NWHSU Mash GA1Q2 Action and Definitions
Question | Answer |
---|---|
action of gluteus minimus | abduction and medial rotation of femur |
Action of the gluteus medius. | abduction and medial rotation of femur |
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 semitendinosus across the hip joint. | extension of femur |
Two primary actions of the gluteus maximus. | extension of femur, lateral rotation of extended hip |
Action of pectineus. | adduction, medial rotation, and flexion of femur |
action of semitendinosus across the knee joint | flexion and medial rotation |
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 |
a patient presents a sprained ankle caused by excessive inversion. give specific ligamentous damage. | anterior talofibular ligament |
Name the ligaments that run from the tibia to the lateral malleolus. | Anterior Tibiofibular Ligament, Posterior Tibiofibular Ligament |
A patient presents a sprained ankle caused by excessive eversion. Give specific ligamentous damage. | Deltoid ligament |
A ligament deep to the dorsal sacroiliac ligament, located in the deep groove between the sacrum and the ilium. | interosseous sacroiliac 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 |
Name 2 important ligaments with attachments to the ischium and sacrum. | sacrospinous ligament; sacrotuberous 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 |
