thigh Flashcards
3 parts of hip bone
ilium
pubis
ischium
which of the 3 parts of the hip is the widest and largert
iliium
located superiorly and has inner and external surfaces
which part of hip bone is the most anterior
pubis
consists of body, superior ramus and inferior ramus
what forms posterioinfreior part of hip bone
ischium
what does femoral head articulate with
acetabulum of hip
what is great saphenous vein formed by
dorsal venoush arch of foot and dorsal vein of great toe
where does great saphenous vein drain
femoral vein at medial aspect of thigh, immediately inferior to inguinal ligament
what lesser saphenous vein formed by
dorsal venous arch of foot and dorsal vein of little toe
where does lesser saphenous vein drain
popliteal vein in popliteal fossa
what veins drain gluteal region
inferior and superior gluteal veins, these empty into internal iliac vein
lymphatics of lower limb drain into which 3 groups of nodes
superficial inguinal
deep inguinal
poplitela
what type of joint is hip joint
ball and socket synovial joint
strong and multiaxial joint, designed for stability and weight-bearing rather than large ROM
what is the acetabulum
cup-like depression located on the inferolateral aspect of pelvis
what is the acetabular labrum
fibrocartilaginous collar that deepens the acetabular cavity
incresease in depth provides larger articularing surface, further improving joint stability
which ligaments prevent hyperextension of the hip joint
iliofemoral ligament
ischeiofemoral ligament
which ligament prevents hyper-abduction of the hip joint
pubofemoral ligament
arterial supply to hip joint
medial and lateral circumflex femoral arteries (branches of profunda femoris)
they anastomose at base of femoral neck to form a ring
damage to what artery may result in avascular necrosis of the femorla head
medial circuflex femoral artery
what nerves innervate the hip joint
sciatic, femoral + obturator nerves
what muscles cause hip flexion
iliopsoas
rectus femoris
sartorius
pectineus
what muscles cause hip extension
gluteus maximus
posterior part adductor magnus
biceps femoris (hamstrings)
what muscles cause hip adduction
adductor longus adductor brevis adductor magnus pectineus gracilis obturator externus
what muscles cause hip abduction
gluteus medius
gluteus minius
tensor fascia latae
what muscles cause hip lateral rotation
piriformis obturator internus obturator externus superior + inferior gamelli quadratus femoris
