b) Sagittale as
c) Transversale as
1.1 VLAKKEN
Frontaal vlak Sagittaal vlak Transversaal vlak
Longitudinale en transversale as Longitudinale as en sagittale as Sagittale as en transversale as
Voorste- achterste deel Rechter- en linkerhelft Boven- en onderzijde
Mediaanvlak of midsagittale vlak
Evenwijdig met voorhoofd Evenwijdig met vloeroppervlak
(= vlak precies in middenlijn)
Dwarsdoorsnede van het lichaam
Loodrecht op mediaanvlak Loodrecht op frontale vlak

Analyse van de beweging 1
, 2. BEWEGINGSRICHTINGEN
Terminologie
Flexie, flexio Buiging
Extensie, extensio Strekking
Weg van het lichaam, naar
Abductie, deviatie, abductio
buiten trekken
Adductie, adductio Naar het lichaam toe, aantrekken
Rotatie, rotatio Draaiing, beweging rond een as
Anteflexie (naar voor) en retroflexie (naar achter) van
het been (heup) en de arm (schouder) = flexie en
extensie
Flexie bovenarm/dij = anteflexie
Extensie bovenarm/dij = retroflexie
Elevatie = opheffen van arm of dij boven de
horizontale lijn
Hyperextensie = Beweging verder dan normale bewegingsomvang
Anteversie van het bekken = naar voor kantelen
Retroversie van het bekken = naar achter kantelen
Lateroflexie = laterale flexie (kromming WK)
Flexie hand vanuit pols
· Palmaire flexie (handpalm)
· Dorsiflexie, dorsaalflexie (handrug)
