Tibialis Anterior - of the anterior lower leg

Tibialis Anterior is one of the well known lower leg muscles, maybe because it's
pretty obvious on most people :)

Tibialis: referring to the lower leg bone that the muscle runs along.
Anterior: lives on the front (aka "anterior") of the lower leg.

me activating Tibialis Anterior - it's muscle belly is right
under my finger see?

Tibialis Anterior Muscle Attachment Points

Origin:  lateral tibial condyle & the proximal 2/3 of the tibia* AND the proximal 2/3 of the interosseus membrane (see pic below) 

*the outside edge of the tibia (knee end aka proximal) right next to the fibula)

Insertion:  1st cuneiform & the first metatarsal

((aka just under the right side of your knee, travels down the tibia bone crossing at the front of the ankle, with its tendon inserting on the inside arch of your foot))

Tibialis Anterior Muscle Actions

a) dorsiflexion of the foot at the ankle joint
aka toes pointing up to the sky (& heel down towards ground)
do this 25x and feel your Tibialis Anterior BURN ;)

b) inversion of the foot at the @ the sub-talar joint:

'turning your ankle inwards'

Maintaining ankle range of motion, strength and balance between the muscles all around is so so important  - so important that I made a video about it enjoy ! :
