain a better understanding of human physiology and the limits of the system.

To further improve the understanding of human movement, a student of kinesiology may study related disciplines as well. Since a kinesiologist may often be called upon to deal with athletes or gym patrons, an understanding of the philosophy, psychology, and sociology of sports and exercise is often studied. This allows professional to make sure he or she can help the client get the most out of an exercise regimen, or bring a sport to the next level.

The study of kinesiology is used in many different fields. Often, gym employees will have a degree in this subject in order to better help their patrons. Physical therapists may have undergone substantial kinesiology training so that they can help their patients recover more quickly. Sports teams will employ a number of kinesiologists to help their athletes maximize the use of their bodies, prevent severe injuries, and contribute to the overall health of the team. In this context, it is very similar to the study of sports medicine.

Articular System

The articular system is a series of joints that allow movement of the human body. The study of joints is called arthrology.

When two or more bones come together, that is called an articulation. There are many different kinds of articulations, some with movement, some not.

Classification of Joints

Synarthrosis - a joint that lacks synovial fluid and is held together with fibrous tissue. Mostly immovable
Sutures - unite the bones of the skull
Syndesmosis - a joint that is connected with ligaments between the bones. They offer slight movement. A good example is the tibia/fibular head articulation
Gomphosis- A cone shaped process is held with ligaments
Amphiarthrosis - Slightly moveable joints, held together by hyaline cartilage.The ribs and the pubic symphysis are a good example.
Diarthrosis- Moveable joints with articular cartilage and a synovial sac for lubrication. These joints have additional sub-classifications by their joint movement

Pivot joint - bones move around a central axis, i.e. the radius/ulna
Gliding joint - allows movement in a back and forth action (carpals and tarsals)
Hinge joint- allows only flexion and extension (knee, elbow)
Condyloid or Ellipsoidal joint - can move in many directions but not rotation: has condyles (phalanges)
Ball and socket - rounded end with receiving fossa - Hip and shoulder
Saddle joint - Bones have both concave and convex regions (thumb only)
