29. Action of Superficial Muscles 1- All produce plantar flexion of foot at ankle during walking, running and ballet dancing. 2- Gastrocnemius and plantaris help flexion of knee. 3- Soleus acts as muscle pump that helps venous return.
30. Nerve Supply - All are supplied by Tibial nerve in the popliteal fossa (medial popliteal). - Soleus is supplied also by posterior tibial nerve in the back of the leg.
31. Deep Muscles (Page 150) Muscle acting on knee J.: - Popliteus. Muscles acting on ankle J.: - Tibialis posterior. - Flexor hallucis longus. - Flexor digitorum longus.

39. Action of Popliteus 1- Medial rotation of tibia. 2- Lateral rotation of femur. So, it unlocks the locked knee at the beginning of flexion. 3- Pull the lateral meniscus backwards protecting it against crushing.
40. Nerve Supply -Popliteus is supplied by medial popliteal nerve that curves around the lower border and enters the deep surface of the muscle.

123. Clinical points: 1- Fracture of neck of femur: common in old age specially in females. Types: 1- Subcapital & cervical lead to avascular necrosis to head so, synthetic prosthesis is needed. 2- Basal & inter-trochanteric fractures lead to saving the head because capsular vessels are preserved. 2- Dislocation: congenital or accidental. 3- Referred pain: from hip to knee. Dr. Sherif Fahmy
126. Abnormalities of Neck-Shaft Angle: Coxa Valga: ➢Increased angle, may be associated with congenital dislocation of hip joint. ➢Adduction is limited. Coxa Vara: ➢Decreased angle, may be associated with fracture neck of femur. ➢Abduction is limited.
