3.Soleus

4.Popliteus

5.Flexor hallucis longus

6.Tibialis posterior

7.Flexor digitorum longus

8.Fibularis muscles in lateral leg

posterior leg: generel

In general:

Flex knee, (plantar)flex ankle

Tibial n. (S1-2)

Posterior tibial a.

post leg: superficial

*calcaneal tendon → calcaneous

post leg: 2nd layer

*Plantaris: → calc tendon; small assist KF and AF

*Soleus can PF in ANY POSITION; bipennate

post leg: deep layer

tendons at medial malleolus

*Popliteus: KF and KR (start KF from extension)

*FDL: medial, cross med → lat

*TP: middle

*FPL: lateral, cross lat → med

tendons at medial malleolus

nerovascular posterior leg

anterior leg: generel

Extend / dorsiflex ankle and toes

Invert ankle

Deep fibular n. (L4-5)

Anterior tibial a.

*tib ant: cross lat → med, insert med cuneiform

*not everyone has FT

lateral leg

•Evert foot

•(Weak plantarflexion of ankle)

•Superficial fibular n.

•Fibular a.

Neurovascular relationships in anterior and lateral leg + where is the fibular artery?

-fibular artery is in the post leg deep layer

ankle

-what bones compose the ankle joint

-type of joint

-Distal tibia, Distal fibula, Talus

-hinge

muscle table DF + PF

intertarsal joints

•There are several, and most have limited range of motion, or some gliding

•Two of these joints produce inversion and eversion of the foot:

1.Talocalcaneal

2.Talonavicular

muscle table inversion + eversion

MTP

-components

-type of joint

-proximal phalanges and metatarsals 1-5

-condyloid

MTP flexion muscle table

MTP extension muscle table

MTP abduction and adduction muscle table

Interphalangeal joints

-components

-type of joint

-proximal and distal phalanges of digit 1; middle and distal phalanges of digits 2-5

-hinge
