what is the innervation of superior gemellus and obturator internus (lateral rotators)
Nerve to obturator internus
What is the innervation of inferior gemellus and quadratus femoris
Nerve to quadratus femoris
Describe piriformis syndrome, symptoms, and common activities that cause it
Label the nerve innervation and the muscle
Where should intramuscular injections be applied
What muscles are supplied by the superior gluteal artery
Glute max, med, min, and TFL
What muscles are supplied by the inferior gluteal artery
Glute max, obturator internus, gemelli, quadratus femoris, and superior portion of hamstrings
What are the 3 muscles that make up the hamstrings (posterior compartment)
What are the 4 characteristics shared among the hamstring muscles
What is the origin of the bicep femorus
Long head from ischial tuberosity and linear aspera and short head from distal femur
What is the insertion of the biceps femoris
Common tendon inserts into head of fibula and lateral condyle of tibia
What is the action of the biceps femoris
HE, KF, LR
What is the innervation of the biceps femoris
Sciatic nerve (tibial nerve to long head and fibular nerve to short head)
What is the origin of semimembranosus
Ischial tuberosity
What is the insertion of semimembranosus
Medial condyle of tibia to lateral condyle of femur
What is the action of semimembranosus
HE, KF, MR
What is the innervation of semimembranosus
Sciatic nerve (tibial branch)
What is the origin of Semitendinosus
Ischial tuberosity
What is the insertion of semitendinosus
Medial aspect of upper tibial shaft (pes anserinus)
What is the action of semitendinosus
HE, KF, MR
What is the innervation of semitendinosus
Sciatic nerve (tibial branch)
What 3 muscles insert on pes anserinus
Label the image for palpations
What are the nerves that make up the posterior compartment
Sciatic nerve that branches into:
1. Tibial nerve
2. Common fibular nerve
T or F: The sciatic nerve is so large it has its own blood supply
T, called artery to sciatic
Label the blood supply of the posterior compartment
