Positioned above a point of reference.
Positioned below a point of reference.
Positioned nearest the center of the body, or point of reference.
Positioned farthest from the center of the body, or point of reference.
Anterior (or ventral):
On the front of the body.
Posterior (or dorsal):
On the back of the body. (Think dorsal fin).
Positioned near the middle of the body.
The terms anterior, posterior, medial & lateral, abduction & adduction apply to the body when it is in the anatomic position.
An imaginary bisector that divides the body into left and right halves.
A bending movement in which the relative angle btwn two adjacent segments decreases.
An example of adduction/abduction in the frontal plane and anterior-posterior axis would be a __________.
Side lateral raise.
A straightening movement in which the relative angle btwn two adjacent segments increases.
Extension of a joint beyond the normal limit or range of motion.
An imaginary bisector that divides the body into front and back halves.
A movement in the frontal plane away from the midline of the body. (Think: alient ABduction)
Movement in the frontal plane back toward the midline of the body.
An imaginary bisector that divides the body into top and bottom halves.
Rotation of a joint toward the middle of the body.
Rotation of a joint away from the middle of the body.
Movement of the arm or thigh in the transverse plane from an anterior position to a lateral position.
Movement of the arm or thigh in the transverse plane from a lateral position to an anterior position.
ADduction of scapula; shoulder blades move toward the midline.
ABduction of scapula; shoulder blades move away from the midline.
Downward (inferior) motion of the scapula.
Upward (superior) motion of the scapula.
**Eccentric Muscle Action:
A muscle develops tension while lengthening.
Decelerates or reduces force.
**Concentric Muscle Action:
Moving in opposite direction of force. Accelerates or produces force. Muscle shortens.
**Isometric Muscle Action:
Muscular force equal to resistive force. No visible change in the muscle length. Stabilizes force.
An influence applied by one object to another, which results in an acceleration of the second object.
The resting length of a muscle and the tension the muscle can produce at this resting time.
**What is an example of muscle being out of alignment and not generating enough force?
Muscle groups moving together to produce movement around a joint.
A force that produces rotation. Common unit of torque is the newton-meter or Nm.
The process whereby sensory info is used by the body to reactively monitor movement and the environment.
**What muscle concentrically accelerates or does hip extension?
