it is a fascia thats surrondeds the femoral arteyr , vein and lymphatuc vessels in the femoral triangle for 2.5 cm below teh inguinal lgament

81

the femoral sheath is formed by

A

the downward extension of the abdomiunal fascia

82

two septa

83
Q

lateral compartment of femoral sheath

medial compartment of the femoral sheath

A

occupied by lymph vessels and also called teh femoral canal

85

contains the femoral vein

86
Q

adductor canal description

A

it is an intermuscylar cleft located in teh medial aspect of the middle third of the thigh below the sartorious muscle
it starts at the apex of the femoral triangle and ends at the adductor hiatus

87

the femoral vein
deep lymph vessels
the sapphenous nerve
the terminal part of obturator nerve
the berve to vastus medialis

88
Q

femoral arteyr description

A

it enters the thigh behind teh inguinal ligament as a continuation of the external illiac artery
it lies midway between the anterior superior illiac spine and the ysmphysis pubis ( midinguinal point)
as it continues down it lies superficial in the upper haldf in the femoral traingle and while in the lower half it becomes deep in the adductor canal

it enters teh popliteial space as the popliteal artery

91
Q

femoral artery formation

A

the abdominal arteyr divides into left and right common illiac arteries at the level of L 4 and each common artery divides into external and internal illoac arteries and evry external illiac artery becomes a femoral artery

92
Q

femoral artery journery down the leg

A

The fomral artery begins at the midiguinal point below inguinal ligament and at the opening in the adductor magnus muscle it becomes THE POPLITEAL ARTERY

The popliteal artery
Ends at the lower border of the popliteus muscle by dividing into
ANTERIOR AND POSTERIOR TIBIAL
ARTERIES

The anterior tibial artery supplies
the anterior compartment of the leg and terminates
in front of the ankle joint by becoming
THE DORSALIS PEDIS ARTERY

The posterior tibial artery supplies the posterior
and the lateral compartments of the leg
ends deep to the flexor retinaculum by dividing
Into
MEDIAL AND LATERAL PLANTER ARTERIES
