FLEXIONknee flexors are a
group of muscles
which cross the
posterior of
the knee joint
whose
contraction
induces flexion o
f the joint.

EXTENSION
Extension is a movement of a joint that results in increased angle between two bones or body surfaces at a joint.

INWARD ROTATION
Internal rotation
(also known as medial rotation) is rotation towards the center of the body.

OUTWARD ROTATION
External rotation (or
lateral rotation) is rotation away
from the center of the body.

DORSI FLEXION
PLANTER FLEXION
INVERSION
EVERSION

DORSI FLEXION
Dorsi flexion is the movement which decreases the anglebetween the dorsum (superior surface) of the foot and the leg, so that the toes are brought closer to the shin.

PLANTER FLEXION
Plantar flexion is the
movement which
increases the
approximate 90
degree angle
between the front
part of the foot and
the shin,

INVERSION & EVERSION
• Inversion is the movement of the sole towards the median plane (as when an ankle is twisted).
• Eversion the anatomical term of motion denoting the movement of the sole of the foot away from the median plane
