Unit 3 (Hind limb vas/nerves and head/nervous system) Flashcards
Where does the external iliac artery arise from the aorta?
Level of the 6th or 7th lumbar vertebrae.
Vascular lacuna
The point at which the external iliac crosses the abdominal wall and becomes the femoral artery (medial circumflex femoral a. also passes here)
Located in the aponeurosis of the external abdominal oblique (also called the inguinal ligament).
Caudal gluteal artery
Larger of two terminal branches of the internal iliac a. (other is internal pudendal)
Gives off cranial gluteal artery and iliolumbar artery.
Cranial gluteal artery
From the caudal gluteal artery.
Supplies the middle and deep gluteal mm.
Iliolumbar artery
From the caudal gluteal artery.
Supplies the psoas major, iliopsoas, sartorius, tensor fasciae latae, and middle gluteal mm.
Deep femoral
Only branch of the external iliac
To the pudendoepigastic trunk and the medial circumflex femoral a.
Pudendoepigastric trunk
Gives rise to the caudal epigastric artery and the the external pudendal artery.
Caudal epigastric artery
Branch of the deep femoral
Supplies the ventral surface of the abdominal wall.
Mainly rectus abdominis and oblique, transversus abdominalis.
External pudendal artery
Passes through the inguinal canal and supplies the external prepuce.
What muscles bound the femoral triangle?
Sartorius
Vastus medialis/rectus femoris
Pectineus/adductor
Medial circumflex femoral artery
Continuation of the deep femoral and leaves the abdomen in the vascular lacuna.
Deep branch
Transverse branch
Deep branch of the medial circumflex femoral a.
Smaller of the two branches.
Supplies adductor and vastus medialis mm.
Transverse branch of the medial circumflex femoral a.
Larger of the two branches.
Supplies semimembranosus m.
Femoral artery
Continuation of the external iliac a. Branches: Superficial circumflex iliac a. Lateral circumflex femoral a. Proximal caudal femoral a. Saphenous a. Descending genicular a. Middle caudal femoral a. Distal caudal femoral a. Terminates in the popliteal artery.
Superficial circumflex iliac. a.
Supplies sartorius, tensor fasciae latae, and the rectus femoris.
Lateral circumflex iliac a.
Supplies all four head of the quadriceps, tensor fasciae latae, superficial and middle gluteals, and the hip joint.
Proximal caudal femoral a.
Supplies pectineus, adductor, and gracilis.
Saphenous a.
Medial side of the leg only.
Supplies the skin on the medial side of the stifle.
Terminates in a cranial and caudal branch.
Descending genicular a.
Supplies the medial stifle
Arises at approximately the same level of the saphenous and the middle caudal femoral a.
Middle caudal femoral a.
Supplies adductor and semimembranosus mm.
Distal caudal femoral a.
Supplies biceps femoris, semimembranosus, semitendinosus, gastrocnemius, and the digital flexors.
Popliteal a.
Termination of the femoral a.
Supplies the stifle, gastrocnemius, and popliteus mm.
Terminates as the cranial and caudal tibial aa.
Lateral saphenous vein
Not paired with an artery
Used for venipuncture in the dog.
Terminates in the distal caudal femoral vein .
Cranial branch of the saphenous artery.
Supplies flexor surface of the tarsus and terminates in the dorsal common digital arteries.
