Vert Bio- Exam 2 Flashcards
Levator
elevate; moves body to superior position
Depressor

Extension
To open, or unfold. increase angle of a joint
Hyperextension
Increase angle of joint beyond normal
Flexion
Fold or decrease angle between bones/body regions
Lateral Flexion
Trunk/neck: movement in frontal plane away from median. Side bending.
Adduction
Pull toward midline
Abduction
Pull away from midline
Lateral Rotation
Movement in transverse plane that takes part of body outward
Medial Rotation
Movement in transverse plane. Takes part of body inward
