| Question | Answer |
|---|---|
| gastrocnemius (24) | calf muscle - point toes |
| soleus (27) | UNDER gastrocnemius - deep muscle - plantar flexes foot |
| fibularis longus (22 or 23) | Superficial muscle - eversion of foot- lateral side [lar think lateral] |
| fibularis brevis (22 or 23) | Below fibularis longus - also eversion of foot on the lateral side [lar think lateral] |
| tibialis anterior (20) | dorsiflexion and inverts foot |
| tibialis posterior(31) | most central muscle in lower lege (take off 2 layers - deep inside lower leg)-plantar flexes and inverts foot |
| hamstrings (3) | biceps femoris; the semitendinosus and the semimembranosis |
| hamstrings: biceps femoris (18) | lateral side (back) |
| hamstrings: semitendinosus (16) | semitendinosus (medial side superficial) back |
| Hamstrings: semimembranosus (17) | deep on medial side - smaller, more inside - |
| gracilis - 13 | inside of thigh - adduction -medial straight |
| quadriceps femoris: four - rectus femoris; vastus lateralis; vastus medialis; vastus intermedius | the quadraceps femoris is actually four muscles- these muscles extend the knee |
| rectus femorus 12 | STRAIGHT across the femor - attaches to knee-extends knee |
| vastus lateralis - 11 | outside lateral of 12 |
| vastus medialis - 10 | inside - medial of 12 |
| vastus intermedius 12a | deep to rectus femoris (can't see unless you take off) |
| adductor longus 14 | putting legs together - ADDUCTOR - feel when you put legs together |
| adductor magnus 15? | putting legs together - INSIDE - straight, under, can only see top |
| gluteus maximus 1 | abduction - butt |
| gluteus medius 1a | underneath - butt |
| tensor fascia latae - 7 | stabilizer of connective tissue - lateral top |
| sartorius - 8 | Tailor's muscle - used to cross legs - crosses from anterior superior iliac spine to medial side of tibial tuberosity |
| iliopsoas | an |

| iliopsoas | flexes hip |
| extensor digitorum longus 21 | follow tendons end up at digits 2-5 [longus think lateral] |
| flexor digitorum longus 29 | flex toes - medial side |
