what structure passes thru the saphenous hiatus (saphenous opening, or fossa ovalis)?

long saphenous vein
abdominal aorta branches off into the:

R and L common iliac arteries
the EXTERNAL iliac artery passes under the inguinal ligament and emerges as the:

femoral artery
femoral artery gives off the:

deep femoral artery
what is the main artery that supplies the thigh?

deep femoral artery
the deep femoral artery gives off 2 branches:
- medial circumflex artery
- lateral circumflex artery
medial and lateral circumflex arteries give off muscular branches that supply:

posterior thigh muscles
the superior and inferior gluteal artery arise from the:

INTERNAL iliac artery
superior & inferior gluteal arteries pass one above and below what muscle:

piriformis
what structure does the sup and inf gluteal arteries pass thru?

greater sciatic foramen
anterior rami is numbered by the segmen of the spinal column which lies:

above it
meniscus is made of:

flexible fibrocartilage
2 ends of the meniscus are attached to the:

intra-articular area
there is a medial and a lateral part of the meniscus. which is further apart and which is close together?
- further apart: medial
- close: lateral
which (lateral or medial) is more MOBILE? why?

lateral is more mobile. its 2 medial attachments are close together & the mobility of the joint capsule around the edge
what knee ligament DOES NOT blend with the joint capsule and is NOT attached to the lateral meniscus?

Fibular collateral ligament
what knee ligament IS attached in the joint capsule in front and behind is firmly attached to the medial meniscus?

tibial collateral ligament
when the knee joint is extended, both collateral ligaments are:

TIGHT

they are less tight in flexion
what is the function of the knee collateral ligaments?

to keep the medial & lateral condyles together & prevent the knee joint from bending from side to side
deepest head of the quadriceps?

vastus intermedius
when workings as an anti-gravity muscle, the quads:
- lift body upward when climbing hills
- propels us forward when pushing a heavy load
the adductor canal lies btwn:

vastus medialis and adductor longus
what structures run thru the adductor canal?
- femoral vein and artery
- saphenous nerve
what are the borders of the adductor canal:
anteriorly?
postmed?
laterally?
- ant: sartorius
- postermedially:adductor longus & adductor magnus
- lat: vastus medialis
attachments for the semimembranosis & semitendinosis:
- ischial tuberosity
- medial side of the knee
attachments for the biceps femoris:
- ischial tuberosity
- femur
- head of fibula
when flexion of the knee is restricted by contraction of the quads, the hamstrings will produce:

extension of the hip
when extension of the hip is restricted by hip flexors, the hamstrings produce:

flexion of the knee
function of the hamstrings acting separately:

produce medial rotation & lateral rotation @ the knee joint
function of the 2 semi muscles:

produce medial rotation of the tibia
function of the bicep femoris:

produce lateral rotation
