| Question | Answer |
|---|---|
| what is the purpose of miniscus | buffer between the femur and the fib/tib |
| what kind of joint is the talocrural | hinge |
| what are the differences in the different retinaculums? | wrist holds extensors/flexors; ankle has 5 ret.'s ...10 broad crossing front ankle, 2) Y-shaped distal to lateral malleolus on calcaneus spanning the ankle then branching to attach at medial malleolus and the other to the navicular, etc.... |
| location of head of fibula in relation to tibial tuberosity | lateral |
| plantar apponeurosis -where and what is it? | thick superficial band of fascia on the bottom of the foot from calcaneus to each metatarsal head |
| how many tarsal bones are there | 7 |
| how many carpal bones are there | 8 |
| O/I/A popliteus | O: lateral epicondyle of femur I: proximal posterior tibia A: flex knee & medially rotate flexed knee |
| what muscles are in the anterior compartment of lower leg | extensors: tibialis anterior, extensor digitorum longus, ext. hallicus longus |
| what muscles are in the lateral compartment of lower leg | peroneus longus and brevis |
| what muscles are in the posterior compartment of lower leg | flexors: tibialis posterior, flexor digitotrum longus, flexor hallicus longus |
| what muscle extends the big toe | extensor hallicus longus |
| what muscle will dorsiflex the foot | tibialis anterior, extensor digitorum longus, extensor hallicus longus |
| origin tibialis anterior | interosseus membrane and proximal anterior fibula |
| origin peroneus longus & brevis | distal 2/3 of lateral fibula |
| insertion of soleus | calcaneus via calcaneal tendon |
| origin gastrocnemius | posterior tibia and proximal fibula |
| what 3 muscles lead into calcaneal tendon | gastroc, soleus, plantaris |
| what is the relation of plantaris muscle in relation to gastroc and popliteous muscles | superficial |
| what action do the muscles in the lateral compartment do? | evert the foot & assist to plantar flex the ankle |
| what are intrinsic muscles of the foot | small muscles in the foot |
| what muscle originates @ ischial tuberosity | gemellus inferior |
| what 3 muscles insert @ pes anserine | sartorius, gracilis, semitendonosis |
| what makes the IT Band | superficial sheet of fascia |
| action of sartorius | flex & laterally rotate hip, adduct hip & flex knee |
| origin of biceps femoris | linea aspera (short head) and ischial tuberosity (long head) |
| origin of hamstrings | ischial tuberosity |
| where does semitendonosus lie in relation to biceps femoris | medial |
| the shortest of the adductor muscles | adductor brevis |
| what adductor inserts @ adductor tubercle | adductor magnus |
| what adductor crosses the knee joint | gracilis |
| what does the distal end of the femur articulate with | talus (?) |
| what are the boundaries of the femoral triangle | inguinal ligament, sartorius, adductor longus |
| put the adductor muscles in order from proximal to distal | pectineus, adductor brevis, adductor longus, gracilis, adductor magnus |
| what are the structures in the appendicular skeleton | arms and legs and the pectoral girdle (scapula and clavicle) and the pelvic girdle (hips) |
| what are the structures in the axial skeleton | skeleton's center cranium, vertebral column, ribs, sternum and hyoid bone |
| the combination of flexion and extention & abduction and adduction only takes place where (circumduction) | hip and shoulder |
| what is the relation of the big toe to the little toe | medial |
| what plane of motion does hip abduction occur | frontal |
| what plane divides the body into left and right | saggital |
