Hip joint Flashcards
What are the muscles involved in hip flexion?(4)
iliopsoas
rectus femoris
tensor fascia latae
sartorius
What are the muscles involved in hip extension? (4)
gluteus maximus
semimembranosus
semitendonosus
biceps femoris
What are the muscles involved in hip ABduction?(3)
Gluteus medius
gluteus minimus
tensor fascia latae
What are the muscles involved in hip ADduction? (5)
Adductor longus, brevis, magnus
gracilis
pectineus
What are the muscles involved in hip medial rotation? (7)
tensor fascia latae
gluteus minimus and medius
pectineus
adductor longus, brevis, magnus
What are the muscles involved in hip lateral rotation? (7)
obturator internus and externus piriformis gemelli quadratus femoris sartorius gluteus maximus
What are the articulating parts of the hip joint?
acetabulum and head of femu
What are the two components of the acetabulum?
articulating surface acetabular fossa (fatty tissue)
What area does the joint capsule enclose?
area from bony rim of acetabulum to neck of femur
What does the synovial membrane cover in the joint capsule?
intracapsular neck of femur
labrum
ligament of head of femur
fat pad
What are the internal ligaments of the hip?
transverse acetabular
ligament of head of femur
What are the external ligaments of the hip?
iliofemoral ligament
ischiofemoral ligament
pubofemoral ligament
What is the significance of the iliofemoral ligament?
most important, strongest in body, prevents hip hyperextension
Which ligament prevents over abduction?
pubofemoral
What supplies blood to the hip joint?
medial and lateral femoral circumflex a. (form anastomoses)
What other joint movement decreases hip flexion and why
knee extension, lengthens hamstrings to max
