|
Kinesiology
|
the study of movement
|
|
|
|
What principles does kinesiology utilize?
|
-The principles of mechanics
-musculoskeletal anatomy --neuromuscular physiology |
|
|
|
Biomechanics
|
mechanical principles that relate directly to the human body
|
|
|
|
What is static system?
|
non-moving
|
|
|
|
What is dynamic system and what can it be divided into?
|
moving
|
Dynamic systems can be divided into kinetics and kinematics.
|
|
|
kinetics
|
The forces causing movement
|
|
|
|
kinematics
|
Are those time, space, and mass aspects of a moving system
|
|
|
|
What must a muscle do to a joint to flex/extend?
|
A muscle must span the joint anteriorly to flex and posteriorly to extend
|
|
|
|
What is the fundamental position?
|
it's the same as the anatomical position except that the palms face the sides of the body.
|
often used when discussing rotation of the upper extremity
|
|
|
Medial
|
refers to location or position toward the midline
|
i.e. the ulna is on the medial side of the forearm
|
|
|
Lateral
|
refers to location or position farther from the midline
|
i.e. the radius is lateral to the ulna
|
|
|
Caudal
|
(word root for 'tail') refers to the position or structure closer to the feet.
|
|
|
|
linear motion a.k.a. translatory motion
|
occurs more or less in a straight line from one location to another.
|
all parts of the object move the same distance, in the same direction, and at the same time,
|
|
|
rectilinear motion
|
if movement occurs in a straight line.
i.e. motion of a child sledding down a hill. |
|
|
|
curvilinear motion
|
movement occurs not in a straight line but in a curved path
|
i.e. the path a diver takes after leaving the diving board
|
|
|
angular motion a.k.a. rotatory motion
|
movement of an object about a fixed point
|
|
|
|
a wheelchair moving across the room is which type of motion?
|
linear motion
|
|
|
|
Generally speaking, most movement within the body is what?
|
angular
|
|
|
|
Movement outside the body tends to be be what?
|
linear
|
|
|
|
Movement occurs...
|
around joint axes and through joint planes.
|
|
|
|
synovial joints
|
are freely movable joints where most joint motion occurs.
|
this type of joint movement is also called osteokinematics.
|
|
|
Osteokinematics
|
the relationship of the movement of bones around a joint axes
|
i.e. humerus moving on scapula
|
|
|
arthrokinematics
|
the relationship of joint surface movement
|
i.e. humeral head's movement /c in glenoid fossa of scapula.
|
|
|
flexion begins at what degree?
|
180 (full extension)
|
|
|
|
the anatomical position is conersidered what degree?
|
zero
|
|
|
|
hyper extension
|
is the continuation of extension beyond the anatomical position
|
|
|
|
Flexion at the wrists maybe called?
|
palmar flexion
|
|
|
|
Extension at both wrists and ankles maybe be called?
|
dorsiflexion
|
|
|
|
What is the reference point for the fingers?
|
the middle finger
|
movement away from the middle finger is ABDUCTION
|
|
|
What is the point of reference for the toes?
|
the second toe
|
|
