Question 1

What is the femoral triangle

Answer 1

-Anatmical region of upper thrird of thigh , med aspect
-subfascial space with triangular depression below inguinal lig
-region of passage of main blood vessels b/w pelvis & lower limb and larges nerve supplying thigh

Question 2

borders of femoral triangle

Answer 2

lat-sartoris
med-adductor longus
sup-inguinal lig.

Question 3

floor
roof

Answer 3

floor:
4 muscles-
1.adductor longus
2.pectineus
3.psoas major
4.iliacus

roof: 1.fascia latae
2.superficial fascia
3.skin

Question 4

contents of f.t (lat-med)

Answer 4

1. Femoral nerve: has ant & post branches that Innervates the anterior compartment muscles of the thigh and provides sensory branches
2. Femoral artery: continuation of external iliac artery ( branches: Superficial Epigastric ,Superficial Circumflex Iliac ,Superficial External Pudendal ,Deep External Pudendal ,
   Profunda Femoris ,Medial & Lateral Circumflex Femoral , Descending Genicular) continue as is until knee where it become popliteal a
   3.Femoral vein: from great saphenous veins and drain external iliac vein in plevis
   4.Empty space of femoral canal
   5.Lymphatics

All contents excepts femoral n are enclosed by femoral sheath, its continuous sup. with transversalis fascia & iliac fascia in abdomen. Each structures is enclosed alone. Femoral canal has a proximal ring - femoral ring bounded by ant-inguinal lig, post-lacuna lig, med-lacunar lig and lat-femoral vein

Question 6

ADDUCTOR CANAL

Answer 6

The adductor canal, also known as Hunter’s canal or the subsartorial canal, conduit from femoral trinagle to popliteal fossa

Location
Proximal End: Begins at the apex of the femoral triangle.
Distal End: Ends at the adductor hiatus (an opening in the adductor magnus muscle), where the femoral vessels pass into the popliteal fossa.

Boundaries
Anterior and Lateral: Vastus medialis muscle.
Posterior: Adductor longus and adductor magnus muscles.
Medial (Roof): Sartorius muscle and the subsartorial fascia.

Contents:
-Femoral artery: becomes popliteal a when exits adductor hiatus
-Femoral vein
-Saphenous n:branch of the femoral nerve that provides sensory innervation to the skin of the medial leg and foot.
-descending genicular a: supplies structure of knee, branch of femoral a

Question 7

popliteal fossa

Answer 7

a diamond-shaped anatomical region located at the back of the knee.

Boundaries of the Popliteal Fossa
Superolateral: Biceps femoris muscle
Superomedial: Semimembranosus and semitendinosus muscles
Inferolateral: Lateral head of the gastrocnemius muscle and plantaris muscle
Inferomedial: Medial head of the gastrocnemius muscle
Roof: Popliteal fascia and skin
Floor: Popliteal surface of the femur, the posterior aspect of the knee joint capsule, and the popliteus muscle

contents:
-popliteal a : lies deep to vein, supplies knee joint & muscles of lower leg
-popliteal v: union of ant. & post. tibial veins
-tibial nerve : large terminal branch of sciatic nerve/ posterior compartment muscles of the leg and provides sensory innervation to the skin of the sole of the foot.
-common fibular nerve : Smaller terminal branch of the sciatic nerve/muscles of the anterior and lateral compartments of the leg
