 Kinesiology-the study of movement  Brings together anatomy, physiology, physics, and geometry as they relate to the human bodies movement.

 Biomechanics-mechanical principles that relate directly to the human body.  Can be relative to the extremities or an implement such as a bat or racket  Can be static(nonmoving) or dynamic(moving) activities.  Read paragraph 3-4 on page 3 and paragraph 1 on page 4-6

 Anatomical Position- human body standing upright, eyes forward feet parallel, arms at side, and hands with palms facing forward.

 Linear Motion- a straight line from one point to another.  Rectilinear Motion-straight line like a player running across a field.  Curvilinear Motion- straight line but in a curved path, like a diver leaving the diving board.

 Angular Motion- Rotary motion is when all the parts of the object move through the same angle, same direction at the same time, but do not move the same distance.  When you flex your elbow your hand and wrist travel a different distance through space.

 Generally speaking most movement within the body is angular, most movement outside the body is linear.  Get into groups of 3 and create a list: 2 linear movements 2 angular movements 2 combination movements

 Arthrokinematics: relationship of joint surface movement. The humeral head’s movement within glenoid fossa of scapula.  Osteokinematics: relationship of the movement of bones around a joint axis. Humerus moving on scapula

 Movements of Synovial Joints  Flexion-decrease angle between 2 bones  Extension-increase angle between 2 bones  Hyperextension-increase angle between 2 bones beyond the normal range of motion (ROM).

 Movements of Synovial Joints  Abduction-Limbs only-limb moves away from the midline of the body.  Adduction-Limbs only-limb moves toward the midline of the body.  Rotation-when a bone turns on its axis towards or away from the midline of the body

 Movements of Synovial Joints  Circumduction- the ability of a limb to move in a circular path around an axis.  Supination- moving into a supine position.  Pronation- moving into a prone position.  Plantarflexion- pointing toes down, “planting the foot”  Dorsiflexion- bringing the toes up

 Movements of Synovial Joints Plantarflexion- pointing toes down, “planting the foot” Dorsiflexion- bringing the toes up

 Movements of Synovial Joints  Inversion- turns the sole of the foot inward, medially.  Eversion- turns the sole of the foot outward, laterally.  Protraction- occurs in the transverse plane, moving the body part forward  Retraction- occurs in the transverse plane, moving the body part backward

 Medial-Middle/Midline  Lateral-outside

 Distal- far from midline  Proximal- close to midline

 Superior- above another structure  Inferior- below another structure

 Anterior- front  Posterior- back
