Week 2 - Motion of joints Flashcards
define flexion
bending movement that decreases angle of body parts
define extension
opposite of flexion; a straightening movement
true or false:
flexion of shoulder or hip is a backwards (dorsal) movement
false; flexion of shoulders or hips is a forward movement
true or false:
the meaning of the terms flexion and extension of the wrist are universally agreed upon
false; the usual convention is to call it palmar flexion (move anteriorly) or dorsiflexion (move posteriorly)
true or false:
the meaning of the terms flexion and extension at the ankle is not universally agreed upon
true:; the usual convention is to call it dorsiflexion (movement of foot upward at ankle) and plantar flexion (movement of foot downward at ankle)
define abduction
movement of body part away from sagittal plane
define adduction
movement of body part towards sagittal plane
how would abduction and adduction look for fingers and toes ?
fingers moving away and towards axial line of hand or foot
true or false:
flexion and extension of the thumb is moving along the sagittal plane
false; flexion and extension of the thumb is moving along the coronal plane
internal rotation is the same as
medial rotation
external rotation is the same as
lateral rotation
define opposition
motion in which parts of body are brought together - primarily used to describe hand movements in which the thumb is brought into contact with other fingers
which bones demonstrate protraction and retraction
movements of scapula on thorax, and movement of mandibles
define protraction
anterior glide - movement of scapula or mandible forward (anteriorly)
define retraction
posterior glide - movement of scapula or mandible backwards (posteriorly)
