Movement & muscle knee & Ankle Joint
Movement on Knee Joint
FLEXION
EXTENSION
INWARD ROTATION
OUTWARD ROTATION
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.
KNEE JOINT-MUSCLES INVOLVED• FLEXION:- SEMITENDI-
NOSUS, SEMIMEMBRA-NOSUS OR BICEPS FEMORIS
• EXTENSION:- RECTUS FEMORIS OR VASTUS GROUP
• INWARD ROTATION:-SEMITENDI-NOSUS, SEMIMEMBRA-NOSUS
• OUTWARD ROTATION:-BICEPS FEMORIS
Rectus Femaris & Vastus Group
MOVEMENT OF ANKLE & FOOT JOINT
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
ANKLE & FOOT JOINT- MUSCLES INVOLVED
• Dorsi flexion :- Tibialis
, Extensor Digitorum
longus.
• Planter Flexion:-
Gastrocnemius or
soleus.
• Inversion:- Tibialis
Anterior.
• Eversion:- extensor
Digitorum
