||||
| List four actions of the sartorius muscle. | abduction, lateral rotation, and flexion of femur; flexion of knee; medial rotation of tibia (when knee is flexed and foot unweighted)
🗑
|
||||
| Action of the gracilis across the hip joint. | adduction of femur
🗑
|
||||
| action of fibularis longus | eversion of foot, plantarflexion of ankle
🗑

||||
| Action of peroneus (fibularis) tertius. | eversion of foot, dorsiflexion of ankle
🗑
|
||||

🗑
|
||||
| Action of the rectus femoris. | Flexion of Hip, Extention of knee
🗑
|
||||
| List individual names and actions of the muscles collectively known as the triceps surae. | Gastrocnemius: plantarflexion of ankle, flexion of knee; Soleus: plantarflexion of ankle
🗑
|
||||
| Action of the Plantaris. | Knee flexion, plantarflexion of ankle
🗑
|
||||
| Function of popliteus muscle. | Lateral rotation of femur to Unlock the knee, assists in medial rotation of tibia when knee is flexed
🗑
|
||||
| Action of soleus. | plantarflexion of ankle
🗑
|
||||
| Action of gastrocnemius. | plantarflexion of ankle, flexion of knee
🗑
|
||||
| function of the popliteus muscle | unlock the knee
🗑
|
||||
| Discuss what functional reversal of origin and insertion means. | Origin becomes moveable, the insertion is stabilized
🗑
|
||||
| Define the perimysium. | Connective Tissue which surrounds and holds groups (usually twelve) of endomysium wrapped muscle cells (a.k.a. fasicles, 1st thing visible to naked eye [muscle cell or fiber, endomysium, perimysium, epimysium, intermuscular septa, deep fascia] )
🗑
|
||||
| besides being external to the epimysium and sometimes fused to it, give two other characteristics of the deep fascia | divides the muscles into functional compartments via the intramuscular septa, surrounds individual muscles and allows them to freely move against each other
🗑
|
||||
| Considering that muscle volume remains constant, what can one say when comparing the range of strength of contraction of an unattached muscle. | RANGE depends on fasicle LENGTH; STRENGTH depends on fasicle CROSS SECTIONAL AREA
🗑
|
||||

🗑
|
||||
| Name the ligaments that run from the tibia to the lateral malleolus. | Anterior Tibiofibular Ligament, Posterior Tibiofibular Ligament
🗑
|
||||

🗑
|
||||
| Be able to identify from netter diagrams... | Oblique Popliteal Ligament, Ischiofemoral Ligament and suprapatellar bursa
🗑
|
||||
| a patient is flat-footed due to flattening of the medial longitudinal arch. This would indicate what specific ligamentous damage | plantar calcaneonavicular ligament
🗑
|
||||

🗑
|
||||
| considering that muscle volume remains constant. What can one say when comparing the range and strength of contraction of an unattached muscle | they are inversely related
🗑
|
||||
| Component of deep fascia which arranges muscle into functional compartments. | Intermuscular Septa
🗑
|
||||
| Smallest fiber-like unit of a muscle visible to the naked eye. (do not say fiber as your answer) | Fasicle
🗑
|
||||
| Name given to the connective tissue covering the smallest unit of muscle visible to the naked eye(don’t say fiber). | Perimysium
🗑
