Anatomy: Hip Joint and Posterior Thigh Flashcards
what are the muscles in the posterior compartmnet of the thigh supplied by
tibial part of sciatic nerve
except short head of biceps femoris which is supplied by common fibular part
where is the sciatic nerve derived from
lumbosacral plexus
L4-S3
how does the sciatic nerve enter the gluteal region
greater sciatic foramen
what muscle does the sciatic nerve emerge ifneriorly to in the gluteal region
piriformis
where does the sciatic nerve most commonly split into tibial and common fibular
most commonly inf 1/3 of thigh
where do the semimembranous, semitendinous and long head of biceps femoris attach proximally
ischial tuberosity
what is the most medial muscle of the hamstrings
semimembranous
what is the function of the hamstring muscles
extend and flex hip and knee joints respectively
where does teh short head of the biceps femoris attach
linea aspera of the femur
does the short head of the biceps femoris contribute to the movement of the hip
no as it doesnt cross the hip
what is the nerve supply of the short head of the biceps femoris
common fibular branch of sciatic, rather than tibial
what is the acetabulum labrum and what does it do
a fibrocartilaginous collar that deepens the acetabulum
what does ligament of head of femur attach and what happens to it in dislocation
femur to depth of acetabulum
ruptured during dislocation
what runs in the ligament of head of femur
artery to head of femur - minimal arterial supply to juvenile femur and is then obliterated in adult
