-
the three gluteal muscles, in order, from most superficial to most deep are:
gluteus maximus, gluteus medius and gluteus minimus
-
gluteus maximus
extends the hip joint during walking uphill (changing the level of the body) but not during walking on a flat surface
-
gluteus medius
abducts and medially rotates the femur
-
gluteus minimus
acts as a medial rotator of the thigh joint
-
sciatic nerve
major nerve that runs through the gluteal region
-
six deep lateral rotators:
1) piriformis, 2) obturator internus, 3) obturator externus, 4) quadratus femoris, 5) gemellus superior and 6) gemellus inferior
-
greater trochanter
most common insertion place of the six deep lateral rotators
-
iliotibial tract/fascia lata
deep fascial band that runs from the ilium to the tibia
-
the semimembranosus and semitendinosus
are two medial hamstrings which attach to the tibia at their lower end (ischial tuberosity pelvis to tibia)
-
biceps femoris
is the lateral hamstring muscle which attaches to the fibula at its lower end (ischial tuberosity pelvis to fibula)
-
ischial tuberosity of the pelvis
where all three hamstrings attach to at their upper end
-
the primary action of the medial thigh muscles:
is to adduct the femur
-
the four medial thigh muscles that cross only
the hip joint (one-joint muscles) are the:
pectineus, adductor brevis, adductor longus and adductor magnus
-
pubis
the feature of the pelvis that provides the upper attachment of the medial thigh muscles
-
linea aspera
the feature of the femur that provides the lower attachment of the medial thigh muscles
-
the four muscles that join in common insertion via the quadriceps tendon are the:
rectus femoris, vastus lateralis, vastus intermedius and vastus medialis
-
vasti muscles
the three quadriceps muscles that only cross the knee joint and extend the knee
-
rectus femoris
crosses both the thigh and knee joints, and both flexes the hip and extends the knee (anterior inferior iliac spine to tibia)
-
sartorius
the two-joint muscle of the anterior thigh that does not participate in the quadriceps group; also called the quadriceps tendon and patellar ligament (anterior superior iliac spine to tibia)
-
the muscles located on the anterior lower leg:
anterior tibialis, extensor digitorum longus, and extensor hallucis longus
-
"peroneal" muscles
fibularis brevis and fibularis longus; located in the lateral compartment of the lower leg
-
muscles located on the posterior lower leg:
gastrocnemius, soleus, plantaris, popliteus, flexor digitorum longus, and flexor hallucis longus
-
all the anterior leg muscles are _________ of the _______
dorsiflexors; ankle
-
all the lateral leg muscles (___________ muscles) are _________ of the _______
fibular/peroneal; everters; ankle
-
anterior tibialis
dorsiflexes the ankle and inverts the foot
-
achilles tendon
attaches the gastrocnemius, soleus and plantaris to the calcaneus
-
gastrocnemius
is a two-joint muscle; performs knee flexion and ankle plantarflexion (posterior femoral condyles to Calcaneus via Achilles tendon)
