Inferior LImb
| Inferior Limb | Infomation |
|---|---|
| Obturator Internus (Deep hip rotator) | Origin: obturator foreman Insertion: greater trochanter of femur Function: lateral rotation |
| Superior gemellus (deep hip rotator) | Origin: spine of ischium Insertion: greater trochanter of femur Function: lateral rotation |
| inferior gemellus (deep hip rotator) | Origin: ischium Insertion: greater trochanter of femur Function: lateral rotation |
| Quadratus femoris (deep hip rotator) | origin: ischial tuberosity insertion: greater trochanter of femur function: lateral rotation of hip |
| piriformis (deep hip rotator) | origin: anterior sacrum insertion: greater trochanter of femur function: lateral rotation (sciatic nerve- largest nerve cord in body passes through the sciatic notch of oscoxa then piriformis. sciatic nerve enervates posterior thigh and lower leg.) |
| Obturator externus (deep hip rotator) | origin: obturator foramen insertion: greater trochanter of femus function: lateral rotation of hip joint |
| gluteus minimis (gluteal muscles) | origin: posterior ilium b/w anterior and inferior gluteal lines insertion: greater trochanter of femur function: abductor of hip joint, medial rotation of femur at hip |
| gluteus medius (gluteal muscles) | origin: iliac crest b/w anterior and posterior gluteal lines insertion: greater trochanter of femur function: abduction of hip joint, medial rotation of femur at hip |
| gluteus maximus (gluteal mucles) | origin: posterior sacrum, posterior iliac crest insertion: gluteal tuberosity of femur and iliotibial tract function: extension of femur at hip, lateral rotation of extended hip, assist with abduction of hip joint |
| tensor fascia latae (gluteal muscles) | origin: anterior iliac crest, ASIS insertion: iliotibal tract function: assist with abduction, medial rotation, flexion of femur at hip, extension of knee |
| psoas major (hip flexor) | origin: t12-L5 insertion: lesser trochanter of femur function: flexion and weak lateral rotation |
| iliacus (hip flexor) | origin: inner surface of ilium insertion: lesser trochanter of femur function: flexion and weak lateral rotation |
| pectimeus (medial thigh compartment) | origin: pectineal line of pubis insertion: linea aspera function: adduction and flexion of hip joint |
| adductor brevis (medial thigh compartment) | origin: external surface of pubic body and inferior ramus insertion: linea aspera function: adduction of hip joint, lateral rotation when off ground... medial with on ground |
| adductor longus (medial thigh compartment) | origin: anterior surface of pubis insertion: linea aspera function: adduction and flexion of hip |
| adductor minimis (medial thigh compartment) | origin: inferior pubic ramus insertion: gluteal tuberosity function: adduction of hip |
| adductor magnus (medial thigh compartment) | origin: ischial ramus and ischial tuberosity insertion: linea aspera and medial supracondylar line function: adduction and extension of hip |
| gracilis (medial thigh compartment) | origin: inferior ramus of pubis insertion: anteromedial surface of proximal tibia function: flexion of knee, medial rotation of knee, assist with adduction of hip |
| Vastus intermedius (anterior thigh compartment) | origin: anterior and lateral femoral shaft insertion: tibial tuberosity function: extension of knee (quadricep) |
| vastus lateralis (anterior thigh compartment) | origin: greater trochanter insertion: tibial tuberosity function: extension of knee (quadricep) |
| vastus medialis (anterior thigh compartment) | origin: linea aspera insertion: tibial tuberosity function: extension of knee (quadricep) |
| rectus femoris (anterior thigh compartment) | origin: spine of ilium insertion: tibial tuberosity function: flexion of hip, extension of knee (quadricep) |
| sartorius (anterior thigh compartment) | origin: ASIS insertion: tibia surface function: flexion and lateral rotation of hip, flexion of knee |
| biceps femoris (posterior thigh compartment) | origin: ischial tuberosity, linea aspera function: head of fibula function: extension of hip, flexion of knee |
| semimembranosus (posterior thigh compartment) | origin: ischial tuberosity insertion: medial condyle of tibia function: extension of hip, flexion of knee |
| semitendinosus (posterior thigh compartment) | origin: ischial tuberosity insertion: medial shaft of tibia function: extension of hip, flexion of knee |
| popliteus (posterior crural compartment) | origin: lateral condyle of femur insertion: posterior proximal tibial shaft function: unlocks knee |
| soleus (posterior crural compartment) | origin: soleal line of tibia insertion: calcaneus function: planter flexion |
| gastrocnemius (posterior crural compartment) | origin: medial and lateral epicondyle of femur insertion: calcaneus function: planter flexion of ankle, assist with flexion of knee |
| plantaris (posterior crural compartment) | origin: lateral condyle of femur insertion: calcaneus function: planter flexion of ankle, assist with flexion of knee |
| ischial spine | seperates greater and lesser sciatic nerves |
| splenius cervicus | deep to rhomboid minor |
